Contractors & Developers
Contractor insurance is not one policy. It is a stack of them, and on most projects the contract you signed dictates the shape of that stack before an underwriter ever sees it. This page sets out what the standard Canadian forms actually cover, where the wordings bite, what CCDC 2 and CCDC 41 oblige you to carry, and how bonding sits alongside the insurance on a bid.
What Contractor Insurance Actually Covers
A contractor insurance program is assembled from separate policies, each answering a different question: who pays the third party, who pays for the work itself, who pays for the machine, and who pays when the schedule slips. The layers below are the ones almost every construction and development operation needs, and together they are what most people mean by contractor insurance. The sections that follow explain where each of them stops.
- Commercial General Liability — the third-party layer
- Builder’s Risk / Course of Construction — the project itself
- Wrap-Up Liability — one policy across the whole project team
- Contractors Equipment and Tools — owned, leased and rented-in
- Commercial Auto and Non-Owned Auto — the SPF 6 form
- Contractors Professional Liability — design and design-build risk
- Contractor’s Pollution Liability — now a CCDC 41 requirement
- Subcontractor Default Insurance — the alternative to certificate-chasing
- Cyber Liability — the exposure CCDC 2 does not ask for
- Surety Bonds — credit, not insurance
Where the Liability Policy Stops
Canadian contractors do not write on US forms. The standard wording here is IBC 2100, an occurrence-triggered policy drafted around a simple idea — a liability policy is not a warranty on your own work. Four points decide most contractor insurance coverage arguments.
“Your work” is excluded — the damage it causes often is not
The cost of redoing defective work is excluded; resulting damage to other property generally is not. The distinction that matters is your role. A general contractor’s “work” is the entire project, while a sub-trade’s “work” is only its own scope — so the same loss produces very different answers depending on which chair you are sitting in.
Broad Form Property Damage narrows the exclusion, it does not delete it
A BFPD endorsement typically changes the exclusion from work performed “by or on behalf of” you to work performed “by” you, which can restore cover where a subcontractor was the cause. Canadian courts have treated it as a narrowing rather than a removal, so it should be read alongside the completed-operations wording rather than relied on as a cure-all.
Contractual liability and the insured-contract exception
Liability assumed by contract is excluded, subject to an insured-contract exception covering tort liability assumed before the loss, leases, easements and municipal indemnity requirements. It does not extend to indemnifying an architect, engineer or surveyor for errors in design, approval or instruction — a recurring trap in design-build agreements.
Professional services are excluded outright
IBC 2100 carries a professional services exclusion. Any design responsibility you take on — including the design portion of a design-build contract, or a shop-drawing decision that becomes a design decision — belongs to a Contractors Professional Liability policy, not to the general liability policy.
Builder’s Risk: What It Covers, and Exactly When It Lapses
Course of construction insurance sits over the project rather than over anybody’s negligence. Under an unamended CCDC 2 the contractor places it in the joint names of contractor, owner and consultant, with subcontractors included as insureds, and it carries a waiver of subrogation so the covered parties are not litigating against each other mid-build. The lapse triggers are where contractor insurance programs most often fall down.
The three lapse triggers under GC 11.1
Coverage runs to the earliest of ten calendar days after Ready-for-Takeover, occupancy or use of any part of the work, or the site being left unattended or without construction activity for thirty or more consecutive days. In this climate the thirty-day trigger and the partial-occupancy trigger are the two that actually bite — winter shutdowns and phased tenant occupancy both qualify.
Existing structures are not automatic
Most builder’s risk forms cover the new work only. On a renovation the existing building has to be added by endorsement, insurers frequently apply sublimits on older wood-frame stock, and some forms carry restrictions where tenants remain in place. The owner’s own property policy is not the answer — and it may not respond at all if the owner never told their insurer the work was underway.
Soft costs and delay in start-up
Hard costs are materials and labour. Soft costs — consultant fees, financing and interest, legal and accounting, leasing and marketing — require their own endorsement and are never automatic. Delay in Start-Up is the construction equivalent of business interruption, responding to lost net profit, fixed expenses and debt service when insured physical damage pushes the schedule.
Testing and commissioning is its own grant
The period when systems are first energised and run is a distinct coverage grant, and on a mechanical or electrical project it is frequently where the largest single loss occurs. Contract specifications routinely require builder’s risk to extend to testing, commissioning and installation of machinery. Confirm it is written into the contractor insurance schedule rather than assumed.
A limit set at bid is stale by the time you top out
Contract specifications commonly require a limit of not less than 1.1 times contract price. Reporting through Canadian Underwriter, Suncorp Valuations put building-code enhancements at eight to ten per cent of construction cost and tariff effects at eight to twelve per cent of total project cost. On a two-year build, a ten per cent cushion is not a comfortable margin.
Appetite is segmented by construction type
Non-combustible construction attracts ample capacity and competitive pricing where risk management is strong. Wood frame draws elevated scrutiny, tighter terms, higher deductibles and specific risk-control conditions on the back of loss frequency. Mass timber sits between the two, with insurers expanding appetite but pricing still inconsistent between markets.
The Defects Wording Decides Who Pays for the Rework
Every builder’s risk policy excludes something about defective design, materials or workmanship. The only question is how much, and it is the most consequential single wording in a contractor insurance program. The London Engineering Group wordings are the ones most commonly encountered in the Canadian market, and the gap between them is the gap between a covered claim and an argument.
- LEG 1/96 — the outright defects exclusion. No cover for the defect, and no cover for the damage it causes. The broadest exclusion and the narrowest cover of the three.
- LEG 2/96 — the consequences wording. Pays the resulting damage, then deducts what it would have cost to put the defect right the moment before the damage happened.
- LEG 3/06 — the improvement wording. Pays the damage and funds the rectification, deducting only the portion of cost that improves on the original design or specification. The reach of that improvement carve-out is still argued over, so the wording should be read rather than inferred from the label.
What this looks like on a real loss
A defectively made connection lets go and floods three floors. Under LEG 1 you are on your own for all of it. Under LEG 2 the flood damage is paid, less the notional cost of correcting that connection immediately before it failed. Under LEG 3 the rectification comes with it, less any betterment over the original specification.
The DE series, and why you rarely see it here
The international DE 1 to DE 5 clauses run roughly parallel — DE 3 sits near LEG 2 and DE 5 near LEG 3 — but they are framed around reinstating the defective element after the loss rather than around the pre-loss rectification cost. Canadian builder’s risk placements are dominated by the LEG series; DE wordings turn up mainly on large international infrastructure programs.
Wrap-Ups: Who Is Insured, and for How Long
A wrap-up covers the whole project team under one liability policy, sponsored either by the owner or by the general contractor. It removes the finger-pointing between trades on a third-party claim and it typically extends to damage to existing property, which is why it earns its keep on renovation work. It is not, however, a replacement for your own contractor insurance program.
Who is inside the policy, and who is not
Owners, developers, the general contractor, the project manager, subcontractors and consultants are normally insureds — consultants subject to a professional liability exclusion. Suppliers and security firms typically are not. Read the schedule of insureds before assuming your exposure sits inside it rather than inside your own contractor insurance.
The completed-operations gap — the number that matters most
CCDC 41 (2020) requires products and completed operations to be maintained for six years after Ready-for-Takeover, with additional-insured status for the owner and consultant over the same six years. Wrap-up completed-operations extensions in this market commonly run twenty-four months, sometimes twelve or thirty-six by negotiation. The years in between have to come from your own practice contractor insurance policy.
Faulty workmanship is still excluded
A wrap-up excludes the defective work itself and responds to the resulting property damage. Because the duty to defend follows the pleadings, a claim alleging both will usually pull the policy in — and the party that sponsored the wrap-up wears the loss, even where a subcontractor did the deficient work.
Price it into the tender, not after award
Wrap-up cost is real contractor insurance spend and it belongs in the estimate. Getting an accurate figure at the bid stage, rather than discovering it at award, is often the difference between a margin and a surprise on a project that is otherwise priced correctly.
Subcontractor Certificates and Contractual Risk Transfer
Canada has no standardised additional-insured endorsement. CCDC’s own bulletin puts it plainly — Canadian insurers use varied clauses, unlike the standardised US endorsements. What your subcontract asks for and what the sub’s insurer actually issues are two different documents, and only one of them is coverage — a distinction that sits at the centre of day-to-day contractor insurance administration.
- A certificate of insurance evidences coverage. It does not grant, extend or amend it, and a certificate holder receives no coverage and no legal rights.
- Additional insured status is created by endorsement. Ask for the endorsement itself — some insurers issue only a certificate, which leaves the position legally uncertain.
- A certificate cannot tell you the policy was cancelled last week, that the aggregate has been eroded by earlier claims, or which exclusions apply.
- CCDC 2 and CCDC 5B require the contractor to add the owner and consultant as additional insureds, excluding their sole negligence, for six years after Ready-for-Takeover.
- Confirm exact legal entity names and re-verify at every renewal — a sub that changes carrier mid-project takes your additional-insured status with it.
- Waiver of subrogation matters as much as the limit. Subs are often unnamed insureds under builder’s risk, but where the contract expressly allocates negligence risk to them, that protection can fall away.
- CCDC 2 does not require mould, asbestos, terrorism or cyber cover, so those sit as uninsured indemnity exposure unless supplementary conditions deal with them.
- Where certificate-chasing has become unmanageable, subcontractor default insurance is the structural alternative to managing certificates one at a time.
Design Responsibility and Environmental Exposure
Two exposures sit just outside the general liability policy and are now written directly into the standard contract documents. Both are worth confirming as part of the contractor insurance review before signature rather than after a loss.
Contractors Professional Liability
Written for general and specialty contractors, construction managers and design-builders on a claims-made basis. It answers third-party financial loss arising from professional services and, in the Canadian market, bodily injury and property damage arising from them too — precisely the gap the CGL’s professional services exclusion leaves. Mitigation-of-loss cover, which funds reasonable steps to head off a loss once a design error is found but before a claim lands, is among its more valuable features.
Contractor’s Pollution Liability is now a contract requirement
CCDC 41 (2020) requires $5,000,000 per occurrence of contractor’s pollution liability. That is contractual, not merely prudent. Canadian markets write it for gradual as well as sudden and accidental conditions, on either a claims-made or occurrence basis, and it should be confirmed to include clean-up costs and not only third-party injury and damage.
Reporting windows and tails are short
Contract specifications commonly set reporting periods of one hundred and twenty to two hundred and forty hours for a sudden release, and underground infrastructure work often calls for a minimum three-year extended reporting endorsement. Claims-made cover is only ever as good as the tail purchased behind it — which is a decision made at renewal, not at claim.
Bonding Capacity and How It Is Underwritten
Surety is not insurance and it is not risk transfer. It is a three-party credit assessment between you, the owner and the surety, and you sign a general indemnity agreement obliging you to reimburse the surety for anything it pays. It is underwritten to a zero-loss expectation, which is why bonding is assessed quite separately from contractor insurance, and why not every contractor can obtain a facility at all.
Bid bonds — CCDC 220
The Canadian standard form, refreshed in 2024 for the first time since 2002. The 2024 edition defines the validity period after bid closing and removes the tender date, which had caused confusion around addenda and extensions. Bid security is commonly ten per cent of the bid, though owners specify anywhere from roughly two and a half to fifteen per cent.
Performance bonds — CCDC 221
Guarantees completion in accordance with the contract. The 2024 form expands the claims procedure and introduces an optional pre-notice meeting, so a potential default can be worked through before it is declared one. Amounts are commonly set at fifty or one hundred per cent of the contract price depending on the owner and the jurisdiction.
Labour and material payment bonds — CCDC 222
Protects those supplying labour and material to the project. Coverage extends one subcontract level only, so second-tier suppliers sit outside it — a point worth making early to anyone who assumes otherwise. The 2024 edition removed the ninety-day claim limitation that had caught out late claimants under the 2002 form.
The three Cs
Character, capacity and capital. Reputation, integrity and litigation history; the operational and financial ability to handle the size and complexity of the work, including equipment and expertise; and net worth, equity and working capital. Capacity is earned by completing bonded work cleanly, not by asking for a larger number.
What the surety will want to see
Externally prepared year-end statements — a compilation or review engagement at minimum, with audit accepted but rarely mandatory — plus interim statements with aged receivables and payables once you are more than about four months past year-end. Upgrading the accounting standard is the most reliable single way to lift a facility.
Agreement to bond
A letter from the surety confirming it will issue the performance and payment bonds if the contract is awarded. Owners increasingly ask for it at tender, alongside or instead of bid security, and it is a useful early test of whether your facility will actually support the job you are chasing.
Workers’ Compensation, Liens and Prompt Payment
The contractor insurance program is only half the picture. Three statutory items decide whether a contractor gets paid, and whether a subcontractor’s injury lands on the contractor’s own account.
WCB clearance letters are a live financial exposure
Registration is mandatory in a mandatory industry — construction is one — at three or more workers at the same time, within ten days. If a sub in a mandatory industry has no coverage, the hiring contractor must include the labour portion in its own assessable payroll, pay those premiums and carry the claims, and cannot withhold the premiums from the sub. If the sub has coverage but is not in good standing, both are jointly responsible, and that is the only case where withholding is permitted. Check clearance each quarter, not once at award — it is the cheapest contractor insurance housekeeping there is.
The lien clock under the Builders’ Lien Act
Ten per cent holdback, retained for sixty days after the contract is substantially performed. A claim of lien registers within sixty days of completion or abandonment — or within seven days of the final certificate on an architect- or engineer-supervised contract. The action and certificate of lis pendens follow within one hundred and five days, or thirty days in the supervised case. Under CCDC 2 the mutual waiver of claims begins five days before the lien period expires, so the two clocks are linked.
Prompt payment is passed here, but not yet in force
The prompt payment amendments received Royal Assent in 2019 and the adjudication authority was established in 2022, but the regulations remain under development and the regime has not been proclaimed. New Brunswick’s Act, assented to in 2023, sits in the same position. Federal projects are already covered by the federal Act, and Ontario, Alberta, Saskatchewan and Manitoba are live. The amending legislation carries no grandfathering clause, so contracts signed today may be caught on proclamation — a reason to build notice and adjudication mechanics into your contracts now.
Frequently Asked Questions About Contractor Insurance
What does contractor insurance cost?
It is rated off payroll and receipts by class of work, claims history, the limits your contracts demand, and how much you self-perform versus sublet. A framing contractor and a mechanical contractor with identical revenue are not the same contractor insurance risk. At tender stage the more useful contractor insurance question is what the contract obliges you to carry, because that — not the premium — usually drives the number.
Does my liability policy cover work a subcontractor did badly?
The cost of redoing the defective work is excluded; damage that defective work causes to other property is generally covered. Whether the exclusion swallows the whole job turns on your role. A general contractor’s “work” is the entire project, so a sub’s defect can sit inside the GC’s own excluded work in a way it never would for that sub.
Who is supposed to buy the builder’s risk policy?
Under an unamended CCDC 2 the contractor places it, in the joint names of contractor, owner and consultant, with subcontractors included as insureds. Amended supplementary conditions frequently move that obligation to the owner, so the contract, not the default contractor insurance arrangement, governs.
What are the current CCDC 41 limits?
The 2020 edition raised general liability and automobile liability to $10,000,000 each, set manned aircraft and watercraft liability at $10,000,000, introduced $5,000,000 for unmanned aerial vehicles, added $5,000,000 for contractor’s pollution liability, and moved standard deductibles from $5,000 to $10,000.
How long must I carry completed operations after a job finishes?
CCDC 2 requires the general liability policy in effect for one year from Ready-for-Takeover, with products and completed operations maintained for six years from that date, and the owner and consultant held as additional insureds over the same six years.
Is a certificate of insurance enough to prove my sub is covered?
No. It evidences coverage at a moment in time; it does not create it. It will not tell you the policy was cancelled last week or that the aggregate has been eroded. Ask for the additional-insured endorsement itself and re-verify at each renewal.
Does a wrap-up mean I can drop my own liability policy?
No. Wrap-up completed operations commonly run twenty-four months while the contract requires six years. A wrap-up also excludes professional liability and the defective work itself, and it applies only to the project it was written for — your off-site operations and every other job you run sit outside it.
What is the practical difference between LEG 2 and LEG 3?
LEG 2 pays the resulting damage but deducts what it would have cost to correct the defect immediately before the damage occurred. LEG 3 also funds rectification of the damaged defective property, deducting only the portion of cost that improves on the original design or specification.
Do I need a bond and insurance, or does one replace the other?
Both, and they do different jobs. Insurance transfers risk to an insurer that has priced for expected losses. A bond guarantees your performance to the owner, and you indemnify the surety for anything it pays out. A bond protects the owner; it does not protect you.
Is prompt payment legislation in force here yet?
Not yet. The amendments have Royal Assent and the adjudication authority is established, but the regulations remain under development and the Act has not been proclaimed. Because there is no grandfathering provision, contracts in existence at proclamation may be caught by it.
What happens if a subcontractor’s policy lapses mid-project?
Practically, you find out too late, because a certificate carries no notice right. Your own liability policy and any project wrap-up become the backstop, and the indemnity in the subcontract is worth only what that subcontractor can actually pay. This is the exposure subcontractor default insurance was built to replace certificate-chasing with.
Should a contractor carry cyber coverage?
CCDC 2 does not require it, which is exactly why it gets missed. Construction has moved to shared project models and connected site equipment, and reported downtime after an incident in this sector runs to roughly twenty-four days on average — long enough to put a schedule into liquidated damages. It belongs on the contractor insurance schedule alongside everything else, priced rather than assumed.
