"Due diligence is demonstrated by the actions taken before an event occurs, not after."

Supervisor Due Diligence training outlines the the legal and ethical responsibility supervisors and employers have to take all reasonable precautions to prevent workplace accidents and injuries.

What is Due Diligence?

Under Ontario’s Occupational Health and Safety Act (OHSA), due diligence means that supervisors must demonstrate they have made every effort to identify and address hazards, provide necessary training, and maintain a safe work environment.

Due diligence is more than meeting legal requirements—it’s about holding individuals accountable for both their actions and their failures to act.

Training Supervisors on Due Diligence will foster a Proactive Safety Culture that Protects Workers and Minimizes Risk

By training Supervisors how to integrate due diligence principles into daily operations— like conducting regular inspections, providing effective training, and keeping detailed records—you can foster a proactive safety culture that protects workers and minimizes risks.

Supervisors will be able to demonstrate strong leadership and accountability through their actions, which sets the tone for the entire organization. Consistent efforts to address hazards, enforce compliance, and improve safety protocols help build trust, reduce incidents, and uphold legal standards.
