WSIB clearance, read properly
A WSIB clearance certificate is one of the most-collected and least-read documents in Ontario construction. It gets glanced at, filed, and treated as a permanent pass. It is none of those things.
What the certificate actually does is narrow and specific: for the period it names, it confirms that the contractor’s WSIB account is in good standing and releases the party who hired them from liability for that contractor’s unpaid WSIB premiums. That is the whole function. It is a financial release tied to a window of time.
Here is what it does not tell you, and what people routinely assume it does:
- It says nothing about liability insurance. WSIB and CGL are separate systems covering separate risks.
- It says nothing about competence, training records, or safety performance.
- It does not stay valid indefinitely — every certificate carries its own validity dates, and the one that mattered in March is not the one that matters in September.
- It does not cover a different legal entity than the one printed on it.
That last point is where most real exposure hides. Operating names, numbered companies and legal names drift apart constantly in this industry. A certificate issued to a numbered corporation is worthless if your contract, your invoices and your site sign-in sheet all name a differently-registered operating business. Match the legal entity on the clearance certificate to the legal entity on the contract, character for character — not close enough, exactly.
The verification routine
Do not accept a forwarded PDF as proof. Pull the clearance yourself through WSIB’s own clearance service using the contractor’s account or firm number. It takes a couple of minutes, it produces a record under your control, and it is the only version that cannot have been edited before it reached you. Re-pull it before releasing payment, not just at onboarding.
Coverage in Ontario construction is broad by design. Since the mandatory-coverage rules came into force, independent operators, sole proprietors and partners working in construction generally have to register with WSIB rather than opting out, with narrow exemptions. The practical effect for a GC is that “he’s a one-man operation, he doesn’t need WSIB” is very rarely the right answer, and it is not an answer you want to be defending after an incident.
Onboarding before mobilization
The cheapest moment to find a compliance problem is before anyone is standing on your site. Once a crew has mobilized, every missing document becomes a scheduling problem, and scheduling problems get resolved in favour of keeping the job moving.
A workable onboarding package is short enough that subs actually complete it and specific enough to be worth collecting:
- Legal entity confirmation. The exact registered name, matched against the contract, the clearance certificate and the insurance certificate.
- Current WSIB clearance, verified at source as above.
- Certificate of insurance with the correct limits, the correct additional insureds, and the project identified.
- Health and safety policy and program, plus the name of the site supervisor who will actually be there.
- Training records for the workers attending — Working at Heights for anyone using fall protection on a construction project, WHMIS, and any equipment-specific certification the scope requires, such as elevating work platforms.
- Signed scope acknowledgement. Not the quote — a scope document that states inclusions, exclusions and the assumptions the price rests on.
- References that get called. Two recent, comparable projects, contacted before award rather than after a problem.
The discipline that makes this work is refusing to let an incomplete package through on the promise that the missing item is coming. It is always coming. Set the rule that mobilization follows a complete file, and the file arrives complete.
Insurance a GTA sub should carry
Commercial General Liability is the baseline, and $2,000,000 per occurrence is the common floor for residential and light-commercial work in the GTA. Larger commercial, institutional and high-rise scopes frequently require more, and the requirement should be set by the project rather than by habit.
Limits are the part everybody checks. The parts that decide whether a claim actually responds are usually the parts nobody checks:
Worth verifying
- Additional insured status for the owner and the general contractor, by endorsement
- Cross-liability or severability of interests
- Products and completed operations, extending past substantial performance
- Non-owned automobile coverage
- Notice-of-cancellation provisions
Common false comfort
- A certificate alone — it is a snapshot, and it does not amend the policy
- “Additional insured” typed on the certificate with no endorsement behind it
- A policy that expired between award and mobilization
- Limits that satisfy the contract but not the actual exposure of the scope
A certificate of insurance is evidence that a policy existed on the day it was issued. It is not the policy, it does not change the policy, and it does not create additional-insured status on its own — that comes from an endorsement. For any scope where the exposure is meaningful, ask for the endorsement, not just the certificate.
Scope also drives what else belongs on the list. Exterior envelope work, hot work, and anything disturbing existing building materials each carry their own considerations, and the right coverage question is set by what the crew will physically be doing.
Ontario Construction Act basics
Ontario’s Construction Act — the statute formerly known as the Construction Lien Act — sets the rules for how money moves on a construction project. Trade partners do not need to be lawyers about it, but working without knowing its structure means signing up to timelines you cannot see.
The four load-bearing concepts:
01
The proper invoice. Prompt-payment timelines do not start when you send a bill — they start when you send a proper invoice, which is a defined term with required content. An invoice missing required information may not have started any clock at all.
02
Prompt payment. Once a proper invoice is delivered, the Act sets the period in which the owner must pay the contractor, and a further period in which the contractor must pay its subcontractors after being paid. Withholding payment is permitted, but it requires a notice of non-payment delivered in the prescribed form and time — silence is not a valid way to withhold.
03
Holdback. A statutory holdback is retained from each payment and released on the schedule the Act sets. It is not a discretionary retainer, and it is not the same thing as deficiency money.
04
Liens and adjudication. Lien rights are preserved and perfected within fixed statutory periods running from defined trigger events, and they expire hard. Separately, the Act provides interim adjudication — a fast, binding-for-now process for payment disputes that avoids waiting years for a courtroom.
One practical takeaway
Diarize dates from the trigger event, not from when the problem became obvious. Lien and notice periods are calculated from things like last supply of services or materials, publication of substantial performance, or delivery of a proper invoice — and a missed statutory deadline is not curable by being right about the money.
This is general information about how the framework is structured, not legal advice, and it does not account for the terms of any particular contract. On a live payment dispute, current statutory timelines and the wording of your own contract are what matter — get advice from a construction lawyer on the specifics.
How FAIME handles it
FAIME Construction Inc. is an incorporated Ontario contractor, WSIB active under Class G5, carrying $2,000,000 in commercial general liability coverage. Clearance and certificate of insurance are issued on request, and in practice they go out the same day — because a GC chasing paperwork is a GC whose schedule we are already costing.
Regulated trades are the one place we are deliberate about the language: FAIME self-performs its finishing and envelope scopes with its own crews, and any regulated work — electrical, plumbing, gas — is carried out by licensed subcontractors under our coordination. FAIME does not hold those licences and does not claim to. The same verification standard described above is what we apply to our own subcontractors before they mobilize.
Every scope we price goes out as a written document with inclusions and exclusions stated, and workmanship is backed by a two-year warranty. If you are assembling a bid list and need the compliance package up front, ask for it — it is the first thing we send, not the last.
