One-person crews and WSIB coverage.

Which one-person crews, sole proprietors and partners need WSIB coverage in Ontario construction, the narrow exemptions, and what a general contractor should ask for.

The rule since 2013

Since 2013, most people who work in construction in Ontario must have WSIB coverage, including independent operators, sole proprietors and partners. A one-person crew is not exempt just because it has no employees.

Who is covered

The narrow exemptions

What this means for a general contractor

When a small sub tells you it does not need WSIB because it has no employees, that answer is usually wrong in construction. Ask for its own clearance certificate the same as any other sub. In Ontario, a contractor who hires a subcontractor without a valid WSIB clearance certificate can be held responsible for the premiums that sub owes WSIB (Workplace Safety and Insurance Act, section 141).

What to ask for

Keeping it current without chasing

SubProof gives each subcontractor a private upload link, no account needed. It reads the expiry dates you enter, shows every sub as covered, expiring or expired, and emails the sub 30, 14 and 7 days before a document runs out and on the day. You get a Monday summary of who needs attention before you approve the week's payments.
