How Long is a WSIB Clearance Certificate Valid for Subcontractors in Ontario?

12 Jun 2026 4 min read No comments Workers’ Compensation (WSIB) Ontario
💡

In Ontario, a WSIB clearance certificate is generally valid for up to 90 days. Principal contractors must consistently verify these certificates; if a subcontractor’s certificate expires, the principal contractor can be held financially liable for the subcontractor’s unpaid WSIB premiums and potential workplace injuries.

The construction and service industries in Ontario rely heavily on the use of subcontractors. Whether you are managing a massive high-rise development in Toronto, a roadwork project in Sudbury, or residential renovations in Barrie, hiring skilled trades is a daily reality. However, bringing external workers onto your site comes with immense financial risk if you do not monitor their Workplace Safety and Insurance Board (WSIB) status. 👷

A WSIB clearance certificate (often called an eClearance) proves that a subcontractor is registered with the WSIB, has reported their payroll, and has fully paid their premiums. It acts as a legal shield for the principal contractor. Without it, Ontario law allows the WSIB to legally transfer the subcontractor’s unpaid debt directly to you. Understanding the strict validity periods of these certificates is the only way to protect your company’s bottom line.

Step-by-Step Process for Managing eClearances in Ontario

Managing clearance certificates is not a one-time task; it is an ongoing administrative duty. A certificate that was valid when the subcontractor started a project in Oshawa might expire halfway through the job. Here is how principal contractors must manage this process.

Step 1: Understand the 90-Day Renewal Cycle

WSIB clearance certificates do not last for a year. They are issued on a strict 90-day cycle. The WSIB automatically updates these certificates four times a year, usually in mid-February, May, August, and November. Your first step is educating your payroll and site management teams about these specific quarter-end dates.

Step 2: Create a WSIB eClearance Account

As a principal contractor, you must register for a free eClearance account on the official WSIB Ontario website. This portal allows you to search for any business in Ontario and verify their exact standing in real-time. Do not rely on paper copies handed to you by the subcontractor, as these can be easily forged or outdated. 💻

Step 3: Verify Status Before the Job Begins

Before a subcontractor sets foot on your site or signs a contract, you must generate a clearance certificate in their name through the portal. Keep a digital PDF copy of this valid certificate in your project files. This document proves you performed your due diligence before work commenced.

Step 4: Monitor Expiration Dates Constantly

Because construction projects often last longer than 90 days, you must track when the subcontractor’s certificate is set to expire. The eClearance portal allows you to build a custom list of your contractors and will automatically notify you if one of their certificates is revoked or expires due to non-payment of premiums. 📡

Step 5: Withhold Payments if Certificates Expire

This is the most critical step. If a subcontractor’s certificate expires during the job, Ontario law grants you the right to withhold payments to them. You must refuse to pay their invoices until they contact the WSIB, pay their arrears, and generate a new, valid clearance certificate. If you pay an uncleared subcontractor, you become liable.

Step 6: Consult Legal Counsel for Liability Issues

If you are audited and the WSIB assesses you for a subcontractor’s massive unpaid premiums, do not simply pay the bill. Contact an Ontario law firm specializing in workplace insurance. A lawyer can often negotiate with the WSIB, appeal the assessment, or pursue the subcontractor directly in civil court to recover the funds. 💼

How Much Does it Cost in Ontario? 💲

The administrative process of checking certificates is free, but the cost of failing to do so can be catastrophic for a business:

  • Generating Certificates: $0 CAD. The WSIB eClearance portal is completely free to use for all Ontario businesses.
  • Financial Liability: If you hire an uncleared subcontractor, you could be billed for their unpaid WSIB premiums, which could range from a few hundred dollars to tens of thousands of dollars CAD, depending on their payroll size.
  • Injury Costs: Worse, if an uncleared subcontractor is injured on your site, the WSIB may classify them as your direct worker, causing your own company’s premium rates to skyrocket for years.
WSIB eClearance QuarterStandard Expiry Date in Ontario
Quarter 1Valid until May 20th
Quarter 2Valid until August 20th
Quarter 3Valid until November 20th
Quarter 4Valid until February 20th (Next Year)

How Long Does the Process Take?

Generating a clearance certificate online is instantaneous. It takes less than 2 minutes to log into the WSIB portal, type in the subcontractor’s business name or WSIB account number, and download the PDF. However, if a subcontractor is in arrears, it can take them several days or weeks to negotiate a payment plan with the WSIB to get their certificate reinstated.

Frequently Asked Questions (FAQ)

Do independent operators need a clearance certificate?

In Ontario construction, mandatory coverage applies. Even independent operators (one-person companies with no employees) must register with the WSIB and obtain a valid clearance certificate before working on a site.

What if the subcontractor is from another province?

Out-of-province contractors working in Ontario must still register with the Ontario WSIB and obtain an Ontario clearance certificate, unless they meet strict temporary exemption criteria.

Can I just deduct their WSIB premiums from my payment to them?

No. You cannot arbitrarily deduct WSIB premiums from a subcontractor’s invoice and pay the WSIB on their behalf without strict legal authorization. You must withhold the entire payment until they clear their own account.

Is a paper certificate handed to me by the contractor acceptable?

Never rely on a paper copy provided by the subcontractor. Always verify their status directly through the official WSIB eClearance portal to ensure the certificate has not been revoked.
