    Protecting Your Renovation Project: A Guide to Builder's Risk Insurance in Ontario

    The Insurance LabJune 15, 2026

    Your home is likely your biggest asset, and embarking on a major renovation project is an exciting, yet significant, undertaking. Whether you are adding an extension, remodelling your kitchen, or completing a full structural overhaul, there are many risks involved. From accidental damage to unforeseen circumstances, a lot can go wrong during construction. This is where builder's risk insurance, also known as course of construction insurance, becomes an essential safeguard for your investment.

    What is Builder's Risk Insurance?

    Builder's risk insurance is a specialized type of property insurance designed to protect buildings and materials during the course of construction or renovation. It provides coverage for damages to the structure itself, building materials, fixtures, and equipment that are on site, awaiting installation, or in transit to the construction site. This policy is distinct from typical home insurance, which may not adequately cover the unique risks associated with a construction project.

    Why is it Important for Renovations?

    Standard home insurance policies are generally designed to cover finished structures, not properties undergoing significant changes. During a renovation, your property is exposed to increased risks. Building materials are often stored openly, structures may be partially exposed to the elements, and there is a higher volume of activity with various tradespeople working on site. These factors elevate the likelihood of incidents such as:

    • Fire: Construction sites often involve welding, electrical work, and flammable materials, increasing the risk of fire.
    • Theft and Vandalism: Building materials and tools can be valuable targets for theft, and unoccupied or partially completed structures are more vulnerable to vandalism.
    • Storm Damage: Partially constructed or exposed areas are highly susceptible to damage from wind, rain, snow, or ice.
    • Accidental Damage: Mistakes can happen on any construction site, leading to damage to new or existing structures.
    • Collapse: Structural failures, while rare, can occur during various stages of a renovation.

    Without builder's risk insurance, a significant loss from any of these perils could lead to substantial out-of-pocket expenses, project delays, and even financial ruin for the homeowner.

    Who Needs Builder's Risk Insurance for Renovations?

    While often associated with new builds, builder's risk insurance is critically important for homeowners undertaking major renovation projects in Ontario. This includes, but is not limited to:

    • Major additions or extensions to an existing home.
    • Extensive interior remodels, especially those involving structural changes.
    • Any project where the home will be partially or fully uninhabitable during construction.
    • Projects where the value of the materials and labour is substantial.

    Even if your contractor carries their own commercial general liability or builder's risk policy, it may not extend to cover your property and materials in the same way your own policy would. It is crucial to understand the nuances of their coverage and how it interacts with or differs from your needs as the property owner.

    What Does Builder's Risk Insurance Typically Cover?

    Policies can vary, but generally, builder's risk insurance in Ontario covers:

    • The structure under construction: This includes the existing dwelling and any new additions.
    • Building materials: Materials, fixtures, and equipment to be installed, whether they are on-site, in transit, or being stored at another location.
    • Soft costs: Some policies can be extended to cover additional expenses incurred due to a covered loss, such as interest on construction loans, real estate taxes, and architectural fees.
    • Debris removal: Costs associated with clearing debris after a covered loss.

    The specific perils covered can include fire, lightning, wind, hail, theft, vandalism, and certain types of collapses. Exclusions typically involve poor workmanship, faulty materials, mechanical breakdown, or criminal acts by the insured.

    Key Considerations When Securing Coverage

    When looking for builder's risk insurance for your Ontario renovation, consider the following:

    • Policy Term: Ensure the policy duration aligns with your project timeline, including potential delays. You may be able to extend it if needed.
    • Coverage Limit: The coverage limit should reflect the total completed value of the renovation, including the existing structure and the value of new materials and labour.
    • Deductibles: Understand the deductible amounts you would be responsible for in the event of a claim.
    • Named Perils vs. All Risks: An "all-risks" policy generally provides broader coverage than a "named perils" policy, which only covers risks specifically listed.
    • Existing Homeowner's Policy: Discuss with your broker how your existing homeowner's policy will interact with the builder's risk policy during the renovation period.
    • Contractor's Insurance: Always verify that your contractor carries adequate commercial general liability insurance and any other required coverages, such as WSIB.

    The Role of Your Insurance Broker

    Navigating the complexities of builder's risk insurance requires expertise. An experienced insurance broker can help you assess your project's specific risks, explain the different coverage options, and find a policy that precisely fits your needs. They can also ensure there are no gaps in coverage between your existing home insurance and your new builder's risk policy.

    Embarking on a renovation is a significant investment. Protecting that investment with the right insurance is paramount. Do not leave your project vulnerable to unexpected events and financial setbacks.
