Ontario Builder’s Risk Insurance

When you’re in charge of a construction project in Ontario, everything from weather to theft or accidental damage can threaten your investment. Builders’ risk insurance offers protection for the structure, materials, and progress of work – so your project stays on track.

Protect your construction project with Ontario builder’s risk insurance

Builder’s risk insurance (also known as course of construction insurance) is essential protection for any project in progress. It covers the structure under construction as well as materials and supplies, whether they’re installed, waiting onsite, in transit, or stored offsite. This ensures your investment is protected against risks like fire, theft, vandalism, or weather-related damage throughout the building process.

This type of policy is highly recommended for a wide range of Ontario projects, including:

  • Residential new builds
  • Major renovations or additions
  • Commercial developments
  • Industrial facilities
  • Civil infrastructure projects such as bridges, roads, and public works

We design course of construction (builder’s risk) policies that safeguard your project from day one – covering you from the moment ground is broken until the work is complete. Learn more about what is and isn’t included below.

What does Ontario builder’s risk include?

Builder’s risk insurance provides protection for structures, materials, and expenses during a construction or renovation project. Coverage can vary by insurer, but common inclusions are:

  • Building – The cost to repair or replace the structure under construction after an insured loss.
  • Materials – Replacement value for building materials that are damaged, destroyed, or stolen while on-site, in transit, or temporarily stored off-site.
  • Debris Removal – Costs to remove debris after a covered loss, such as a fire or storm.
  • Soft Costs – Expenses such as architectural or engineering fees, permitting costs, or legal expenses tied to delays caused by a loss.
  • Labour & Equipment – The value of labour and construction equipment lost or damaged during a covered event.
  • Temporary Structures – Coverage for scaffolding, site trailers, or forms used during construction.
  • Testing Coverage – Protection for systems such as HVAC, plumbing, or electrical equipment while being tested.
  • Business Interruption / Project Delay Costs – Compensation for lost income or added expenses if a project is delayed due to a covered loss.

Builder’s risk insurance in Ontario is customizable, so it’s important to work with an Acera Insurance broker to ensure your project is fully protected.

What is not covered with an Ontario builder’s risk policy?

While builder’s risk insurance offers broad protection for construction projects, it does not cover everything. It’s important to understand common exclusions so you can arrange additional coverage where needed:

  • Faulty design, workmanship, or professional negligence – Errors by architects, engineers, or contractors are not included (these are typically covered under professional liability insurance).
  • Intentional criminal acts – Fraud or deliberate damage caused by an owner, employee, or contractor is excluded.
  • Contractor’s tools and equipment – Portable tools and machinery generally require a separate equipment or tools floater.
  • Third-party liability – Injuries or property damage to others are not covered; you’ll need commercial general liability (CGL) insurance for that.
  • Damage to automobiles and auto liability – Company trucks and vehicles must be insured under a commercial auto policy.

Our Acera Insurance brokers can help you identify these gaps and recommend complementary coverages (such as CGL, equipment insurance, or professional liability) to ensure your Ontario construction project is fully protected.

Who needs builder’s risk insurance in Ontario?

If you’re building a new property, completing a major renovation, or overseeing a construction project in Ontario, you likely need builder’s risk insurance. Standard property policies typically don’t cover buildings under construction, leaving you financially vulnerable to losses from fire, theft, vandalism, weather events, or accidents on-site.

Here is a list of groups who commonly require builder’s risk insurance in Ontario:

  • Project managers overseeing complex construction contracts
  • Homeowners undertaking large renovations or building a custom home
  • General contractors managing residential, commercial, or industrial builds
  • Trade contractors such as electricians, plumbers, or framers working on major projects
  • Developers constructing subdivisions, condos, or mixed-use properties
  • Commercial property owners expanding or remodeling office, retail, or industrial spaces
  • Renovation companies handling structural upgrades, additions, or full rebuilds
  • Investors/house flippers financing short-term construction projects

Property loss

You are hired to construct a building for a client. Overnight, a severe weather storm destroys the framing and materials valuing $50,000.

Result: The builder’s risk policy reimburses the cost of repair and replace the damages materials.

Theft

During a construction project $100,000 of materials is stolen from the project site overnight.

Result: The builder’s risk policy reimburses the cost of the materials so that the project can resume without delay.

Product liability

Your contracting company has been hired to do a major building renovation. A fire breaks out during the job and causes damage to the existing structure as well as most of the work already done and materials totaling $300,000 in damages.

Result: Your builder’s risk policy helps to absorb the cost of the additional damages and reimburses the cost to repair the damages as well as the materials lost.

Understanding the cost of builder’s risk insurance in Ontario and how much coverage you need

Course of construction insurance is not one-size-fits-all. The amount of coverage required and the cost of your premium depends on the details of your project. Understanding how insurers calculate coverage values and pricing will help you plan your budget and avoid being underinsured.

The insured value should reflect the total completed project cost, including both hard costs and soft costs:

  • Hard Costs – The direct, tangible expenses of construction, including:
    • Buildings and structural work
    • Labour
    • Materials and fixtures
    • Site preparation and foundation work
  • Soft Costs – The indirect but essential expenses tied to project completion, such as:
    • Permit and inspection fees
    • Architectural, engineering, and design services
    • Loan interest and financing costs
    • Pre-sale and marketing expenses
    • Insurance premiums
    • Inflation adjustments for rising material or labour costs

By accounting for both, you ensure that your project is fully protected in the event of a loss.

How is the price of Ontario course of construction insurance determined?

The premium for builder’s risk insurance in Ontario is based on several project-specific factors, including:

  • Size and scope of the project – Larger and more complex builds typically carry higher risk.
  • Project location – Local crime rates, weather risks (such as flooding or wind), and proximity to fire services all impact cost.
  • Project duration – Premiums are often charged monthly and increase with longer timelines.
  • Quality of materials used – Higher-value or imported materials increase the insured value.
  • Coverage limits and deductibles – Broader protection and lower deductibles raise premiums, while higher deductibles may lower them.
  • Experience of the project team – Well-established contractors with strong safety protocols may qualify for better rates.
  • Insurance claims history – A clean history helps reduce costs, while frequent claims can raise them.

Most builder’s risk policies are billed monthly, for the duration of your project. This ensures that the policy adapts to the length and complexity of your build, rather than being charged as a one-time, upfront fee
