Health and Safety Consultants Hamilton Ontario | Guide

Hamilton, Ontario is one of Canada's most industrially significant cities — producing 60% of Canada's steel output through ArcelorMittal Dofasco and National Steel Car, housing the second largest hospital network in Ontario through Hamilton Health Sciences and St. Joseph's Healthcare, and anchoring the Golden Horseshoe's manufacturing and food processing economy alongside global brands including Maple Leaf and Bunge. With more than 70,000 Hamilton residents employed in healthcare, life sciences, and manufacturing, and a total Census Metropolitan Area employment base of approximately 425,000, health and safety compliance is both a legal imperative and a practical necessity for every Hamilton employer. Ontario's Occupational Health and Safety Act (OHSA), enforced by the Ministry of Labour, Immigration, Training and Skills Development (MLITSD), creates comprehensive obligations that were significantly strengthened by the Working for Workers Seven Act 2025. This guide covers 12 essential things businesses in Hamilton, Ontario need to know about health and safety consultants and compliance.

Why Hamilton Businesses Need Specialist Health and Safety Support

Hamilton's industrial heritage and economic diversity create a health and safety compliance environment that is among the most demanding in Ontario. Steel manufacturing, heavy industrial production, construction, healthcare, food processing, and logistics all carry distinct risk profiles and operate under sector-specific regulations that add to the foundational requirements of the OHSA.

The city's economy is overwhelmingly shaped by small enterprises — micro-sized businesses of one to four employees make up 57.3% of all Hamilton businesses, and small businesses of five to 99 employees account for a further 40.8%. These smaller employers typically lack in-house health and safety expertise and depend on external consultants to fulfil their legal obligations.

At the same time, Hamilton's major employers — ArcelorMittal Dofasco, Hamilton Health Sciences (approximately 18,000 staff), McMaster University, and the City of Hamilton (over 8,000 full-time workers) — operate in sectors where health and safety management is among the most complex and actively inspected in Ontario.

For international businesses with operations in Hamilton — whether through manufacturing partnerships, distribution facilities, healthcare research collaborations, or technology ventures linked to McMaster Innovation Park — OHSA compliance creates obligations that UK, European, and US health and safety frameworks do not automatically satisfy.

Health and Safety Consultants who understand Ontario's specific legislative framework, Hamilton's dominant sectors, and the MLITSD's enforcement priorities provide materially more effective support than generic advisers without provincial expertise.

1. The Ontario Occupational Health and Safety Act (OHSA): The Foundation of Compliance

The Occupational Health and Safety Act (OHSA) is Ontario's foundational workplace health and safety legislation. It applies to most workers, supervisors, employers, and workplaces in the province — including all of Hamilton's diverse industries.

The main purpose of the OHSA: The OHSA provides the legal framework to achieve the goal of protecting workers from health and safety hazards on the job by setting out duties for all workplace parties and rights for workers, establishing measures and procedures for dealing with workplace hazards, and providing for enforcement of the law where compliance has not been achieved voluntarily.

The Internal Responsibility System (IRS): A core principle of Ontario health and safety law is the Internal Responsibility System — the concept that every workplace party shares responsibility for health and safety. This means employers, supervisors, and workers each have distinct legal duties, not merely a general obligation to be "safe." The Ministry of Labour's goal is for all workplaces to achieve self-compliance with OHSA and regulations through a well-functioning IRS.

Employer duties under the OHSA:

Take every precaution reasonable in the circumstances for the protection of a worker
Ensure equipment, materials, and protective devices are provided and maintained
Provide information, instruction, and supervision to workers for their protection
Acquaint workers with workplace hazards
Appoint competent persons as supervisors
Where required, prepare and review a written occupational health and safety policy annually
Establish and maintain a program to implement the health and safety policy
Post the OHSA in the workplace along with explanatory material from the MLITSD

OHSA penalties: Employers who contravene the OHSA can face fines of up to $1,500,000 per charge. The maximum fine for an individual is $100,000 and/or imprisonment for up to 12 months. The Working for Workers Seven Act 2025 (which received Royal Assent on November 27, 2025) introduced a new administrative penalty scheme as of January 1, 2026 — allowing MLITSD inspectors to issue penalty notices for non-compliance without requiring prosecution.

2. The Working for Workers Seven Act 2025: What Hamilton Employers Must Know

Ontario's Working for Workers Seven Act 2025 (Bill 30) received Royal Assent on November 27, 2025 and introduced significant changes to the OHSA and related legislation that directly affect Hamilton employers.

New administrative penalty scheme (in force January 1, 2026): A new Part IX.1 introduces an administrative penalty scheme that allows inspectors to issue penalty notices for non-compliance with the OHSA or its regulations. Specific penalty amounts are determined by regulation. Crucially, if a person pays the administrative penalty, they cannot be charged with a criminal offence under the OHSA for the same contravention. The Ministry may publish the names of persons against whom administrative penalties are imposed, the nature of the contravention, and the penalty amount — creating reputational as well as financial consequences for non-compliance.

Defibrillator requirements: Construction projects expected to last three months or more and employing 20 or more workers must have automated external defibrillators (AEDs) on site. The WSIB will reimburse eligible employers for defibrillator costs (for defibrillators purchased between July 1, 2025 and June 30, 2027, up to $2,500 per defibrillator).

Equivalency of accredited safety systems: Health and safety management systems accredited by Ontario's Chief Prevention Officer must now be treated as equivalents where required under the OHSA. This encourages Hamilton employers to invest in accredited management systems — the equivalent provision strengthens the value of ISO 45001 and similar accredited standards.

Washroom cleaning documentation (in force January 1, 2026): Constructors and employers must maintain documentation of washroom cleaning activities, including the date and time of the two most recent cleanings for each washroom facility.

These amendments signal Ontario's continuing legislative trajectory: stronger enforcement tools, greater transparency about non-compliance, and higher expectations of management systems across all workplaces.

3. MLITSD Enforcement: How the Ministry Inspects Hamilton Workplaces

The Ministry of Labour, Immigration, Training and Skills Development (MLITSD) is the primary enforcement body for the OHSA in Ontario, including all Hamilton workplaces subject to provincial jurisdiction.

Ministry inspector powers: Inspectors are the enforcement arm of the Ministry. Their role includes conducting workplace inspections, issuing compliance commitments and/or orders where there is a contravention of the OHSA or its regulations, and investigating critical injuries, fatalities, work refusals, and health and safety complaints.

Inspectors can enter most Ontario workplaces without prior notice or a warrant, examine documents, speak to workers and supervisors, and issue orders requiring compliance within specified timeframes.

Types of enforcement action: - Compliance orders: Requiring specific actions to address identified contraventions within a defined period - Stop-work orders: Immediately halting dangerous activities or work processes - Administrative penalty notices (from January 2026): Financial penalties without prosecution for specified contraventions - Prosecution: For serious or repeated breaches, resulting in fines up to $1.5 million per charge

Federal jurisdiction: Hamilton workplaces that are federally regulated — including interprovincial transportation, federal Crown corporations, banks, and airlines — are subject to Part II of the Canada Labour Code rather than the OHSA. This is an important distinction for Hamilton businesses involved in rail (National Steel Car's connections to CN and CP), port operations (Hamilton Port Authority), and interprovincial logistics.

Workplace Safety and Insurance Board (WSIB): The WSIB provides Ontario's workers' compensation system. Hamilton employers are required to register with the WSIB (unless specifically exempt), pay WSIB premiums, report workplace injuries and occupational illnesses, and comply with return-to-work obligations. WSIB premium rates reflect sector risk ratings — Hamilton's manufacturing, construction, and healthcare sectors typically carry higher-than-average rates, making effective injury prevention a direct financial benefit alongside its legal and human dimensions.

4. Joint Health and Safety Committees and Health and Safety Representatives

One of the most distinctive features of Ontario's OHSA framework — and one that differs significantly from UK and European approaches — is the requirement for Joint Health and Safety Committees (JHSCs) and Health and Safety Representatives.

Health and Safety Representative (6-19 regularly employed workers): A Health and Safety Representative is required when there are six to 19 employees. They should be selected by workers not in management positions (or by the union in unionised workplaces). Representatives have a broad range of rights including the right to inspect the workplace, investigate accidents, and make recommendations to the employer.

Joint Health and Safety Committee (20 or more regularly employed workers): A JHSC is mandatory when there are 20 or more regularly employed workers. The JHSC must: - Be composed of at least two members, including at least one worker representative and one management representative - Meet at least once every three months - Conduct regular workplace inspections - Investigate workplace accidents and incidents - Make recommendations on health and safety matters - Maintain written records of meetings and recommendations

JHSC member certification: At least two JHSC members must complete mandatory certification training — Basic Certification training followed by Workplace-Specific Hazard Training. This must be done through a Ministry of Labour-approved trainer. Hamilton businesses should be aware that payment for JHSC member certification training is a required employer obligation under OHSA regulations.

For UK and international businesses establishing operations in Hamilton, the JHSC requirement represents a fundamentally different approach to worker participation from the HSE's framework. UK safety representatives have statutory rights, but the mandatory committee structure with certification requirements is more prescriptive.

Health and Safety Consultants familiar with Ontario requirements help businesses establish JHSC structures that meet legal obligations and create genuinely effective worker participation.

5. Hamilton's Steel and Heavy Manufacturing Sector: Ontario's Industrial Heart

Hamilton produces approximately 60% of Canada's steel products. ArcelorMittal Dofasco remains a cornerstone of heavy manufacturing employment, and National Steel Car — North America's leader in freight and passenger rail car production — is based in Hamilton. Steel manufacturing and heavy industrial production together create one of the most demanding health and safety compliance environments in Ontario.

OHSA sector-specific regulations for industrial establishments:

The Industrial Establishments Regulation (Ontario Regulation 851) applies to manufacturing, processing, and industrial workplaces in Hamilton. Key requirements include:

Machine guarding: All parts of a machine that may be dangerous to workers must be equipped with a guard or other protective device
Lockout/tagout procedures: Energy control procedures for maintenance and repair of equipment
Confined space entry: Specific protocols including testing, rescue plans, and attendant requirements
Personal protective equipment: Appropriate PPE for identified hazards including steel-toed footwear, hard hats, hearing protection, and respiratory protection
Noise exposure: Ontario has specific noise regulations requiring hearing conservation programmes at 85 dB(A) exposure levels
Workplace transportation: Fork-lift trucks, overhead cranes, and industrial vehicles require operator training and specific safety systems

Green Steel transition: Hamilton is a national leader in Green Steel production, with investments in electric arc furnace technology reducing carbon emissions from steelmaking. New processes and technologies create evolving health and safety requirements — including new chemical exposures, different energy systems, and changed maintenance procedures — that require updated risk assessments and training.

Health and Safety Audits for Hamilton manufacturers: Annual independent audits of management systems, documentation, equipment inspection records, JHSC effectiveness, and incident investigation quality provide the assurance that Hamilton's major industrial employers require to demonstrate due diligence to the MLITSD, WSIB, and major clients.

6. Healthcare in Hamilton: Ontario's Second Largest Hospital Network

Hamilton Health Sciences is the largest employer in the Hamilton region, with approximately 18,000 staff, physicians, and volunteers. Combined with St. Joseph's Healthcare Hamilton, the city operates the second largest hospital network in Ontario. Healthcare is one of Ontario's highest-risk sectors for workplace injuries — particularly musculoskeletal injuries from patient handling and violence from patients.

Healthcare-specific OHSA requirements:

Workplace Violence and Harassment: Ontario's Bill 168 amendments to the OHSA introduced specific requirements for workplace violence and harassment prevention. Healthcare employers must: - Assess the risk of workplace violence and develop measures to control those risks - Implement a written workplace violence policy reviewed annually - Implement measures to protect workers from workplace violence - Establish procedures for summoning assistance when violence occurs or is threatened - Advise workers with information about persons with a history of violent behaviour

In healthcare settings, this is particularly critical. Hamilton's hospital networks treat patients with conditions that can create violent behaviour, including dementia, mental health crises, and substance withdrawal — creating documented and significant violence and aggression risks for frontline clinical staff.

Healthcare sector OHSA regulations: The Health Care and Residential Facilities Regulation (Ontario Regulation 67/93) applies to hospitals, nursing homes, homes for the aged, and similar facilities in Hamilton. It covers ergonomic hazards, patient-handling equipment, and specific lifting and transfer requirements.

WHMIS in healthcare: The Workplace Hazardous Materials Information System (WHMIS) requires hazard identification, labelling, and safety data sheet (SDS) provision for all hazardous materials used in Hamilton healthcare facilities — including disinfectants, sterilants, and laboratory chemicals.

McMaster University and life sciences: McMaster University's research facilities, including the McMaster Immunology Research Centre, create specific biological agent and laboratory safety obligations under the OHSA's regulations for biological and chemical substances.

7. Construction in Hamilton: A Booming Sector With Specific Requirements

In 2025, Hamilton recorded an estimated $2.30 billion in building permit construction value — one of the strongest years in the city's history, representing a 47.3% increase over 2024. Hamilton's construction sector is executing major residential projects, light-rail transit development, the redevelopment of Stelco's former waterfront land, and significant commercial and industrial development.

Ontario's Construction Projects Regulation: The Construction Projects Regulation (Ontario Regulation 213/91) is one of the most detailed sector-specific regulations under the OHSA and applies to all construction work in Ontario including Hamilton. Key requirements include:

Constructor and employer responsibilities: A "constructor" is the entity that undertakes a construction project on behalf of the owner. Constructors carry specific OHSA duties to ensure that the OHSA and its regulations are complied with on the project, including ensuring that all employers and workers on the project comply.

Notice of project: Constructors must notify the Ministry of Labour when a project meets notification thresholds — specifically projects that are expected to take more than three months and that involve 20 or more workers concurrently, or projects that involve certain hazardous work types.

Working at heights: Ontario has specific working at heights requirements including mandatory training for workers on construction projects who may use fall protection. Training must be completed through a Ministry of Labour-approved provider and be renewed every three years.

AED requirements on construction sites: Under the Working for Workers Seven Act 2025, construction projects expected to last three months or more and employing 20 or more workers must have AEDs on site — effective from the date of Royal Assent (November 27, 2025).

WSIB registration and reporting: All construction employers in Hamilton must register with the WSIB and report all workplace injuries and occupational illnesses, including musculoskeletal injuries, falls from height, and struck-by incidents.

8. Food Processing in Hamilton: A Rapidly Growing Sector

Food processing is Hamilton's second largest industry after steel manufacturing. Major Canadian food brands including Maple Leaf Foods, Bunge (Canada's largest canola processor, with a Hamilton plant), and Tim Hortons (first franchise opened in Hamilton in 1964) have significant operations in the region.

OHSA requirements for Hamilton food processors:

Industrial Establishments Regulation: Food processing operations in Hamilton fall within the Industrial Establishments Regulation, requiring compliance with guarding requirements for processing machinery, hygiene provisions, and general industrial safety standards.

WHMIS: Food processing uses a wide range of chemical cleaning agents, sanitisers, refrigerants, and food additives that require WHMIS classification, labelling, safety data sheet provision, and worker training.

Cold chain and refrigeration: Hamilton's cold storage and refrigeration operations — supporting both food processing and the Hamilton Port Authority's cargo handling — create specific health and safety obligations around refrigerant gas exposure, cold stress, and food-grade equipment maintenance.

Ergonomics and musculoskeletal health: Repetitive work on food processing lines — cutting, trimming, packing, and portioning — creates significant musculoskeletal disorder risk. Ontario does not have a standalone ergonomics regulation, but the general duty clause of the OHSA requires employers to take reasonable precautions to protect workers from ergonomic hazards.

9. Health and Safety Policy and Programme Requirements for Hamilton Employers

Ontario's OHSA creates specific written programme and policy requirements that differ in structure from the UK's health and safety policy framework, and that Hamilton businesses must understand.

Health and safety policy (six or more workers): In workplaces in which more than five workers are regularly employed, employers must prepare a written occupational health and safety policy, review that policy at least once a year, and set up and maintain a programme to implement it. This must be posted where workers will most likely see it.

Occupational health and safety programme: An OHS Prevention Programme is required when there are six or more employees. This programme details how the health and safety policy will be implemented, and is specific to each workplace's hazards and risks. Ontario's government provides a Safety Plan Builder to help Hamilton employers identify risks and create a customised plan.

OHSA posting requirements: A copy of the OHSA itself — along with explanatory material from the Ministry of Labour outlining the rights, responsibilities, and duties of workers — must be posted in the workplace in both English and the majority language of the workplace. This is a specific obligation with no direct UK equivalent.

How this differs from UK requirements: The UK's written health and safety policy under Section 2(3) of the Health and Safety at Work Act 1974 is required for employers with five or more employees. Ontario's threshold is six workers. Ontario's requirement to post the legislation itself in the workplace is distinct from UK practice. The requirement for a specific Implementation Programme alongside the policy is more prescriptive than the UK's equivalent.

Health and Safety Consultants and Software solutions help Hamilton businesses maintain and manage their required health and safety policies and programmes, schedule annual reviews, track employee acknowledgements, and produce the documentation that MLITSD inspectors require.

10. Mandatory Health and Safety Training in Ontario

Ontario's OHSA and its regulations impose specific mandatory training requirements that Hamilton employers must fulfil. Failure to provide required training can result in Ministry of Labour orders, fines, or stop-work notices.

Worker Health and Safety Awareness Training: All workers in Ontario must complete a Worker Health and Safety Awareness training course before beginning work. The Ontario government has developed a standard course covering OHSA rights and duties, workplace hazards, and the Internal Responsibility System.

Supervisor Health and Safety Awareness Training: All supervisors in Ontario must complete a Supervisor Health and Safety Awareness training course within one week of commencing the role.

Working at Heights Training (construction): Workers on Ontario construction projects who may use fall protection equipment must complete Ministry of Labour-approved Working at Heights training before performing that work. This training must be renewed every three years.

WHMIS Training: Workers who work with or may be exposed to hazardous materials must receive WHMIS training covering the labelling system, safety data sheets, and safe handling of hazardous materials in their specific workplace.

JHSC Certification: At least two members of every JHSC must complete Basic Certification training and Workplace-Specific Hazard Training through Ministry of Labour-approved trainers.

Workplace Violence and Harassment Training: Employers must provide instruction to workers about the contents of the workplace violence and harassment policies and programmes.

Training records must demonstrate who was trained, on which topics, when, and through which approved provider. These records are requested by MLITSD inspectors during compliance visits and are essential evidence of due diligence in the event of a workplace incident.

Health and safety training programmes designed for Hamilton businesses must align with Ontario's specific mandatory training requirements — not simply adopt UK or European training frameworks without adaptation.

11. International Businesses With Hamilton Operations: Cross-Border Compliance Considerations

Hamilton's position in the Golden Horseshoe — the most highly industrialised region in Canada — makes it a significant destination for international business investment. ArcelorMittal Dofasco's operations represent one of the most prominent examples: a subsidiary of Arcelor Mittal, the world's largest steel producer, operating within Ontario's provincial regulatory framework.

UK and European businesses with Hamilton operations: UK and European employers who establish operations in Hamilton — whether manufacturing, distribution, healthcare research, or technology ventures linked to McMaster Innovation Park — must comply with Ontario's OHSA, not UK or European health and safety law. The frameworks differ in fundamental ways:

Dimension	UK (HSWA 1974 / MHSWR 1999)	Ontario (OHSA)
Primary legislation	Health and Safety at Work Act 1974	Occupational Health and Safety Act
Enforcement body	HSE	Ministry of Labour, Immigration, Training and Skills Development (MLITSD)
Worker compensation	Employers' Liability Insurance	WSIB (Workplace Safety and Insurance Board)
Worker participation	Safety Representatives (union) / Elected Representatives	Joint Health and Safety Committees (JHSC)
JHSC threshold	Safety committees on request (2+ safety reps)	Mandatory for 20+ workers
Mandatory training	MHSWR Regulation 13 general duty	Specific mandatory courses (Awareness, WHMIS, Working at Heights)
Administrative penalties	Fee for Intervention (£174/hour)	New administrative penalty scheme (from Jan 2026)
Maximum corporate fine	Unlimited (prosecution)	$1.5 million per charge

Hamilton businesses with UK or European offices: The reverse consideration applies equally. Hamilton businesses that establish or maintain operations in the UK, Netherlands, France, Germany, or elsewhere in Europe must comply with the local health and safety framework in each jurisdiction:

UK: Health and Safety at Work Act 1974, MHSWR 1999
Netherlands: RI&E risk assessment, arbodienst obligation
France: DUERP risk assessment, PAPRIPACT programme
Germany: DGUV regulations, Gefährdungsbeurteilung
Italy: RSPP requirements, DVR documentation

Global Health and Safety Consultants and International Health and Safety Consultants help businesses navigate these cross-border obligations — whether for a Hamilton manufacturer expanding to European markets or a UK business establishing Ontario operations.

12. What to Look for in Health and Safety Consultants Serving Hamilton, Ontario

Hamilton businesses engaging health and safety consultants need assurance of competence in Ontario's specific legislative framework, sector knowledge relevant to the city's economy, and professional credentials that withstand MLITSD scrutiny.

Key criteria for evaluating Hamilton health and safety consultants:

Ontario and Canadian regulatory expertise: Consultants must have genuine working knowledge of the OHSA and its sector-specific regulations — the Industrial Establishments Regulation, the Construction Projects Regulation, the Health Care and Residential Facilities Regulation, and WHMIS requirements. Generic health and safety knowledge without Ontario-specific expertise is insufficient.

Professional qualifications: In Ontario, the Canadian Registered Safety Professional (CRSP) designation from the Board of Canadian Registered Safety Professionals is the recognised professional credential for health and safety practitioners. The CRSP requires demonstrated experience, education, and ongoing professional development. Consultants with CRSP designation carry professional accountability comparable to CMIOSH-level practitioners in the UK.

JHSC expertise: Understanding the JHSC requirements under OHSA — including certification requirements, quarterly inspection obligations, and the right to investigate accidents — is fundamental for consultants serving Hamilton's workforce.

Sector-specific experience: Hamilton's dominant sectors — steel and heavy manufacturing, healthcare, construction, food processing — each carry distinct regulatory requirements. Verify that consultants have specific experience with OHSA compliance in the sectors relevant to your operations.

WSIB familiarity: Ontario's WSIB creates reporting, premium, and return-to-work obligations that are integral to health and safety management in Hamilton. Consultants should understand WSIB requirements and how effective safety management directly affects premium rates.

Technology integration: Health and Safety Consultants and Software solutions that support OHSA-compliant documentation, training records, JHSC meeting records, and workplace inspection programmes make compliance management efficient and auditable — critical for Hamilton's smaller employers who cannot sustain complex manual systems.

International capability: For Hamilton businesses with international operations or for international businesses establishing Hamilton presence, cross-border expertise in UK, European, and US health and safety frameworks enables coordinated compliance management across all locations.

Frequently Asked Questions

What is Ontario's OHSA and how does it apply to Hamilton businesses?

The Occupational Health and Safety Act (OHSA) is Ontario's foundational workplace health and safety legislation, applying to most workers, supervisors, employers, and workplaces in Ontario, including all of Hamilton's industries. It sets out duties for employers, supervisors, and workers, establishes measures for dealing with workplace hazards, and provides for enforcement by the Ministry of Labour, Immigration, Training and Skills Development (MLITSD).

What changed under Ontario's Working for Workers Seven Act 2025?

Key changes include a new administrative penalty scheme allowing MLITSD inspectors to issue financial penalties without prosecution (effective January 2026), mandatory AEDs on qualifying construction sites, WSIB reimbursement for defibrillator costs, and recognition of accredited health and safety management systems as equivalents under the OHSA.

When is a Joint Health and Safety Committee (JHSC) required in Hamilton?

A JHSC is mandatory when there are 20 or more regularly employed workers. A Health and Safety Representative is required for workplaces with six to 19 workers. At least two JHSC members must complete Ministry of Labour-approved certification training.

What are the maximum OHSA penalties for Hamilton employers?

The maximum corporate fine is $1,500,000 per charge. The maximum fine for an individual is $100,000 and/or imprisonment for up to 12 months. From January 2026, administrative penalties can also be issued without prosecution.

What mandatory training do Hamilton employers need to provide?

All workers must complete Worker Health and Safety Awareness training. All supervisors must complete Supervisor Health and Safety Awareness training within one week of assuming the role. Construction workers using fall protection must complete Ministry-approved Working at Heights training, renewed every three years. Workers exposed to hazardous materials must complete WHMIS training. JHSC members must complete certification training through an approved provider.

How does Ontario's OHSA differ from UK health and safety law?

Key differences include Ontario's mandatory JHSC structure (UK has optional safety committees), Ontario's administrative penalty scheme from 2026, WSIB (workers' compensation) obligations with no direct UK equivalent, specific mandatory awareness training courses for all workers and supervisors, and a $1.5 million maximum corporate fine versus the UK's unlimited prosecution fine. Federally regulated Hamilton workplaces (rail, ports, federal operations) fall under Part II of the Canada Labour Code rather than the OHSA.
