The contestability period, and what happens when a claim is denied

Under the hood · 8 min read · Published October 17, 2026 · Last updated October 17, 2026

For the first two years of a Canadian life insurance policy, the insurer holds a right it later gives up: the right to reopen the application, compare it against the medical and other records, and refuse to pay if the application contained a material misstatement. That window is called the contestability period. It is not a waiting period and it does not suspend coverage; most claims inside it are paid. But it explains why early claims are investigated more closely, why application accuracy matters so much, and what a beneficiary can actually do if a denial arrives. This guide explains the window, separates it from two other two-year rules it is routinely confused with, and sets out a numbered escalation procedure. It is general information only, not legal advice about any specific claim.

What the contestability period is

In most Canadian life and health insurance policies, the contestability period lasts two years from the date the policy takes effect. During that window, the insurer may review and investigate the accuracy of the information given in the application. If it discovers that information was omitted, misstated, or misrepresented, it can deny a claim or void the policy. Ontario legal guidance on denied claims describes the same boundary from the statute side: an insurer may use non-disclosure or misrepresentation to nullify coverage only within two years of the date the contract came into effect, or was reinstated, unless there was fraud.

Two features of the window surprise most people. The first is that intent does not matter inside it. An honest mistake, a forgotten diagnosis, a condition the applicant genuinely believed was too minor to mention: any of these can support a denial if the missing fact was material. The second is that the cause of death does not need to match the missing fact. Guidance on the period states the point directly: the reason for the loss does not need to be related to the misrepresentation, so an unrelated cause of death can still lead to a denied claim when a material omission is found. Materiality is judged by the reasonable insurer standard described in the Ontario guidance: would the fact, properly disclosed, have mattered to a reasonable insurer deciding whether and on what terms to issue the policy? The applicant’s own view of whether the fact seemed important is not the test.

Three different clocks, often confused

Keeping the three apart prevents the two most common errors in online discussions of denied claims: treating the suicide clause as part of contestability (it is a separate exclusion with its own clock), and assuming a family has unlimited time to file because a policy is old (the filing window is contractual and much shorter). Two more facts from the Canadian Life and Health Insurance Association’s consumer guide are worth holding alongside the table: most insurers pay interest on a claim from the date of death, and, as a rule, the death benefit of a life insurance policy is not taxable in Canada.

Material facts, honest mistakes, and fraud

The word that decides most contests is material. Medical history, age, and occupation are the clearest examples of facts a reasonable insurer would want. A misstatement that would not have changed the underwriting decision is a weaker ground for denial than one that would have changed the price, the amount, or the decision to issue at all. That is why the practical advice at application time is unglamorous and absolute: disclose everything asked, including anything that feels minor, and let the insurer decide what matters. A condition disclosed and assessed before issue becomes part of the bargain the insurer priced; the same condition discovered after an early death becomes the centre of a contest.

Fraud is the permanent exception. Where a misrepresentation is fraudulent, meaning an intentional deception, the Ontario guidance states there is no time limitation within which the insurer can void the contract. The incontestability protection that arrives at the two-year mark covers non-fraudulent error; it was never designed to protect a lie. The practical line for applicants is therefore not “small versus large” but “honest versus deliberate,” and only the honest side of that line gains protection with time.

When the clock restarts

The two years are counted from more than one possible starting line. Ontario guidance measures the insurer’s window from when the contract came into effect or was reinstated. Broker guidance on denied claims says the same thing in operational terms: if a lapsed policy is reinstated, a fresh contestability period typically applies from the reinstatement date, depending on the contract. That connects this topic to premium discipline. Most Canadian insurers allow a grace period, typically 30 days, for a late premium before a policy lapses; after a lapse there is no coverage at all until reinstatement, and reinstatement can require updated health information. A policyholder who lets a policy lapse and reinstates it has therefore done two things at once: accepted a gap with no coverage, and restarted the two-year window during which application accuracy can be re-litigated, now including the reinstatement application itself. Keeping premiums current is claim protection, not just bookkeeping.

It is equally important to say what the two-year mark does not change. Grounds that live in the contract itself are unaffected by it: a policy that lapsed for non-payment, a term that expired, or an exclusion that applies to the circumstances of death can support a denial in year ten just as in year one. Contestability governs one ground of denial, misrepresentation, not every ground.

If a claim is denied: a numbered procedure

A denial is a decision, not the end of the process. Beneficiaries can work through the following steps in order.

1. Get the denial in writing, with the exact policy provision and the specific application statement the insurer says was misstated or omitted. A phone explanation is not enough to appeal against.
2. Assemble the file before responding: the policy and application copy, the denial letter, medical or other records that bear on the disputed fact, and a dated timeline of the application, any reinstatement, and the claim.
3. Check the dates first. Was the death, and the insurer’s discovery, inside the two years from issue or reinstatement? Is the insurer alleging fraud, which has no time limit, or non-fraudulent error, which generally does? Date errors by an insurer are worth identifying early.
4. Use the insurer’s internal complaints process, in writing, addressing the denial point by point: what was actually disclosed, what the records show, and why the fact was or was not material. Keep copies of everything sent.
5. Ask for the insurer’s final position letter when the internal process concludes. The OmbudService for Life and Health Insurance states that this letter, the insurer’s written final decision, is required before it can review the complaint.
6. Take the complaint to the OmbudService for Life and Health Insurance (OLHI), the free, independent dispute-resolution service for life and health insurance in Canada. OLHI cannot review a denied claim that has not completed the insurer’s internal process, which is why step 5 unlocks this one. Its recommendations are not legally binding, but they carry real weight with insurers.
7. For a large or complex dispute, get legal advice promptly rather than at the end. Court actions against insurers carry limitation periods, and a lawyer who handles denied life insurance claims can assess both the materiality argument and the deadline picture.

What success looks like: the insurer’s stated ground is identified precisely, the two-year and fraud questions are answered from dated documents, the internal process is completed and documented, and the file reaches OLHI, if needed, with a final position letter attached. A complaint that skips the internal process cannot be reviewed by OLHI, however strong its merits.

Decision framework: reading a denial letter

Four questions sort most denial letters. What ground is cited? Misrepresentation points to contestability; lapse, expiry, and exclusions point to the contract, and the two-year analysis does not apply to them. Where are we on the clock? Inside two years from issue or reinstatement, non-fraudulent error is contestable; outside it, only fraud generally remains. Was the fact material? Ask what a reasonable insurer would have done with the true fact at application: different price, different amount, or no policy at all. What does the paper show? The signed application, any paramedical notes, and the insurer’s own file are the evidence; recollections come second. A denial that survives all four questions is a strong candidate for legal advice; one that fails the dates or the materiality question is a strong candidate for the complaints process and OLHI.

Questions people commonly ask

Does a death in the first two years mean the claim will be denied? No. It often means the insurer reviews the claim more closely and payment can take longer while records are pulled. Contestability is a right to investigate and, where a material misstatement is found, to deny; it is not an automatic denial.

Can an insurer deny a claim after two years? Yes, on grounds that do not expire: fraud, and contract grounds such as lapse, an expired term, or an applicable exclusion. What generally expires at two years is denial based on non-fraudulent application error.

Is the suicide clause part of contestability? No. It is a separate provision. The CLHIA consumer guide states that individual policies normally contain a two-year suicide clause, that a suicide death within two years is not paid, and that after two years it is paid.

Who pays for an OLHI review? The service is free to the consumer. OLHI describes itself as free, impartial help with life and health insurance complaints, available once the insurer’s internal process is finished and a final position letter has been issued.
