The coverage gaps and disclosure errors that turn a claim into an out-of-pocket loss, how to complain, and where to verify the facts.
Most expensive business insurance problems in Canada start with something small: a revenue figure rounded down, a new service line never mentioned to the broker, a professional liability policy replaced without keeping its retroactive date, or a lease that requires a higher limit than the policy carries. These details surface only when a claim is made, and by then the result can be a reduced payout, a denied claim or a lawsuit that runs past the limit.
The guide to costly business insurance mistakes is the starting point and links to every guide in this group. You will find guides on the duty to disclose (including the proportional rule in Quebec's Civil Code), claims-made gaps and limitation periods, what happens when damages exceed your limit, why a CGL policy usually will not cover a privacy breach, how to escalate a denied claim, and a directory of official regulators and sources by province.
This is general information, not legal advice. If a claim has been denied or you have been served with a statement of claim, speak to your broker promptly and consider a lawyer, or in Quebec a lawyer or notary, who handles insurance coverage disputes.
