A denial letter does not end your claim. In Canada, commercial policyholders have several paths to challenge an insurer's decision, but the window to act effectively is narrower than most business owners expect. The first step is understanding exactly what the insurer is refusing and why, because the response differs depending on whether coverage itself is being denied or whether the insurer acknowledges coverage but disputes how much it owes.
When you receive a denial or a valuation that falls short of your expectations, your immediate priority is documentation. Gather every piece of paper connected to the loss: your policy, all endorsements, your original claim submission, the adjuster's reports, and every written communication with the insurer. Note dates carefully. Many commercial policies impose limitation periods that begin running from the date of loss or the date of denial, not from when you decide to dispute the outcome. In Alberta, the Insurance Act sets a general 2-year limitation for commencing action on a policy, and similar periods apply in other provinces. Missing that window forecloses your options entirely, regardless of the merits of your claim.
The denial letter itself deserves close reading. Insurers sometimes conflate coverage denials with valuation disputes, and the distinction matters. A coverage denial means the insurer says the loss is not covered at all — perhaps because it falls under an exclusion or because a policy condition was breached. A valuation dispute means the insurer accepts that the loss is covered but disagrees about quantum. The remedies available differ. Valuation disputes often trigger appraisal clauses written into commercial property policies, which establish an umpire-driven process to resolve the dollar figure without litigation. Coverage disputes, by contrast, generally require negotiation, internal appeal, or court action.
Your second step is to request a clear, written explanation of the insurer's position if the denial letter is vague. Insurers in Canada owe a duty of good faith, and courts have found that unreasonable delay, inadequate investigation, or failure to explain a denial can itself be actionable. A written request also creates a paper trail that may prove useful later.
From there, consider your escalation paths. Most insurers have internal complaint or appeal processes, and regulators in every province maintain consumer complaint mechanisms. In Alberta, the Superintendent of Insurance receives complaints; in Ontario, the Financial Services Regulatory Authority plays a similar role. These bodies do not adjudicate private disputes, but a regulatory complaint can prompt an insurer to revisit a file. Industry ombudservices, such as the OmbudService for Life and Health Insurance or the General Insurance OmbudService, offer mediation for eligible disputes. None of these paths suspends your limitation period, so pursuing them does not buy unlimited time.
If internal channels fail, litigation remains available, though it is rarely the first choice for a business owner who needs to resume operations. Many commercial policies contain appraisal or arbitration clauses that offer a faster, less expensive route to resolution when the dispute is purely about valuation. Understanding whether your policy contains such a clause, and whether the dispute falls within its scope, is essential before committing to a strategy.
Throughout this process, keep copies of everything and confirm important conversations in writing. Insurers handle thousands of claims; a well-documented file distinguishes yours from the rest and reduces the risk of misunderstanding.
