Condo Contractor Requirements: Insurance, WSIB, and Building Rules

Every Toronto-area condo corporation puts the same wall between a signed renovation contract and the first day of demolition. Before work starts, the building will demand: a signed alteration agreement, a certificate of insurance showing $2M–$5M in commercial general liability with the corporation named as additional insured, WSIB clearance for the contractor's workers, a refundable damage deposit of $1,000–$5,000, and a scope package with drawings and a schedule. Getting all of it approved typically takes 4–10 weeks.

This is not bureaucracy for its own sake. A condo is hundreds of homes sharing walls, floors, pipes, and one loading dock — the paperwork exists because one careless renovation can damage a dozen other units and the corporation's common elements. The wall filters out contractors who cannot operate at that standard.

Which is the useful insight for owners: the paperwork wall is a free screening tool. A contractor who clears it routinely is showing you something about how they run their business. One who cannot is showing you something too.

A certificate of insurance, or COI, is a one-page document issued by the contractor's insurer summarizing coverage: policy type, limits, and expiry. Boards typically require $2M–$5M in commercial general liability — higher than what many small operators carry — and, critically, they require the condo corporation to be named as an additional insured on the policy for the duration of the project.

The additional-insured endorsement is the part that trips up casual contractors. It means the corporation itself has standing under the policy if renovation work damages the common elements or another unit, instead of chasing the contractor through the courts. A legitimate insurer issues the endorsement in a day or two; a contractor who stalls on it either does not have the coverage or does not want their insurer looking at the job.

Check the expiry date against the construction schedule while you are at it. A certificate that lapses mid-project is a problem the board will catch even if you do not — and a renewal delay mid-renovation can idle the site for weeks.

WSIB clearance is the second document no board will waive. A clearance certificate confirms the contractor's account with Ontario's Workplace Safety and Insurance Board is registered and premiums are current — meaning workers injured on the job are covered by the provincial system.

Why the board cares: without valid coverage, liability for a workplace injury can climb the chain to whoever hired the work — the unit owner and potentially the corporation. A worker hurt in your unit, uncovered, is a financial and legal mess that a one-page certificate would have prevented. That is why property managers verify clearance before releasing keys and fobs, and why clearance status is checkable online in minutes by anyone.

Do the check yourself before signing anything. Ask for the contractor's WSIB clearance number and look it up. We are WSIB covered, and we hand over the clearance certificate with our quote paperwork — a contractor fluent in condo work will treat the request as routine, because it is.

Most corporations hold a refundable damage deposit — typically $1,000–$5,000 — against the common elements for the duration of the renovation. Management inspects the corridor, elevator, and loading areas before work starts and again at the end; damage comes out of the deposit, and the balance is returned.

Protecting that deposit is part of the daily job. Elevator pads on booked service-elevator days, floor protection along the corridor route, door-frame guards, and end-of-day cleanup are the standard kit. So are the operating rules that keep neighbours civil: work confined to weekday hours, usually 9 a.m. to 5 p.m., no wet-cutting of tile or stone inside the unit, and debris moved on booked elevator time at $200–$500 per day rather than dragged through the lobby.

Ask who carries the deposit risk before signing. In our projects, protection and cleanup are our responsibility — if our work damages a corridor, that is our cost, not a surprise deduction from the owner's deposit. Get that allocation in writing; a proper renovation contract spells it out.

There is a whole tier of the renovation market that simply cannot get through a condo's front door, and it is worth understanding why, because the same gaps that stop them at the paperwork wall would have surfaced mid-project anyway.

Cash-quote operators usually carry no commercial general liability at the limits boards demand, and many have no WSIB account at all — the two documents every alteration package requires. Others hold the paper but fail on discipline: condo work means weekday-only hours with no Saturday catch-up, fixed elevator windows, daily protection and cleanup, and cutting done off-site. A contractor priced for freehold pace will either blow the schedule or start cutting corners when the 20–30% condo time premium lands on their fixed price.

The pattern shows up early if you look for it. Vague answers about insurance, reluctance to name the corporation as additional insured, pressure to start before approval — these are the same warning signs covered in our list of red flags when hiring a renovation contractor. In a condo, they are disqualifying rather than merely worrying.

Screening for condo fluency takes one short conversation. Ask four things: Can you send a sample COI naming a corporation as additional insured? What is your WSIB clearance number? Who prepares the board's alteration package — you or me? And which condo buildings have you worked in recently? Confident, specific answers mean the paperwork wall will be a formality. In Toronto, add a fifth check: renovators are required to hold a City of Toronto Building Renovator licence, which is a verifiable credential, not a claim.

A fluent contractor also changes your timeline. Since the 4–10 week approval window is mostly document-driven, a builder with insurance, WSIB, and package templates ready can file a complete application in days and land at the short end of the range — the broader process is laid out in our guide to how to choose a renovation contractor.

We have been doing this since 2004: licensed and insured, WSIB covered, board packages prepared in-house, and a 2-year workmanship warranty on every project. If your building's requirements are sitting in your inbox looking intimidating, send them to us with your scope — clearing that wall is part of our condo renovation service.
