The Mistakes That Quietly Undo a Life Insurance Policy

A policy rarely fails loudly. It fails on a form that was filled in quickly years earlier, on a designation nobody revisited after a life changed, or on an old contract cancelled a month before the new one was in force. None of those look like mistakes on the day they are made.

What the law asks of the person applying

The duty is not buried. Article 2408 of the Civil Code of Quebec says that the client, and the insured if the insurer requires it, is bound to represent all the facts known to him which are likely to materially influence an insurer in the setting of the premium, the appraisal of the risk or the decision to cover it.

Two words in that sentence do the work. KNOWN, because the duty is about what the person knows, not about what a doctor knows and never said. And MATERIALLY, because the test is not whether a fact is embarrassing or old, it is whether it is likely to influence those three things.

The regulator says the same thing in plainer words on its consumer page about buying insurance: notify the insurer of any facts that may influence the insurer in setting the premium. That is the whole obligation, written once by the legislature and once by the Autorite des marches financiers.

What follows from it is the part most people never read.

What happens if something material was left out

Article 2410 is the consequence. Subject to the article on incontestability, misrepresentation or concealment of relevant facts nullifies the contract at the instance of the insurer, even in respect of losses not connected with the risk so misrepresented or concealed.

Read the last clause again, because it is the one that surprises people. The remedy is not confined to the thing that was left out. The article reaches losses that have nothing to do with it.

Article 2424 is the limit on that power, and it has two paragraphs. The first: in the absence of fraud, a misrepresentation or concealment as to risk does not justify the annulment or reduction of insurance which has been in force for two years.

The second paragraph is the one almost every article on this subject leaves out. That rule does not apply in the case of disability insurance if the disability begins during the first two years of the insurance. So a household reading the first sentence and concluding that everything is settled at two years has read half of the article.

Now the confusion that gets repeated everywhere. A misstatement of age is not governed by the two year rule. It has its own article, 2422, which sets out what happens to the insurance when the age given was wrong. Anybody writing or reading about this has to go to the article that actually governs, because merging the two produces an answer that is wrong in both directions.

The designation that nobody revisited

The second family of mistakes has nothing to do with the application form. It is a designation that was right when it was made and was never looked at again.

Article 2455 explains why this matters more than people expect: sums insured payable to a designated beneficiary do not form part of the succession of the insured. The designation, not the will, decides where that money goes. A will that says something else does not move it.

Article 2449 then provides that the designation of the married or civil union spouse as beneficiary is irrevocable unless the contract stipulates otherwise. A person who assumes a designation can always be changed may find that it cannot.

And article 2459 provides that divorce or nullity of marriage, and the dissolution or nullity of a civil union, causes a designation of the spouse as beneficiary to lapse. A person who assumes the old designation still stands may be wrong about that as well.

Those two rules point in opposite directions, which is exactly why neither one should be assumed.

Replacing one policy with another

The third family of mistakes happens in the gap between two contracts.

The regulator publishes the mechanism plainly: when a policy is taken out to replace one already in force, a prior notice of replacement is produced. The document exists so that the comparison between the old contract and the new one is written down, and written down before anything is cancelled rather than after.

The same consumer page tells a reader to consult the register of firms and individuals authorized to practise before doing business with anyone. The register is free, public, and searchable by name.

Nothing in this section is a recommendation about any particular replacement. A replacement can be entirely appropriate. The point is narrower: there is a document that is meant to exist, and the order in which things happen is part of the protection.

What is not published, and why that matters

A reader looking into this will meet a great many articles listing the most common reasons a life insurance claim is refused, usually with numbers attached.

The independent ombudservice for life and health insurance in Canada publishes case studies of individual complaints. Those case studies are useful reading and they are what it publishes. A general ranking of the most common reasons for refusal is not something it publishes, so no such ranking can honestly be attributed to it.

That is worth saying out loud on a page like this one, because a statistic with an official sounding source attached is more persuasive than the Civil Code and less true. The articles above are the rules. They can be read in a few minutes, by anybody, free.

Where to read this at the source

The Civil Code of Quebec is published free at LegisQuebec, article by article, in both languages. Articles 2408, 2410, 2422, 2424, 2449, 2455 and 2459 are the ones this article rests on.

The consumer pages on buying insurance, on the prior notice of replacement, and the register of firms and individuals authorized to practise are published by the Autorite des marches financiers. Every source named here was read on 23 September 2026 and every one of them can be revised without notice.
