Course of Construction insurance, often called COC insurance, is designed for buildings that are actively being built, rebuilt, or significantly renovated.
In Oakville, this type of insurance is commonly used for custom homes, large residential renovations, additions, commercial fit-outs, and redevelopment projects across Bronte, Glen Abbey, Kerr Village, Downtown Oakville, West Oakville, and Trafalgar.
The risk during construction is very different from a normal occupied property. Materials may be stored on site, contractors move in and out daily, parts of the structure may be exposed, and the project itself may not qualify for standard homeowner or commercial property insurance during the work.
At a Glance: Course of Construction Insurance
- Designed for buildings under active construction or renovation
- Often used for custom homes, rebuilds, additions, and commercial projects
- Can apply to both residential and commercial construction
- Helps protect structures, materials, and project value
- Different from wrap-up liability insurance
- Different from standard homeowner insurance
- Commonly required by lenders or contractors
- Often used before occupancy permits are issued
How Course of Construction Insurance Works
COC insurance is temporary coverage designed specifically for projects that are still under construction. Instead of insuring a finished occupied property, it insures the project while work is actively happening.
This may include:
- New custom home construction
- Major home renovations
- Structural additions
- Commercial renovations
- Office or retail build-outs
- Rebuilds after demolition
- Properties waiting for occupancy permits
Coverage typically remains active until construction is completed or the building becomes occupied.
What Course of Construction Insurance Can Cover
Coverage depends on the insurer and project type, but COC insurance may help protect against:
- Fire damage
- Theft of building materials
- Vandalism
- Hail damage
- Water damage during construction
- Damage to partially completed structures
- Materials stored on site
- Temporary structures or equipment
For example, a custom home rebuild in West Oakville may have framing, roofing materials, windows, and appliances delivered before the property is fully enclosed. COC insurance may help protect those materials while construction is ongoing.
What Course of Construction Insurance Usually Does Not Cover
In Ontario, the terms “Course of Construction insurance” and “Builders Risk insurance” are often used interchangeably.
In many cases, they refer to very similar types of coverage.
However, some insurers or brokers may use the terms differently depending on:
- Residential vs commercial projects
- Project size
- Policy wording
- Who is arranging coverage
- Scope of renovation or rebuilding
Generally:
- Builders Risk is commonly used for residential custom homes and rebuilds
- Course of Construction is often used more broadly for residential and commercial projects
The important factor is understanding what the policy actually covers during construction.

Course of Construction vs Wrap-Up Liability
Course of Construction insurance and wrap-up liability insurance protect different parts of a project.
COC insurance usually focuses on:
- The building itself
- Construction materials
- Physical damage during the project
Wrap-up liability usually focuses on:
- Third-party injury claims
- Property damage involving contractors or trades
- Liability exposure during construction
A large custom home project in Downtown Oakville may use both types of insurance together because they solve different risks.
Construction Insurance Comparison
Different construction insurance policies protect different parts of a project. Understanding the distinction helps reduce coverage gaps during renovations or rebuilds.
Course of Construction
- Building structure
- Materials on site
- Projects under construction
Wrap-Up Liability
- Third-party injury
- Contractor liability
- Site-related claims
Standard Home Insurance
- Occupied homes
- Finished residential use
- Not built for major construction
Coverage depends on policy wording, project scope, insurer approval, and construction activity.
When Oakville Homeowners Usually Need COC Insurance
COC insurance is often used when projects become too large or complex for standard homeowner insurance.
Examples include:
- Full home rebuilds
- Custom homes
- Tear-down redevelopment projects
- Major additions
- Commercial renovations
- Structural renovations before occupancy permits are issued
The larger the project becomes, the more likely insurers will require specialized construction coverage.
Commercial Course of Construction Insurance
COC insurance is not limited to residential projects.
Commercial projects may also require Course of Construction coverage for:
- Retail renovations
- Office construction
- Restaurant build-outs
- Industrial units
- Warehouse improvements
- Multi-unit redevelopment projects
Commercial construction projects often involve larger project values, more contractors, and stricter lender requirements.
What Course of Construction Insurance Can Cost in Oakville
COC insurance pricing depends on the project type, value, duration, and construction exposure.
Approximate Oakville ranges may include:
- Small renovation projects: approximately $1,500 to $5,000+
- Custom home construction: approximately $5,000 to $20,000+
- Larger commercial projects: significantly higher depending on project value
Factors affecting pricing include:
- Total project value
- Construction timeline
- Vacancy exposure
- Demolition involvement
- Neighbouring property exposure
- Project location
- Type of construction
- Claims history
- Security and site controls
A tight-lot custom build in Downtown Oakville may be underwritten differently than a larger property project in Trafalgar or Glen Abbey.
Common Mistakes During Construction Projects
Insurance problems often happen because coverage is reviewed too late.
Common issues include:
- Assuming homeowner insurance automatically covers renovations
- Starting demolition before insurance changes are approved
- Underestimating project value
- Delays extending beyond the policy term
- Contractors lacking proper liability coverage
- Vacancy periods not disclosed
- Materials left unsecured on site
Construction projects change quickly, which is why insurance should usually be reviewed before work starts.

Frequently Asked Questions
No, but many lenders, contractors, and larger projects require it before construction begins. Even when it is not legally required, it is highly recommended for major renovations, rebuilds, and custom home to protect your liability and property.
The policy may be arranged by the homeowner, builder, developer, or general contractor depending on the project structure and contractual agreements. Responsibilities should be clarified before work starts.
Yes, COC insurance can apply to large renovations, additions, rebuilds, and structural remodeling projects, not just brand-new construction.
Policies are issued for a specific construction timeline. If delays occur, coverage may need to be extended before the policy expires. This is common when occupancy permits or inspections take longer than expected.
COC insurance may cover the project itself while multiple contractors work on site, but contractors still typically carry their own liability insurance separately. The structure depends on the policy wording and project setup.
