Alberta Health and Safety Program Requirements: The Worker-Count Thresholds Explained
Alberta employers often mix together three different questions: when a formal health and safety program is legally required, when a health and safety representative or committee is required, and whether COR or SECOR applies. They are related, but they are not the same threshold.
5 to 19 workers
Health & Safety Representative
Alberta requires a health and safety representative when an employer regularly employs 5 to 19 workers, subject to the legislation and worksite rules.
20+ workers
Health & Safety Committee
Alberta requires a joint health and safety committee when an employer regularly employs 20 or more workers, subject to the legislation and worksite rules.
20+ workers
Health & Safety Program
Alberta requires an employer who regularly employs 20 or more workers to establish and implement a health and safety program, unless otherwise directed under the Act.
This is separate from COR and SECOR eligibility.
Alberta's COR program currently describes SECOR for businesses with up to 10 employees and standard COR for businesses with 10 or more employees. The 20-worker legal health and safety program threshold should not be used as the COR/SECOR dividing line.
Does a Business With Fewer Than 20 Workers Still Need Safety Processes?
Yes. The 20-worker threshold determines when the Act specifically requires a formal health and safety program. It does not eliminate the employer's broader OHS responsibilities below that threshold. Alberta's guidance identifies employer responsibilities such as protecting worker health and safety, providing competent supervision, identifying hazards, providing training, using safe work practices, and investigating certain incidents.
Smaller employers may therefore need many of the same practical processes even when the formal program requirement in section 16 does not apply. COR or SECOR participation can add another set of management-system expectations on top of the underlying legal duties.
Alberta Does Not Prescribe One Universal Program Template
Alberta's health and safety program guidance states that there are no mandatory universal program elements under OHS legislation and that employers have flexibility to develop programs suited to their workplace. Mandatory legal requirements still apply, and items such as hazard assessment, worker participation, and training can form part of the program.
That flexibility is useful, but it also means a generic safety manual is not automatically a compliant or effective program. The system should reflect the employer's hazards, roles, work locations, workforce, contractors, equipment, and operating processes.
A Practical Program Review Should Ask
- Are the employer's actual hazards identified and controlled?
- Are workers and supervisors clear on their responsibilities?
- Are required worker participation mechanisms in place for the workforce size and worksite structure?
- Can the employer demonstrate training, competency, inspections, incident follow-up, and corrective action where required?
- Do contractor and multi-employer worksite arrangements reflect the work that actually occurs?
- Does the written program match what supervisors and workers do in practice?
Quick Threshold Reference
Worker-count rules can depend on how workers and worksites are counted and whether multiple employers or a prime contractor are involved. Confirm the current legal requirements for your specific worksite structure.
