7 mistakes property managers make when they rely on WSIB compliance claims

Each numbered item names a common vetting error, explains why it matters, lists the exact documents to request, and gives a one-line phone or email script you can copy. Official WSIB and Ontario guidance are cited so you can verify practices directly.

1) Accepting verbal WSIB claims without a clearance certificate

The mistake: awarding work because a contractor says they are WSIB covered without asking for a clearance letter or account number. Why it matters: clearances show a contractor was registered and in good standing when issued and are used by hirers to avoid premium liability. See the WSIB business guide for how clearances are used in procurement.

What to request: a WSIB clearance letter or clearance confirmation that shows the contractor’s WSIB account number, issue date, expiry date, and a statement that the business is in good standing. If you doubt the claim, ask for a recent statement of account.

One-line verification script: “Please email your WSIB clearance letter and account number so I can confirm coverage before awarding the job.”

Reference: WSIB: Your guide, services and responsibilities.

2) Confusing independent operator exceptions with full coverage

The mistake: assuming every worker on site is covered because the company is registered. Some workers can be classified as independent operators or fall under specific exemptions, which affects who is covered for injuries and premiums.

What to request: a list of all independent operators or subcontractors who will work on site and each person or firm’s WSIB classification or exemption documentation. If anyone is claimed as an independent operator, ask for written proof and verify the rule with WSIB guidance.

One-line verification script: “Please list any independent operators who will work on site and attach their WSIB classification or exemption documentation so we can confirm coverage.”

Reference: WSIB: Independent operators in construction.

3) Overlooking expiry dates and scope limits on clearance letters

The mistake: accepting a clearance that is expired or that explicitly excludes the type of work you need. Clearances can be time limited or restricted to defined activities, which makes them invalid for a different scope or for work that runs past the expiry date.

What to request: confirm the clearance issue and expiry dates and ask whether the clearance explicitly covers renovations, multi‑unit turnovers, and the specific trades involved. If the project will continue past the expiry date, require a renewed clearance before work continues.

One-line verification script: “Does your clearance cover renovations and multi‑unit turnovers, and what is the expiry date? Please email the clearance so I can verify.”

4) Not matching WSIB coverage to the project scope and trades

The mistake: assuming a contractor’s WSIB registration automatically covers all trades and activities in your scope. Different activities can carry different classifications and premium categories.

What to request: a scope‑matched statement from the contractor confirming their WSIB registration and insurance cover the specific trades and tasks you need, for example full unit turnover, kitchen remodelling, concrete, tiling, or plumbing.

One-line verification script: “Confirm that your WSIB coverage and insurance include [concrete, tiling, plumbing] work for occupied multi‑unit projects and email the supporting documents.”

5) Failing to verify account standing and outstanding premium risk

The mistake: trusting a clearance at face value without confirming the contractor is in good standing and has no outstanding premium liabilities. If premiums are owed, a hiring party may face downstream risk in some circumstances.

What to request: a clearance that explicitly states the contractor is in good standing and, when appropriate, a recent WSIB statement of account or confirmation from the WSIB that the account has no outstanding assessments.

One-line verification script: “Can you provide a WSIB clearance showing you are in good standing and a recent statement of account for our records?”

Reference: WSIB business guide, which explains why businesses rely on clearances to avoid premium liability.

6) Skipping a certificate of insurance and the additional insured endorsement

The mistake: relying solely on WSIB clearance and ignoring commercial liability insurance and endorsements. A valid certificate of insurance (COI) should name the owner or hirer as additional insured for the project, list coverage limits, and reference the project dates and address.

What to request: a current COI showing commercial general liability limits, policy number and insurer, and an endorsement or wording that names you as additional insured for the specific project and dates.

One-line verification script: “Please send a certificate of insurance naming [owner/manager] as additional insured for this scope and include policy dates and limits.”

7) Ignoring tenant safety and occupied-site safety plans even for WSIB-compliant bidders

The mistake: assuming WSIB compliance resolves resident safety and disruption risk. WSIB registration covers workplace insurance and premium standing, but it does not replace a site‑specific tenant disruption plan or occupied‑site safety procedures.

What to request: a written tenant disruption plan, site safety procedures that address occupied‑unit work, the name of a designated site supervisor, and evidence of crew training or orientation relevant to occupied buildings.

One-line verification script: “Share your tenant disruption plan and site safety procedures you will use for occupied units so we can confirm they meet our resident‑safety requirements.”

How to verify a WSIB clearance: step-by-step actions

1. Ask the bidder for the WSIB clearance letter, the WSIB account number, and the clearance expiry date. Request a recent statement of account when appropriate.
2. Request a certificate of insurance with an additional insured endorsement that names the hirer for the project dates and location.
3. Use the WSIB guidance pages and, if necessary, contact WSIB by phone to confirm the clearance and in‑good‑standing status. The WSIB clearance FAQs explain common verification steps.
4. Record the clearance number, issue date, expiry date, COI details, and any confirmation from WSIB in your procurement file. Make renewal or re‑verification a contractual condition if the project spans the clearance expiry.

Decision criteria and real objections: when to decline a bid

Set these procurement rules in tender conditions and enforce them consistently when hiring for occupied buildings.

• Automatic disqualifier: no WSIB clearance letter or no COI naming the hirer as additional insured for occupied‑unit work.
• Automatic disqualifier: clearance that expires mid‑project with no contractual commitment to renew.
• Treat a low bid without full documentation as higher risk than a compliant higher bid; include compliance as a scored criterion.
• If a contractor claims independent operator exemptions for core trades, escalate to WSIB for confirmation before awarding work.
• Red flags: refusal to provide copies, inconsistent scope descriptions across documents, or a COI from an insurer you cannot verify. Ask for clarification or decline the bid.

Ontario-specific considerations for multi-unit and occupied properties

In Ontario the WSIB is the authority for workplace insurance and clearances. When hiring contractors for renovations or repairs, confirm coverage and understand exceptions for independent operators. The Ontario government advises homeowners and property managers to confirm workplace safety and insurance before hiring a contractor. Consult the Ontario consumer guidance and the WSIB pages on independent operators for specifics about exemptions and hirer liability.

Frequently asked questions

How do I check a contractor’s WSIB clearance and confirm they are in good standing?

Request the WSIB clearance letter with the contractor’s account number and expiry date, then confirm details using the WSIB business guidance on clearances and the WSIB clearance FAQs. If necessary, ask the contractor for a recent statement of account to check for outstanding premiums.

What exactly is a WSIB clearance certificate and how long is it valid?

A clearance indicates the contractor was registered with WSIB and in good standing at the time the clearance was issued. Expiry varies, so always check the clearance issue and expiry dates and whether the clearance covers the specific type of work you need. See the WSIB business guide for details.

Are there exceptions for independent operators in construction and how do they affect my liability?

Yes. Some independent operators are treated differently for WSIB coverage. If a subcontractor claims independent operator status, request written proof and check the WSIB guidance on independent operators in construction. Escalate unclear claims to WSIB before awarding work to avoid unexpected liability.

What documents should I require before approving work in occupied multi-unit buildings?

Require a WSIB clearance letter, a certificate of insurance naming you as additional insured, a written scope and timeline, a tenant disruption plan, and a list of subtrades with their WSIB status. These documents protect tenants and reduce procurement risk.
