WSIB Clearance Renewals: A Field Guide for Trades Owners

What WSIB Clearance Actually Proves

A WSIB Clearance Certificate is Ontario's way of confirming, in writing, that a business is in good standing with the Workplace Safety and Insurance Board. It tells a general contractor two things at once: your premiums are paid, and any worker injured on their site is covered.

For sub-trades, that single document is often the gate between bidding on a project and being paid for one already completed. GCs increasingly require fresh clearance on award, on milestone, and on final invoice.

The 90-Day Clock

A WSIB clearance certificate is valid for 90 days from the date it is issued. After that, the same account can produce a new one in seconds, but the old one is no longer accepted.

This creates a predictable operational pattern. Most trades businesses know they need WSIB clearance. Most have it. And most still get caught short, not because they fell out of compliance, but because nobody pulled the new certificate before the GC asked.

The Three Common Failure Modes

Almost every late WSIB clearance falls into one of three buckets.

1. Operational miss. The account is current, but no one regenerated the certificate after the previous one expired. The fix is a reminder, not a payment.
2. Payment lag. Premium payment was late, the account is in arrears, and the clearance system blocks the certificate until balances are settled. Time to resolve: typically 24 to 72 hours after payment.
3. Account change. A sub-contractor that converted from sole proprietor to incorporated, or vice versa, has a new account number. Old clearance documents reference the old account and are flagged as invalid by the GC.

Knowing which bucket you are in changes what you do next. Operational misses are fixable in two minutes. Payment lags need an actual phone call.

A Renewal Workflow That Holds

The owners who never get caught running stale clearance use a simple, calendar-driven workflow.

• Day 0 (issuance). Pull the certificate from WSIB. Save it in your credential system with the issue date as the reference.
• Day 60. Calendar reminder fires. Check WSIB account standing online. If anything looks off, that is the moment to investigate, not on day 89.
• Day 69 to 75. Pull a fresh certificate proactively. Replace the saved copy. Notify any GCs whose active contracts require updated documentation.
• Day 90. Old certificate expires. The replacement is already in place.

The 21-day buffer between day 60 and day 90 is what makes this workflow forgiving. It absorbs the rare payment issue or system delay without putting any contract at risk.

What GCs Actually Want to See

Three details on a clearance certificate matter to a general contractor:

1. Account number. Must match the legal entity on the contract. Mismatches almost always indicate an entity change that was never reported.
2. Issue date. Anything older than 60 days reads as stale. Many GCs have policies requiring documents under 30 days old.
3. Account status. "Good standing" is the only acceptable status. Any other status, including "review," is treated as non-compliant.

Submitting a clearance directly downloaded from WSIB on the day of request, rather than forwarding an older PDF, signals operational discipline. GCs notice.

The Operational Bottom Line

WSIB clearance is not a financial problem for most trades businesses. It is a workflow problem. Pay the premiums on time, and the certificate is always available. The trick is making sure someone actually pulls it before it is needed.

A single 60-day calendar reminder, attached to the credential record, is usually all it takes to convert WSIB clearance from a recurring scramble into a quiet, automatic part of operations.
