Costly Mistakes and Official Sources
Misrepresentation on a business insurance application: what you must disclose in Canada
What you must disclose on a Canadian business insurance application, how misrepresentation is treated in common-law provinces and in Quebec, with a worked example.
When you apply for business insurance in Canada, you must disclose every fact you know that would materially influence the insurer's decision to accept the risk or set the premium, and you must tell the insurer about material changes during the policy. If you do not, the consequences depend on where you are. In the common-law provinces, a material misrepresentation or non-disclosure can allow the insurer to void the policy and refuse the claim. In Quebec, the Civil Code of Québec reduces the payout in proportion to the premium that should have been charged when the error was honest and the insurer would still have covered the risk, but allows the insurer to annul the policy for fraud or for a risk it would not have accepted.
This guide is part of the costly business insurance mistakes section. It is general information, not legal advice.
What counts as a material fact
A fact is material if a reasonable insurer would have declined the risk, charged a higher premium or imposed different terms had it known. For business liability, the facts that most often turn out to be material are:
| Fact | Why it matters |
|---|---|
| Every activity the business performs | Each activity has its own risk class and wording |
| Revenue and payroll | The exposure base for the premium |
| Claims, lawsuits and incidents | Predict future claims |
| Previous cancellations or refusals by insurers | Signal underwriting concerns |
| Use of subcontractors and whether they are insured | Affects who pays when they cause damage |
| Work in other provinces or the United States | US exposure in particular changes the price |
| Products made, imported or relabelled | Product liability exposure |
| Hazardous activities: heights, hot work, alcohol, children | Major rating and exclusion triggers |
Answering the insurer's questions fully is the minimum. In both systems, you may also need to disclose material facts the insurer did not ask about specifically, though the questions asked are strong evidence of what the insurer considered material.
Common-law provinces
Insurance contracts are contracts of utmost good faith. Provincial Insurance Acts and the common law allow an insurer to rescind or void a policy for material misrepresentation or non-disclosure, typically returning the premium. Points to know:
- The insurer must generally show the fact was material, not merely that it was wrong.
- An innocent mistake can still be material; intent mainly affects whether the insurer can also allege fraud.
- If the policy is voided, there is no coverage for any claim under it, including defence costs.
- Courts read applications in light of how the questions were worded; ambiguous questions are often read against the insurer.
Illustrative pattern. An Alberta catering business states on its application that it does not serve alcohol. In practice, it runs bars at some weddings. A guest who was served at one of those events is later injured in a car crash and sues. The insurer investigates and finds the alcohol service. It may deny the claim and void the policy, leaving the business to fund its own defence.
Quebec: the Civil Code rules
The Civil Code of Québec sets out the disclosure regime directly:
- Article 2408: the client must represent all facts known that are likely to materially influence the insurer in setting the premium, appraising the risk or deciding to cover it.
- Article 2409: the client need not disclose facts the insurer knows or is presumed to know because of their notoriety, unless the insurer asks about them.
- Article 2410: misrepresentation or concealment of relevant facts nullifies the contract at the insurer's request, subject to article 2411.
- Article 2411: in damage insurance, unless the client's bad faith is established or it is established that the insurer would not have covered the risk had it known the facts, the insurer remains liable for the proportion of the indemnity that the premium collected bears to the premium it should have collected.
- Article 2466: during the policy, the insured must promptly notify the insurer of changes that increase the risk.
Worked example of the proportional rule (illustrative)
A Quebec City machine shop reports $700,000 of revenue. Its actual revenue was $930,000, and it also does some welding on clients' premises that it did not mention. The insurer would have charged $3,200 instead of $2,400 had it known. A client's equipment is damaged and the claim is valued at $90,000.
- Ratio: $2,400 / $3,200 = 75%
- Insurer pays: $90,000 x 75% = $67,500
- Uncovered share: $90,000 - $67,500 = $22,500, which the shop must bear
If the insurer could show it would never have insured on-site welding at all, it could seek to annul the policy instead. If it showed bad faith, the reduction would not be available as a defence for the shop.
Material changes during the policy
Disclosure is not just at application time. Tell your insurer, through your broker, before or promptly after:
- starting a new activity or service line
- opening a new location or working in a new province
- hiring employees for the first time or using subcontractors
- a large jump in revenue or payroll
- taking on a contract with unusual indemnity or insurance terms
- receiving a lawsuit or demand, even one you think is baseless
Some changes are handled at audit or renewal, but new activities in particular should be disclosed promptly.
How to protect yourself
- Read the completed application before you sign it, especially if your broker filled it in from a phone call. You are responsible for what it says.
- Keep a copy of the application and any correspondence with the broker about your activities.
- Over-explain unusual activities in a covering note rather than squeezing them into a category.
- Correct errors in writing as soon as you notice them, and ask for written confirmation.
- Ask what a question means if it is unclear, and keep the answer.
If a claim is being denied for misrepresentation, see denied claims and complaints and consider a coverage lawyer, because the outcome often turns on the exact wording of questions and answers. The claims-made gaps guide covers a related issue: reporting known circumstances when changing insurers.
Frequently asked questions
If my broker made the mistake, am I still responsible?
Usually the application is yours, but a broker who failed to record information you gave may be liable to you for the loss. Brokers carry their own errors and omissions insurance for this reason. Keep records of what you told the broker.
Does the insurer have to return my premium if it voids the policy?
Generally yes, unless fraud is involved. In practice the returned premium is small compared with an uninsured claim.
Is rounding revenue down by a few thousand dollars misrepresentation?
A small, honest estimate difference is normally handled at audit. Systematic or large under-reporting is a different matter and can be material.
Do I need to disclose claims against a business I owned before?
If the insurer asks about the claims history of owners or principals, yes. Answer the question as asked.
