The obligation to notify an insurer of a loss stands as one of the most fundamental duties imposed upon a policyholder, yet it remains surprisingly misunderstood even among experienced professionals. This duty, embedded in both the insurance contract itself and provincial insurance legislation across Canada, creates a framework of reciprocal obligations that shapes the entire claims process from its earliest moments. Understanding what the notice obligation requires, where it originates, and how it functions differently across Canadian jurisdictions provides the essential foundation for managing claims effectively within the critical first seventy-two hours following a loss.
At its core, the notice obligation serves a practical purpose rooted in centuries of insurance practice. When a loss occurs, the insurer needs timely information to investigate the circumstances, assess the validity of the claim, preserve evidence, mitigate further damage, and ultimately determine the extent of its liability under the policy. Delay in providing notice can prejudice any of these interests. Evidence may deteriorate or disappear. Witnesses may become unavailable or their memories may fade. Opportunities to mitigate damage may be lost. The insurer may be deprived of the chance to participate in decisions that affect the ultimate cost of the claim. For these reasons, insurers have historically required prompt notice as a condition of coverage, and legislatures across Canada have codified variations of this requirement into provincial insurance statutes.
