Who Regulates Workplace Health & Safety in Canada?

Which regulator applies to your business?

The test is your industry, not your location or size. Federal jurisdiction under the Canada Labour Code Part II — enforced by Employment and Social Development Canada's (ESDC) Labour Program — applies only to federally regulated sectors:

• Banks and federal credit unions
• Telecommunications and broadcasting
• Interprovincial and international transportation (trucking, rail, air, marine)
• The federal public service and Crown corporations

Everyone else falls under provincial or territorial law. A construction company in Mississauga answers to Ontario's MLITSD. The same company running trucks between Ontario and Manitoba is federally regulated for that trucking operation. Some businesses genuinely straddle both regimes, which is why the first step of any compliance program is confirming jurisdiction.

The 14 regulators, by jurisdiction

Provinces reorganize and rename their labour departments regularly, so the branded names below are current as of mid-2026 — but the enforcement mandate stays the same through renames.

What OHS regulators can actually do

The powers are broadly consistent across all 14 jurisdictions. Inspectors can:

• Enter a workplace without a warrant or advance notice. Inspections can be proactive (scheduled campaigns), reactive (after an incident or complaint), or part of a targeted enforcement blitz.
• Review documents and training records, interview workers, and take samples and photos.
• Issue compliance orders and stop-work orders on the spot. A stop-work order halts the affected operation until the hazard is corrected.
• Issue tickets and prosecute. In Ontario, corporate fines under the OHSA can reach $2,000,000 per conviction, and individual supervisors and directors can be fined or jailed. Other provinces carry comparable penalty ceilings.

Most regulators also publish their enforcement priorities in advance. Ontario's MLITSD, for example, announces annual inspection campaigns targeting specific hazards and sectors — we cover the current cycle in our MLITSD inspection blitz guide.

Where COR fits: accreditation is not regulation

COR (Certificate of Recognition) is often confused with a government requirement. It isn't one. COR is an industry accreditation administered by provincial safety associations — the IHSA in Ontario, the ACSA in Alberta, the BCCSA in BC — that certifies your health and safety management system against a national standard.

No regulator forces you to hold COR. But many general contractors, municipalities, and large buyers now require it before you can bid, so for contractors in most provinces it operates as a de facto market-entry requirement. It also demonstrates due diligence if a regulator ever does come through your gate.

We maintain step-by-step COR guides for each jurisdiction: COR certification in Ontario, Alberta, British Columbia, Saskatchewan, Manitoba, New Brunswick, Nova Scotia, Newfoundland & Labrador, and Northern Canada.

Staying compliant, wherever you operate

If you operate in one province, compliance means knowing one act, one set of regulations, and one inspectorate's priorities. If you operate across provinces — or run a federally regulated operation alongside provincial ones — you need a program that maps each site to the right regulator and keeps training, documentation, and hazard assessments aligned to each.

That mapping exercise is a standard part of our safety consulting services: confirming jurisdiction, closing the gaps each regulator would flag, and building the documentation an inspector (or COR auditor) expects to see.
