Workers compensation represents one of the most significant social contracts in Canadian employment law, establishing a framework that fundamentally altered the relationship between employers and workers when injuries occur on the job. The system emerged from a recognition that the traditional tort-based approach to workplace injuries created untenable outcomes for both parties. Workers faced years of litigation with uncertain results, employers confronted unpredictable liability, and the courts became overwhelmed with competing claims about fault and negligence. The solution, developed in the early twentieth century and refined over more than a hundred years, created a no-fault insurance system that provides guaranteed benefits to injured workers while shielding employers from civil lawsuits related to workplace injuries.
The historical foundation of workers compensation in Canada traces to the Meredith Report of 1913, authored by Sir William Meredith, then Chief Justice of Ontario. This landmark document established principles that continue to govern workers compensation across all Canadian jurisdictions today. Meredith articulated what became known as the historic compromise: workers would surrender their right to sue employers for workplace injuries in exchange for guaranteed compensation regardless of fault, while employers would contribute to a collective insurance fund and receive protection from potentially ruinous litigation. This trade-off created mutual benefits that have sustained the system for over a century, though the specific implementation varies considerably across provincial and territorial boundaries.
