No national rulebook: How OHS inspections are triggered across Canada

The compliance reality multi-plant operators can't ignore:

There's no national list to check yourself against

Workplace health and safety in Canada isn't regulated federally. Every province and territory runs its own OHS act, its own regulator, and its own enforcement priorities.

That means there's no single national list a multi-plant operator can check itself against. What is consistent across provinces is the method: most provincial regulators have moved to risk-based inspection targeting, using injury and illness rates, incident frequency, and compliance history to decide where to focus, rather than inspecting on a fixed, predictable rotation.

What that looks like in three provinces

ONTARIO

Ontario's Ministry of Labour, Immigration, Training and Skills Development selects sectors and workplaces for its compliance campaigns using injury, illness, and fatality rates, compliance history, the nature of the work, and field intelligence from inspectors. Its 2025–2026 campaign schedule names wood and metal fabrication specifically as priority areas within the industrial sector.

ALBERTA

Alberta runs a parallel, independently-set process: its OHS Proactive Inspection Program directs inspection activity toward worksites and sectors with:

high injury and illness rates
high incident frequency with low compliance
among its focus areas, explicitly names manufacturing subsectors: steel and metal products, welding and wood products.

QUÉBEC

Quebec's CNESST takes a related but distinct approach: rather than naming sectors, it sets annual priority hazard categories directly from injury-cause data.

Its five predominant hazard categories account for roughly 70% of the injuries it treats, under a multi-year prevention-inspection plan.

OVERALL

None of the three provinces publishes a list of the specific workplaces it plans to inspect; each applies the same underlying idea, independently of the others.

What that means for a multi-plant, multi-province operations

For an EHS Director accountable across 100 to 500+ contractors and multiple plants (often spanning more than one province) that risk-based model means there's no list to check your specific facility against and breathe easy if you're not on it.

Selection criteria and sector priorities shift year to year and province to province, and "we weren't named this year" is not a strategy. It's a bet, and one that gets harder to win the more provinces you operate in.

Key takeaways

The real exposure isn't the campaign

Strip away any single province's campaign name and the real exposure is constant everywhere you operate: whether a clean audit trail exists for every contractor, at every plant, in every province, the day an inspector actually asks for it. That's the standard every provincial OHS regime (not just Ontario's, Alberta's, or Quebec's) holds the personally accountable EHS Director to.

If this year's campaign happens to name your sector, in whichever province it runs, would your current process hold up on day one or would you be building the answer while the inspector waits?
