Health and Safety in Canada: 12 Duties a UK or US Parent Gets Wrong

A UK group opens a Toronto office, then adds Vancouver, then Montreal. Somebody asks the group health and safety lead to confirm Canadian compliance. They search for the Canadian equivalent of the Health and Safety at Work Act, find the Canada Labour Code, read Part II and report back that the position is understood.

It is not. For almost every commercial employer in Canada, the federal Code does not apply at all.

That one structural fact causes more wasted effort and more real exposure than any individual duty, and it is the first of twelve things a foreign parent reliably gets wrong. None is difficult once seen. All are invisible if you assume Canada works like the UK or like a single federal jurisdiction.

1. Occupational health and safety is provincial, not federal

The Canada Labour Code governs occupational health and safety only for federally regulated work: interprovincial transport, telecommunications, air and rail, federally regulated banking, and similar. Everything else, which means the overwhelming majority of offices, falls to the province or territory.

So a Toronto office is governed by Ontario's Occupational Health and Safety Act, a Vancouver office by British Columbia's regime administered by WorkSafeBC, a Calgary office by Alberta's and a Montreal office by Quebec's. The Canadian Centre for Occupational Health and Safety maintains the map of which legislation applies where.

Determine your jurisdiction before anything else. A group policy drafted against the federal Code for a provincially regulated office is well-intentioned and irrelevant.

2. The internal responsibility system is the organising idea

Canadian OHS is built on a philosophy with a name, and understanding it explains why the duties look the way they do.

The internal responsibility system holds that everyone in the workplace, from the employer through supervisors to individual workers, has defined responsibilities, and that the workplace parties are expected to identify and resolve issues themselves rather than waiting for a regulator. UK law allocates duties too, but the Canadian framing is more explicit, more symmetrical and more procedural, and it is why committees, rights to refuse and supervisor duties carry the weight they do.

3. You will need a committee or a representative

Thresholds differ by province, but the pattern is consistent: above a small headcount a health and safety representative is required, and above a larger one a joint health and safety committee with worker and employer members.

These are not discussion forums. Committees have inspection functions, meeting frequency requirements, and the right to make written recommendations that the employer must respond to in writing within a defined period. The CCOHS overview of health and safety committees sets out the common structure. Ontario's official guide to the OHSA explains the provincial detail.

The part foreign parents miss is the written response obligation. A committee recommendation that receives no documented reply is a breach independent of whatever the recommendation was about.

4. Certified members are a trained, named role

In several provinces, committee members must include certified members who have completed prescribed training. This is not a general awareness course; it is a defined certification with a syllabus set by the regulator.

Groups that constitute a committee from volunteers and then discover the certification requirement lose months. Build it into the plan, and budget for replacement when a certified member leaves, because the obligation attaches to the committee rather than to the individual.

5. Workers have a statutory right to refuse unsafe work

There is no close UK equivalent, and this is the duty most likely to surprise a British or American manager in real time.

Provincial legislation gives a worker the right to refuse work they have reason to believe is likely to endanger themselves or another worker, and it prescribes what follows: the worker reports to the employer or supervisor, an investigation takes place in the worker's presence and usually with a committee member, and if unresolved the regulator is notified and investigates. The worker is not to be disciplined for exercising the right.

Managers need to know the procedure exists before it is invoked, because improvising a response is where the reprisal complaint comes from rather than from the original hazard.

6. Due diligence is the defence, and it is evidential

Canadian OHS prosecutions turn on due diligence: whether the employer took all reasonable care in the circumstances. That is close in spirit to reasonable practicability, with one practical difference. Because the defence is the central battleground, Canadian practice places unusually heavy weight on contemporaneous evidence.

Written hazard assessments, training records with dates and signatures, inspection reports, committee minutes, corrective actions with completion evidence. A group that manages compliance through a well-run system has the defence available. One that manages it through capable people does not, because the defence is documentary.

7. Supervisors carry personal statutory duties

Provincial acts impose duties directly on supervisors, not only on the employer, and they include ensuring workers comply with the legislation, advising workers of hazards, and providing written instructions where prescribed.

The term used for the role of overseeing particular work is defined in statute, which makes it narrower than the general UK notion of a competent person. Check that the people your organisation chart calls managers meet the statutory definition where the legislation requires one.

8. WHMIS has supplier, workplace and training limbs

Canada's hazardous products system is aligned to the global harmonised classification, which makes the labels and safety data sheets look familiar to anyone who works with European equivalents. The duties are not identical.

WHMIS requires supplier labels and data sheets, workplace labels where a product is decanted or transferred, data sheet access for workers, and worker education and training that is specific to the products present. For an office the inventory is small, usually cleaning products and some maintenance materials, but the training duty is not reduced in proportion to the inventory.

9. Workplace violence and harassment need written programmes

Ontario in particular requires employers to have policies and written programmes addressing workplace violence and workplace harassment, with procedures for reporting, investigation and outcomes, reviewed on a cycle.

This is the duty where a global policy most often falls short, not because its values are wrong but because the Canadian requirement is procedural. It specifies that a programme exists, that incidents are investigated appropriately, and that workers are informed of the results. A statement of principle is not a programme.

10. Reporting obligations differ by province and by severity

Each jurisdiction defines what must be reported, to whom and how fast, with separate categories for serious or critical injuries, fatalities, and occupational illness, and separate notification to the workers' compensation authority.

A group incident taxonomy built around UK reporting thresholds will not map. Build the Canadian categories in as their own fields rather than deriving them from a UK classification, or the first serious incident will produce a late notification.

11. Three Canadian offices means three regimes

The point worth repeating because it is counterintuitive to a European reader. Ontario, British Columbia and Quebec are not regional variations of one national system. They have separate statutes, separate regulators, separate committee thresholds, separate training requirements and, in Quebec, a different working language for your documentation.

A single Canadian policy is achievable as a framework. A single set of Canadian arrangements is not.

12. Directors and officers can be personally liable

Provincial legislation imposes duties on directors and officers of corporations to take all reasonable care to ensure the corporation complies, and liability is personal rather than only corporate.

For a UK or US parent this reaches the people who sit on the Canadian subsidiary's board, who are frequently group executives appointed for governance reasons and who may never have visited the office. They need to be able to describe how they satisfy themselves that compliance is in place, which is a reporting question for the group rather than a local one.

The twelve at a glance

Duty	Where it bites	The foreign-parent error
Provincial jurisdiction	Every non-federal employer	Reading the federal Code and stopping
Internal responsibility system	The whole framework	Treating duties as employer-only
Committee or representative	Above provincial thresholds	No written response to recommendations
Certified members	Several provinces	Committee formed before training planned
Right to refuse	Any worker, any time	Managers improvise, reprisal complaint follows
Due diligence defence	Prosecution and enforcement	Capable people, no contemporaneous records
Supervisor duties	Named individuals	Job titles assumed to satisfy the statute
WHMIS	Any product on site	Small inventory treated as no training duty
Violence and harassment	Written programme required	Global policy statement offered instead
Reporting	Each province, each category	UK thresholds mapped across
Multi-province footprint	Toronto plus Vancouver plus Montreal	One Canadian answer assumed
Director liability	Subsidiary board members	Group appointees with no line of sight

Count the rows you could evidence today. Most groups manage three or four, and almost always the same ones: they have a policy, they have a committee, and they have nothing written down about the other ten.

Making Canada part of a group system

The workable pattern holds everywhere: one methodology, one register, and the local statutory requirement attached to each line with the province recorded alongside the country.

That matters more in Canada than most places precisely because the due diligence defence is documentary. A system holding the hazard assessment, the dated training record, the committee minute, the recommendation and the written response is the defence itself, which is where health and safety consultants and software are worth more in combination than either alone. Periodic health and safety audits then verify each site against its own province rather than a group standard.
