WorkSafe and WSIB Basics for Job Sites

Workplace injury insurance in Canada is administered provincially -- WSIB in Ontario, WorkSafeBC in British Columbia, WCB in Alberta and other provinces, CNESST in Quebec -- but the underlying purpose is the same everywhere: covered workers who are injured on the job receive compensation without needing to sue their employer, and in exchange, the employer (and in most provinces, the property owner in certain circumstances) gains protection from being personally sued for that workplace injury.

This is why requesting a clearance certificate before work begins is standard practice, even for a relatively small renovation. A valid clearance certificate confirms the contractor's account is in good standing and that their workers are covered for the period the work is happening. Without it, a property owner in some provinces can be held liable for an uninsured worker's injury on their property.

Coverage requirements differ by province for independent operators and small contractors -- some provinces make coverage mandatory for the construction industry regardless of company size, while others allow certain independent operators to opt out. This is exactly why checking the certificate for the specific dates of the project, rather than assuming coverage exists, is the only reliable approach.

Beyond the paperwork, the practical safety expectation on any job site -- residential or commercial -- includes basic protections: fall protection for work at height, proper guarding on power tools, and a documented process for reporting near-misses and incidents, not just injuries that actually occur.
