Yes. Supervisors in Canadian workplaces must receive WHMIS training if they oversee employees who work with or around hazardous products. This training ensures supervisors can promote, enforce, and support WHMIS compliance, as required by law.

Even if supervisors aren’t directly handling the materials themselves, they are responsible for:

• Overseeing safe handling, labeling, and storage.
• Ensuring employees complete both general and site-specific WHMIS training.
• Responding to incidents, spills, and emergencies.
