The Supervisor Due Diligence course provides managers and supervisors with a clear understanding of their legal responsibilities under provincial occupational health and safety (OHS) legislation. This training explains the roles and duties of workers, supervisors, and employers, and outlines the leadership practices needed to maintain a safe and compliant workplace. Learners will review their obligations under local OHS laws, explore proactive safety measures, and understand how due diligence protects both workers and organizations.

The course emphasizes the importance of recognizing and applying the Internal Responsibility System (IRS), ensuring that everyone in the workplace plays a role in preventing incidents. It also covers the limits of federal legislation, noting that the Canadian Labour Code is not included because all workplaces must comply with their respective provincial laws—which are typically more comprehensive. Participants learn how to identify hazards, apply the hierarchy of controls, support safety committees, and respond appropriately when workers exercise their right to refuse unsafe work.

By the end of this program, supervisors will understand how to meet their legal obligations, support a strong safety culture, and take reasonable steps to prevent workplace injuries and incidents.

Supervisors are legally responsible for protecting the health and safety of the workers they oversee. Understanding provincial legislation, due diligence requirements, and the IRS framework helps ensure that supervisors make informed decisions and recognize their role in preventing incidents. This course provides the foundation needed to interpret legal requirements, manage risks, and maintain compliance.
