Which of the following would be considered a "material change in risk"?

This question addresses Statutory Condition 4 (Material Change) under the Insurance Act of Ontario. A material change is defined as a change within the knowledge and control of the insured that is substantial enough to affect the insurer's decision to maintain the policy or the rate of premium charged.

Under the RIBO Level 1 Blueprint, a broker must distinguish between routine maintenance (Options A, C, and D) and changes that significantly alter the physical hazard of the property. The installation of a woodstove (Option B) is a classic example of a material change. Woodstoves introduce a high risk of fire due to potential improper installation, creosote buildup, or improper ash disposal. If an insurer had known a woodstove was present, they might have required a WETT inspection, increased the premium, or declined the risk altogether.

The broker's role in Consulting and Advising is to remind clients that they have a legal duty to report such changes "promptly." Failure to report a material change can give the insurer grounds to void the policy or deny a claim related to that change. This is a critical point in Legal and Regulatory Compliance. While painting or replacing carpets are "cosmetic" and do not affect the risk profile, the broker must act as an educator to ensure the client understands what constitutes a "substantial" change. This technical precision protects the broker from Errors and Omissions (E&O) and ensures the client's coverage remains valid and enforceable throughout the policy term.
