Pre-existing Condition Travel Insurance Review and Comparison for Canadians
Last reviewed: October 2026
How your insurer treats a pre-existing condition can decide whether a claim is paid. Understanding how it defines the term, and what "stable" means, before you buy can help you avoid an uncovered bill abroad.
What counts as a pre-existing condition?
A pre-existing medical condition is a condition, illness or injury that exists before your coverage takes effect. For emergency medical coverage that is typically the date you depart. For trip cancellation coverage it is typically the date you buy the insurance or make your first trip payment. The condition may be minor, ongoing or even healed, and it may or may not still need treatment.
What does "stable" mean?
Most policies cover a pre-existing condition only if it has been stable for a defined period before your coverage starts. Insurers define stable in their policy wording, but the criteria are usually similar. For example, Ontario Blue Cross explains that during the stability period you must not have received a new prescription or treatment, taken a new drug, had a change in the dosage of an existing medication, or be waiting for treatment, surgery or test results. Insurers commonly add that there must be no new symptoms, no worsening of existing symptoms, no hospitalization or specialist referral, and no pending tests or test results. Some policies carve out routine adjustments, such as regular insulin or warfarin (Coumadin) dosing based on blood tests, or switching a brand-name drug to the same dose of a generic. Other criteria may apply, so read your own policy.
How long is the stability period?
It varies by insurer, by your age, and by the type of coverage. As one published example, Ontario Blue Cross requires an emergency medical condition to be stable for three months before departure if you are 54 or younger and six months if you are 55 or older, and three months for trip cancellation and interruption coverage. Other insurers commonly use 90 or 180 days, and some plans offer shorter periods (for example 7, 30 or 90 days) or waive the pre-existing condition wording altogether, while some snowbird plans require longer periods for extended trips. Always check the period in the specific quote or policy you are considering.
Because a short period at one insurer can be much longer at another, comparing stability periods is just as important as comparing coverage limits.
If your condition is not stable
An unstable condition, and anything directly related to it, will usually be excluded. That does not make the policy worthless. As Ontario Blue Cross notes, you can still be covered for events unrelated to the excluded condition. Someone with unstable diabetes, for example, would still have emergency medical coverage for an unrelated accident or injury.
Note that no policy will cover a condition if you are currently on a waiting list for surgery, a specialist consultation or medical tests. Those need to be completed first.
Your options if you have a pre-existing condition
A standard policy with a stability requirement. If your condition has been stable for the required period, this is often the simplest route.
A policy with a shorter stability period or an optional rider. Some insurers offer shorter stability periods, or let you reduce the period for an additional premium, usually with eligibility limits. Some plans also base eligibility partly on how many medications you take rather than a list of conditions, which can suit people with several well-managed conditions.
Choosing not to insure the pre-existing condition. If your conditions are well managed and you accept the risk, some plans let you exclude them, which usually lowers the cost. You remain covered for new and unrelated emergencies.
Direct medical underwriting. Some insurers will review your full medical history, much like a life insurance application. If you qualify, there may be no stability period at all, but not everyone qualifies.
Emergency evacuation and repatriation only. These cover medical transport, not hospital or physician bills, so they are not a substitute for emergency medical insurance.
Before you buy: a checklist
Write down every condition, medication and recent appointment, and check each against the stability definition.
Compare the stability period for your age, not just the headline coverage.
Declare everything on the health questionnaire. Leaving something out can void a claim. Many insurers require a questionnaire for travellers over 54, and a higher-risk rating with one insurer may not apply with another, so compare more than one.
Ask whether a medication dose change, new prescription or pending test result affects your coverage.
If your health changes between purchase and departure, contact the insurer before you travel.
Keep the policy wording and your health declaration with your travel documents.

Frequently asked questions
Is a pre-existing condition always excluded?
No. Many policies cover a stable pre-existing condition. They exclude one that has not been stable for the required period.
Does changing my medication affect coverage?
It can. A change in dosage or a new prescription during the stability period may mean the condition is no longer considered stable under some policies.
What if my condition becomes unstable after I buy?
Contact your insurer before you leave. Coverage may be affected, and you may need to update your health declaration.
Will I still be covered for other emergencies?
Generally yes. An excluded pre-existing condition does not remove coverage for unrelated events such as an accident.
