Completed operations insurance is the part of your liability coverage that matters after the job is finished. Many contractor claims do not happen on day one. They show up weeks, months, or years later, when water finds a gap, a component fails, or a client discovers damage and points back to your work.
If you do construction, renovation, repairs, installation, or service work in Ontario, completed operations coverage is often what keeps a normal complaint from becoming a business changing loss.

Contractor insurance in Ontario
Who this applies to
This applies to Ontario contractors whose work can affect people, property, or building systems after handover, including:
Roofing, waterproofing, and exterior envelope
Electrical, controls, and automation
Plumbing, HVAC, and mechanical
Concrete, framing, drywall, and finish carpentry
Restoration, flooring, and tile
General contractors managing multiple trades
Service contractors doing maintenance and repairs
If your projects include condos, retail plazas, warehouses, health care, or multi tenant buildings, completed operations exposure is usually higher because one defect can affect multiple units and multiple parties.
What completed operations insurance is
Completed operations coverage is typically included within a commercial general liability policy, but the limit structure and wording matter. Many contracts, tenders, and owner insurance requirements call out a specific completed operations aggregate limit.
Completed operations coverage: Liability coverage for bodily injury or property damage that happens after your work is completed, caused by your completed work.
Completed operations aggregate: The maximum the insurer will pay for completed operations claims during the policy period, regardless of how many claims occur.
Occurrence limit: The maximum the insurer will pay for one covered loss event. Many policies have both an occurrence limit and separate aggregates.
Defence costs: Legal costs to investigate and defend you in a lawsuit. Defence treatment varies by wording and insurer, so it is worth confirming upfront.
Your work exclusion: A common liability concept where the policy may not pay to redo your own faulty work, but may respond to damage your work causes to other property.
What is covered and not covered
Completed operations coverage is designed for third party injury or property damage caused by your completed work. It is not a warranty program for workmanship.
Common examples of what it can cover
Water damage to finished interiors after an installation issue
Fire or smoke damage traced back to electrical work completed months earlier
A customer injury caused by a loose handrail installed during a prior project
Damage to a client’s equipment caused by a system failure tied to your work
Legal defence and settlement costs when you are sued over completed work
Common examples of what it usually does not cover
The cost to replace or redo your own defective work when there is no resulting damage to other property
Pure contract penalties, liquidated damages, or delay costs unless another coverage applies
Known defects you were aware of and did not correct
Work performed outside the described operations on the policy
Claims that should sit under professional liability when the allegation is design, specification, or advice rather than physical work
If you provide design assist, commissioning, or system specification, completed operations coverage may not be enough on its own. That is where contractor errors and omissions coverage can matter.

Common claim scenarios for Ontario contractors
These are the patterns that tend to produce severe completed operations claims:
Moisture intrusion after roofing, cladding, or window work
Plumbing leaks that damage multiple suites or tenants
HVAC failures that cause frozen pipes, mould allegations, or tenant displacement
Electrical faults that lead to fire, equipment damage, or smoke loss
Improper anchoring or support work that causes collapse or injury
Renovation work that triggers unexpected damage to surrounding property
Many of these claims escalate because multiple parties get pulled in: the owner, GC, trades, property manager, insurer, and sometimes condo boards. The paperwork trail matters as much as the incident itself.
Cost drivers and underwriting questions brokers actually ask
When a contractor asks, “How much does completed operations insurance cost,” underwriters usually care less about the label and more about the story behind the risk.
Expect questions like:
What trades do you perform, and what is excluded
What percentage is new construction vs renovation vs service
Typical project values and your largest job in the last 12 months
Whether you work on condos, high rises, or occupied buildings
Your subcontractor use and how you control certificates and scope
Your written QA process, photos, checklists, and sign offs
Prior completed operations claims and how they were resolved
Whether you do any design assist, specification, or engineering
If your work includes high severity building systems, or if you take on GC responsibilities, the completed operations aggregate limit often becomes a negotiation point with owners and carriers.
How to reduce premium without reducing protection
Lower premiums follow lower claim frequency and lower claim severity. For completed operations, the fastest way to reduce severity is to reduce disputes and improve defensibility.
Practical controls that insurers respect:
Use a standard closeout package on every job
Include photos of key stages, especially hidden conditions
Document test results, commissioning, and acceptance sign off
Track materials and product lots for traceability
Use written change orders, even for small scope changes
Run a subcontractor compliance process that is auditable
Respond early to deficiency notices and document actions taken
Avoid scope creep into design without the right coverage
Short checklist: completed operations risk controls contractors can adopt this month
Standard job file with photos before, during, after
Signed scope and change order log
Commissioning and testing records where applicable
Subcontractor certificates collected before start
Final walk through sign off and closeout notes
Deficiency response timeline with dates and evidence
Mistakes that cause coverage gaps
These are the gaps we see most often in Ontario contractor programs:
The completed operations aggregate is too low for the size of work being pursued
The policy operations description does not match the real work being performed
Subcontractors are treated as a paperwork issue, not a risk issue
Work is expanded into design assist without adding professional coverage
Certificates are issued that promise wording your policy does not actually provide
Work is performed outside Ontario or across Canada without confirming territory and travel exposure
FAQ
Is completed operations coverage the same as a warranty?
No. It is liability coverage for injury or damage caused by completed work. It is not meant to pay for routine deficiencies or cosmetic corrections.
Do I need completed operations coverage if I only do small jobs?
Often yes. Small jobs can still cause large losses, especially water damage, fire, and tenant displacement.
How long can completed operations claims show up after a job is done?
It depends on the claim and the contract environment. The practical point is that the exposure can outlive the job by a long time, so limits should reflect that.
What is the difference between occurrence limit and completed operations aggregate?
The occurrence limit applies to one incident. The completed operations aggregate is the total available for all completed operations claims during the policy period.
Does completed operations cover the cost to redo my work?
Usually not by itself. It often responds to resulting damage to other property, not the cost to replace your faulty work.
What if the owner requires higher limits than my policy has?
That is common on larger projects. You may need higher limits, an umbrella, or a different structure depending on contract wording and the completed operations aggregate requirement.
Do I need a separate policy for completed operations?
Sometimes it is included in your CGL, but the limit structure may be the problem. The right fix depends on your contracts, trades, and project size.
