Workplace first-aid requirements by province in Canada

There is no single Canadian rule for the number of workplace first aiders, kit size, training level or first-aid room. Choose the law that applies to the employer and worksite, then assess the actual shift size, hazards, distance to medical care and multi-employer arrangements. A business with worksites in two provinces may need two different first-aid plans. A federally regulated workplace may instead fall under federal occupational health and safety rules even though it is physically located in a province.

This guide gives a direct route to each province's current primary source and a practical way to apply it. It deliberately avoids a universal “one first aider per X workers” table: such a table would be wrong for some hazard classes, remote sites, construction projects and newer amendments. Before publishing or using a numeric staffing or kit decision, check the current enacted regulation and regulator guidance for the specific jurisdiction and worksite.

First decide whether federal or provincial rules apply

Employment sector and operation determine jurisdiction, not merely the mailing address. Canada's list of federally regulated industries includes, among others, certain interprovincial trucking, airlines, railways, banks and telecommunications. The federal occupational-health overview points federally regulated workplaces to the Canada Labour Code and federal regulations; most local construction, retail and many service workplaces are provincial or territorial.

Federal first-aid kit rules may change. The Labour Program's 2026–28 forward regulatory plan describes a proposed harmonisation initiative. A proposal is not an enacted requirement. Verify the current Canada Occupational Health and Safety Regulations and sector-specific federal regulations before relying on a kit specification, training-recognition rule or date.

Provincial source directory and decision points

The sources above are starting points. Some regulator pages summarise law, while a linked regulation is controlling. Do not rely on this table to calculate a headcount: open the actual schedule, identify the workplace classification and document the result. Territories have their own laws and regulators; they are not captured by a ten-province table. A territorial worksite needs a separate current-rule review.

What changed recently enough to deserve special care?

British Columbia's amended occupational first-aid requirements took effect in November 2024; the employer's written assessment determines the appropriate services using WorkSafeBC's updated framework. Prince Edward Island also updated its workplace first-aid framework from January 2025, including competent risk assessment and training levels. Nova Scotia consolidated first-aid provisions into its Workplace Health and Safety Regulations. New Brunswick adjusted its training/kit approach. These changes are why old “Canada first aid requirements” charts often fail a current check.

Calculate requirements for a real workplace

1. Confirm legal jurisdiction. Provincial, territorial or federal? Identify the regulator and the exact worksite, including temporary and mobile workplaces.
2. Classify the work. The applicable rule may use low/higher hazard or another classification; document actual tasks and the person who assessed them.
3. Count people by shift. Use the number the regulation requires, not the annual payroll total. Account for subcontractors or volunteers where the local rule includes them.
4. Evaluate location and access to care. Travel time, remoteness, transport, communications and lone work can change the required first aid response.
5. Choose the required first aider and training level. Check approved or recognised training and certificate validity. Schedule coverage for absence, breaks and shifts.
6. Select kit, equipment, room and transport. Use the current local schedule and any CSA standard it incorporates. A CSA-labelled box alone does not prove enough kits, correct placement or a trained attendant.
7. Coordinate multiple employers. A prime/general contractor may have an express role. Where shared provision is permitted, document who supplies it and how every worker obtains prompt help.
8. Post and test the response. People should know who the first aiders are, where supplies are, how to call for help and how a remote worker will be transported.
9. Review on change. A larger shift, new hazard, moved worksite, different access road or amended regulation can change the answer.

Example: two sites, two answers

A company operates a small office in Ontario and a high-hazard remote field crew in British Columbia. The office must apply Ontario Regulation 1101 using the people on the shift and its station/attendant requirements. The B.C. crew needs a WorkSafeBC written first-aid assessment, taking account of the higher-risk work and time to medical care. The company cannot buy one national kit type, appoint one remotely located first aider and assume both worksites are covered. If the field operation is in a federally regulated industry, jurisdiction needs a separate federal review as well. The example shows the method, not the numeric staffing outcome for either site.

Common mistakes

• Using the province of the head office rather than the worksite and employer's legal jurisdiction.
• Counting the total company headcount instead of the relevant shift or site population.
• Ignoring remote access, transport, language, lone work or concurrent contractors.
• Assuming any “Level 1” course is accepted by every province or that an old certificate never needs renewal.
• Buying a CSA-compliant kit without checking the required number, placement, trained people and special hazards.
• Treating a proposed federal rule or regulator guidance summary as an enacted provision.
• Leaving first-aid provision unstaffed during breaks, night shifts or a first aider's absence.

Complys and the product boundary

The observed Complys Canada homepage and pricing page discuss worker training/certifications and compliance records. The proposed /ca/ohs-compliance-software money route in the manifest was not verified live in this writer-side check. Complys must not be described as automatically calculating province-specific first-aid legal requirements, certifying a first aider or providing first aid. After the current product and route are tested, a safe CTA is: Ask Complys to show how its existing Canadian records can store your jurisdiction-specific assessment, first-aider certificates and review dates. The employer remains responsible for the correct local decision.
