Supervisor Health and Safety Awareness in 5 Steps

Yes. Ontario Regulation 297/13, made under the Occupational Health and Safety Act (OHSA), requires every employer to ensure their supervisors complete basic occupational health and safety awareness training. This applies to every supervisor in Ontario regardless of industry, job title, or years of experience. Employers must keep a written record of completion. The legal definition of "supervisor" under the OHSA is broader than most people expect - it includes team leads, lead hands, forepersons, and anyone who directs the work of others, not just those with the formal title.

OHSA Section 27 sets out five specific legal duties for supervisors: ensure workers comply with the Act and regulations; ensure workers use required protective equipment; advise workers of actual or potential hazards; provide written instructions where prescribed; and take every precaution reasonable to protect workers. If a supervisor fails to fulfill these duties and a worker is injured, they can face personal fines of up to $100,000 per offence under OHSA Section 66. Supervisors have been successfully prosecuted even when the employer was also charged - "I didn't know" is not a valid defence under the Act.

Yes. Under Section 217.1 of the Criminal Code of Canada - commonly called the Westray Law - supervisors and employers who show wanton or reckless disregard for worker safety can face criminal prosecution and imprisonment if that disregard causes death or serious bodily harm. This law applies in every province and every industry. It was enacted following the 1992 Westray mine explosion in Nova Scotia that killed 26 workers. Criminal liability is separate from OHSA penalties and applies on top of any provincial fines.

Under OHSA Section 43, a supervisor must follow a defined four-step process. First, go to the work location and investigate with the worker present - take the concern seriously rather than dismissing it. Second, listen to the worker's full explanation before responding. Third, document everything: the date, the nature of the refusal, your findings, and any corrective action taken. If the issue is not resolved, a health and safety representative or JHSC member joins the investigation; if it remains unresolved after that, the Ministry of Labour, Training and Skills Development (MLTSD) is called. Pressuring, threatening, or retaliating against a worker who refuses unsafe work is a separate offence under OHSA Section 50.

Every worker in Ontario has three rights under the OHSA: the right to know about workplace hazards (including WHMIS training and access to Safety Data Sheets), the right to participate in workplace health and safety through a Joint Health and Safety Committee (JHSC) or health and safety representative, and the right to refuse work they believe is likely to endanger themselves or another worker. Supervisors have an active legal duty to support all three - not just to avoid obstructing them. Workplaces with 20 or more workers must have a JHSC with a minimum of four members; workplaces with 6 to 19 workers must have a designated health and safety representative. The employer must respond in writing to JHSC recommendations within 21 days.
