When Does Your Workplace Legally Require a Health and Safety Committee or Representative? The answer depends on the health and safety committee requirements in the province where the work is performed, the number of workers regularly employed at the workplace or work site, the duration of the work, and sometimes the industry or direction of the regulator.
Employers shouldn’t rely only on their total company headcount. A business with 40 employees divided among several locations may have different obligations than a single workplace with 40 regularly employed workers.
A joint health and safety committee is a formal worker-employer group that helps identify hazards, review health and safety concerns, recommend improvements, and support worker participation in the workplace safety system.
A committee normally includes worker members who don’t exercise managerial functions and employer representatives. Depending on the jurisdiction, committee duties may include workplace inspections, incident investigations, reviewing worker concerns, making recommendations, and monitoring health and safety programs.
A health and safety representative performs a similar worker-participation role in a smaller workplace where a full committee isn’t required. The exact duties, selection process, training, and record requirements differ among provinces.
Employers can begin by asking four questions:
In general:
Alberta requires an employer to establish a health and safety committee when it has 20 or more regularly employed workers and to designate a health and safety representative when it has five to 19 regularly employed workers. (Alberta.ca)
British Columbia generally requires a joint health and safety committee where 20 or more workers are employed at a workplace for longer than one month. A worker health and safety representative is generally required where more than nine but fewer than 20 workers are employed for longer than one month. WorkSafeBC may also order a committee in another workplace. (WorkSafeBC)
Saskatchewan generally requires an occupational health committee at a workplace with 10 or more workers. A representative is required at a prescribed workplace with five to nine workers. (Government of Saskatchewan)
These are starting points, not a substitute for reviewing the current legislation that applies to the specific workplace.
Alberta OHS committee requirements are based on the number of regularly employed workers connected to the employer and work site. An employer with 20 or more regularly employed workers must establish a health and safety committee, while an employer with five to 19 regularly employed workers must designate a health and safety representative. (Alberta.ca)
Alberta also has specific rules for multi-employer work sites. Where there is no prime contractor, employers may need to coordinate a site-based committee or representative if the worker thresholds are reached. Where a prime contractor has been designated, a site-based committee or representative may not be required in the same way, but the prime contractor must coordinate health and safety issues and designate a person to support cooperation between employers and workers. (Alberta.ca)
The worker members of an Alberta joint health and safety committee must generally be selected by the workers they represent or by the applicable union. A committee must have two co-chairs, with one selected by employer representatives and the other by worker members.
Alberta committees must also have written terms of reference addressing matters such as member selection, terms of office, meeting frequency, records, concerns, dispute resolution, and replacement of members. Employers must ensure committee members and representatives receive training on their roles, work-site party obligations, and worker rights. (Search OHS Laws)
WorkSafeBC joint committee requirements generally apply when a workplace has 20 or more workers employed for longer than one month. A worker health and safety representative is generally required when a workplace has 10 to 19 workers employed for longer than one month. (WorkSafeBC)
This makes the workplace count particularly important. A company may employ hundreds of workers across British Columbia, but the employer still needs to determine how workers are distributed among individual workplaces and how long those workplaces operate.
Worker representatives on a British Columbia joint committee must be selected from workers who don’t exercise managerial functions. Employer representatives are selected by the employer, and the committee structure must provide appropriate representation from both sides.
Joint committees have defined functions, including identifying unsafe conditions, dealing with complaints, consulting with workers and the employer, making recommendations, advising on programs and workplace changes, and participating in inspections and investigations. A worker representative has similar duties to the extent practicable. (WorkSafeBC)
British Columbia also has specific workplace safety committee training requirements. New joint committee members generally require eight hours of instruction, while worker health and safety representatives generally require four hours. Committee members and representatives are also entitled to annual educational leave for occupational health and safety training. (WorkSafeBC)
WorkSafeBC requires an annual written evaluation of a joint committee’s effectiveness. This means employers should assess whether the committee is meeting its legal responsibilities and producing meaningful workplace improvements rather than merely holding meetings. (WorkSafeBC)
A Saskatchewan occupational health committee is generally required at a workplace with 10 or more workers. Where a workplace has five to nine workers and performs work prescribed as highly hazardous, the employer is generally required to appoint an occupational health and safety representative. (Government of Saskatchewan)
A Saskatchewan committee must have between two and 12 members. At least half must be workers who aren’t involved in management, and employer members can’t outnumber worker members. Non-union workers elect their representatives, while unionized workplaces follow the applicable union selection process. (Government of Saskatchewan)
The committee has two co-chairs. One is selected by the employer members, and the other is selected by worker members.
Saskatchewan occupational health committees help identify and control hazards, review worker concerns, conduct inspections, investigate reportable incidents, investigate work refusals, and support health and safety programs and training. Employers must consult and cooperate with the committee and respond to concerns or recommendations. Where a hazard isn’t corrected, the employer must provide reasons for not taking action. (Government of Saskatchewan)
Employers must ensure committee co-chairs are trained in the duties and functions of committee members. Committee members may also be entitled to education leave for occupational health and safety training. (Government of Saskatchewan)
One of the most common errors is counting every employee in the company and applying that number to every location.
Consider a contractor with 32 employees. Eight work in the office, six work in a fabrication shop, and the remaining employees rotate among short-term projects. The employer can’t simply conclude that one committee covers every location or that each workplace automatically requires one.
The employer needs to examine:
A documented assessment is useful when the workplace structure is complex. It shows how the employer determined which committees or representatives were required and why.
Temporary and mobile operations create recurring problems because staffing levels change. A project may begin with four workers, increase to 24 during peak work, and then fall below the normal threshold.
Employers may also assume a committee at head office automatically represents workers at branches, remote sites, or construction projects. That assumption may not reflect the legislation or the practical needs of workers at those locations.
Other common mistakes include:
Where the answer is unclear, employers should review the current legislation and seek jurisdiction-specific advice.
Committee and representative documentation should demonstrate both legal structure and practical activity.
Useful records may include:
Attendance sheets alone don’t show whether the committee performed its required functions. Records should connect concerns, recommendations, responsibilities, decisions, and follow-up.
The employer remains responsible for providing a healthy and safe workplace. A committee or representative supports the internal responsibility system but doesn’t take over management’s legal duties.
Supervisors should communicate hazards, cooperate with inspections and investigations, respond to concerns, and help implement corrective actions. They should understand how committee recommendations affect the work they oversee.
Workers should know who represents them, how to submit concerns, and how to participate in committee activities. Worker members need enough time, information, training, and access to the workplace to perform their responsibilities effectively.
COR and SECOR requirements are separate from provincial legislation. An audit may examine whether the employer identified its committee or representative obligations, provided training, maintained records, communicated minutes, responded to recommendations, and involved workers in inspections or investigations.
Certification requirements don’t replace Alberta, British Columbia, or Saskatchewan law. A company can have well-organized COR safety documentation and still misunderstand a provincial committee requirement.
Industry best practice may also exceed the legal minimum. An employer may establish a worker participation group even when a formal committee isn’t legally required, particularly where work is remote, higher-risk, or operationally complex.
Missing a committee or representative requirement can create regulatory exposure and weaken evidence of due diligence. It may also limit worker participation, delay hazard reporting, and allow concerns to remain unresolved until they contribute to an incident or operational interruption.
Poor committee structure can affect WCB or claims performance, productivity, corrective-action costs, contractor prequalification, client expectations, COR or SECOR performance, and audit readiness. A committee that functions well can identify problems earlier, improve communication, and help management make better-informed decisions.
Situation: A regional employer had 38 workers spread among an office, two shops, and several temporary projects. Management assumed one committee at the main office met all provincial requirements.
Action: The employer reviewed worker counts, project duration, provincial jurisdiction, and the structure of each workplace. It established the required worker participation arrangements, documented member selection, provided training, and created a process for recommendations and employer responses.
Result: Workers had clearer representation, committee records became more reliable, and management gained a stronger process for inspections, concerns, investigations, and corrective-action follow-up.

Health and safety committee requirements are established by provincial, territorial, or federal legislation rather than one national rule. The requirement may depend on the number of workers at a workplace, how long the work continues, the industry, and whether the regulator directs the employer to establish a committee.
Not always. Employers may need to assess each workplace or work site separately because workers can be divided among offices, shops, projects, branches, and temporary locations. A documented review of staffing levels, jurisdiction, work duration, and workplace structure can help support the employer’s decision.
A joint health and safety committee includes both worker and employer members who participate in workplace health and safety activities. A health and safety representative usually performs a similar worker-participation role at a smaller workplace where a full committee isn’t required.
Alberta generally requires a health and safety committee where an employer has 20 or more regularly employed workers and a representative where it has five to 19 regularly employed workers. Multi-employer work sites, prime contractor arrangements, and other workplace circumstances may affect how the requirement applies.
British Columbia generally requires a joint health and safety committee where 20 or more workers are employed at a workplace for longer than one month. A worker health and safety representative is generally required where 10 to 19 workers are employed for longer than one month, although WorkSafeBC may direct other workplaces to establish a committee.
Saskatchewan generally requires an occupational health committee at a workplace with 10 or more workers. A representative is generally required at certain prescribed high-hazard workplaces with five to nine workers, so employers should confirm whether their work falls within a prescribed category.
