How to Dispute a Business Insurance Claim Denial in Canada

Share

A denied insurance claim does not mean the conversation is over. Canadian policyholders have multiple avenues to challenge a denial, and the path you choose depends on the grounds the insurer cited, the dollar amount at stake, and how much time remains before your limitation period expires. Understanding these options before you act helps you select the route most likely to produce a reasonable outcome without unnecessary cost or delay.

The first step after receiving a denial letter is to read it carefully and identify exactly what the insurer is relying on. Insurers must provide written reasons for denying a claim, and these reasons will reference specific policy language — exclusions, conditions, definitions, or coverage limits. Note every policy provision cited and every factual assertion the insurer makes. If the denial rests on a factual error, gathering documentation to correct that error may be straightforward. If the denial relies on policy interpretation, the dispute becomes a question of contract law, and you will need to understand how courts in your province have historically read similar language.

Most insurers have an internal appeals or reconsideration process, and this is often the fastest and least expensive starting point. You can submit a written request asking the insurer to reconsider its decision, supported by any additional documentation or argument that addresses the denial grounds. There is no standard form for this request; a clear letter explaining why you believe the denial is incorrect, with supporting evidence attached, is sufficient. Internal appeals do not pause your limitation period, so keep track of dates even while the insurer reviews your file. Some insurers respond within weeks; others take longer. If the insurer upholds its denial after internal review, or if it fails to respond within a reasonable time, you can escalate.

Canada's insurance industry operates a voluntary ombudsman service through the General Insurance OmbudService, known as GIO. This service is available at no cost to policyholders whose insurers participate, which includes most major property and casualty insurers operating in Canada. The GIO can review your complaint and attempt to facilitate a resolution, though it does not have binding authority over insurers. Filing a complaint with the GIO does not extend your limitation period, and the process can take several months. For many owner-operators, the ombudsman route is worth pursuing because it costs nothing and sometimes prompts insurers to reconsider positions they maintained during internal review. The GIO process works best when the dispute involves straightforward factual questions or clear policy language; complex coverage disputes involving significant legal interpretation may not resolve through this channel.

Many commercial property policies contain an appraisal clause that allows either party to demand an appraisal when the dispute concerns the amount of loss rather than whether coverage exists at all. If your insurer agrees that your claim is covered but disputes the value, invoking the appraisal clause triggers a process in which each side selects an appraiser, the two appraisers select an umpire, and the panel determines the loss amount. The decision is binding on both parties. Appraisal is faster and cheaper than litigation when the only issue is quantum, but it cannot resolve disputes over coverage itself. Before invoking appraisal, confirm that your policy contains such a clause and that the dispute genuinely concerns amount rather than entitlement. Alberta policies commonly include appraisal provisions, as do policies in most other provinces, though the specific procedural requirements vary by policy wording.

When internal appeals, ombudsman complaints, and appraisal are not available or have not produced a resolution, litigation remains an option. In Alberta, the Limitations Act sets a 2-year limitation period for most insurance claims, running from the date the insured knew or ought to have known that the loss occurred and that the insurer denied the claim. British Columbia and Ontario have similar 2-year periods under their respective limitations statutes. Missing this deadline extinguishes your right to sue regardless of the merits of your claim, so tracking time is essential from the moment you receive a denial. Litigation can proceed in provincial court for smaller claims or in the Court of King's Bench in Alberta for larger amounts. The threshold between these courts affects procedural complexity and cost, and many disputes settle before trial once both sides have exchanged documents and assessed their positions.

Engaging a lawyer early can strengthen your position even if you hope to resolve the dispute without litigation. A lawyer can review the denial grounds, identify weaknesses in the insurer's reasoning, and draft a formal response that addresses each point with legal precision. Insurers sometimes reconsider denials when they receive a well-reasoned letter from a lawyer, particularly if the denial rested on an aggressive interpretation of policy language or an incomplete factual record. Legal fees are a cost of pursuing the claim, so weigh them against the amount at stake and the strength of your position. Many coverage lawyers offer initial consultations at a fixed fee, allowing you to obtain an assessment before committing to a full retainer.

Throughout any dispute, keep meticulous records. Save every piece of correspondence with your insurer, broker, and any third parties involved. Note the dates you send and receive documents, and use delivery methods that create a paper trail. If the dispute eventually proceeds to litigation, this documentation becomes evidence. If the dispute resolves through negotiation, having a complete record protects you against later misunderstandings about what was agreed.

Finally, remember that insurance contracts are contracts of utmost good faith, and insurers have a duty to act fairly when investigating and adjusting claims. If you believe your insurer has acted in bad faith — by denying a claim without reasonable grounds, delaying unreasonably, or misrepresenting policy terms — this conduct may itself give rise to additional remedies. Courts in Canada have awarded damages beyond the policy limits where insurers have breached their duty of good faith, though establishing such a breach requires clear evidence of improper conduct. Not every denied claim involves bad faith; many denials reflect genuine disagreements about coverage. But where the insurer's conduct has been unreasonable, raising that issue can change the dynamics of settlement discussions.

Disputing an insurance claim denial takes time and effort, but the process is structured and manageable for owner-operators who understand their options. Start with the denial letter, work through the available channels in order of cost and complexity, and keep limitation periods in mind at every stage. The denial letter is the beginning of the conversation, not the end.

Will binder write the letter for me if I need to fight with my insurance company?

Binder University

Thanks for the question, William. Binder University publishes educational content to help business owners understand how claims and disputes generally work, but we can't draft letters or represent you in a dispute with your insurer. That kind of work requires a lawyer who can review your policy, your denial letter, and the facts of your specific situation. If you decide to escalate your claim, a coverage lawyer can write a formal response that addresses the insurer's grounds directly and sets out why the denial should be reconsidered. Many lawyers offer initial consultations at a fixed fee, so you can get a sense of your options and the cost before committing to a full retainer.
