Travel Insurance with
Pre-Existing Conditions
Quick Answer
Most Canadian travel insurers will cover a pre-existing condition that has been “stable” for a set period, commonly 90 to 180 days, sometimes longer with age. Stability is defined by the policy, not by how well you feel: a dose change, new test, or new symptom can reset the clock. Full, accurate disclosure is what keeps the coverage enforceable.

1 What Counts as a Pre-Existing Condition
A pre-existing condition is any medical condition that existed before your coverage started, whether or not it has been formally diagnosed. Insurers look at the period before the policy effective date, and they look at treatment, medication, testing, and symptoms, not just diagnoses.
- Conditions you take regular medication for, such as hypertension or type 2 diabetes
- Conditions under investigation, even without a final diagnosis
- Conditions treated in the past that could recur
- Symptoms you have experienced but not yet reported to a doctor
“Undiagnosed” is not the same as “not pre-existing.” If you were investigating chest pain before departure, a cardiac claim abroad will be assessed against that history.
2 The Stability Period: The Rule That Decides Everything
Nearly every Canadian travel policy hinges on stability. The insurer picks a look-back window, often 90, 180, or 365 days before the effective date, and asks whether your condition changed during it. If it did not change, the condition is typically covered. If it did, the condition is typically excluded, though the rest of the policy still stands.
Usually still stable
Likely covered
Same medication, same dose, no new symptoms, no new tests or specialist visits during the look-back window.
Grey area
Depends on wording
A brand-to-generic switch, a routine dose adjustment, or a scheduled monitoring test. Some insurers forgive these; others do not.
Resets the clock
Likely excluded
New medication, increased dose, new symptom, hospital visit, or a pending test result during the look-back window.
Never covered
Excluded
Travel undertaken against medical advice, or travel for the purpose of obtaining treatment abroad.
Because insurers define stability differently, the same traveller can be fully covered by one carrier and excluded by another on the same day. Matching the wording to your history is the entire job of a broker here.
3 Common Look-Back Windows
Windows vary by insurer, by plan tier, and by your age at application. The table below shows the shape of the market rather than any single carrier's current wording, always confirm on a live quote.
| Look-Back Window | Who It Typically Applies To | Practical Effect |
|---|---|---|
| 90 days | Younger travellers, standard plans | Easiest to satisfy after a recent medication change |
| 180 days | Common default across many plans | A dose change five months ago can still matter |
| 365 days | Older applicants or enhanced-coverage tiers | Requires a full year of unchanged treatment |
| No coverage of pre-existing | Some budget tiers | Cheapest premium, but the condition is simply excluded |
| Illustrative market shapes only. Stability definitions and windows change; confirm the current wording on your quote and certificate. | ||
4 How Common Conditions Are Usually Treated
The following reflects general market behaviour, not a guarantee. Every application is assessed individually.
| Condition | Typical Outcome When Stable | What Usually Causes Trouble |
|---|---|---|
| Hypertension | Commonly covered | A dose change inside the look-back window |
| Type 2 diabetes | Commonly covered | New insulin, or an A1C-driven treatment change |
| High cholesterol | Commonly covered | Recently started or changed statin |
| Thyroid conditions | Commonly covered | Recent dosage adjustment |
| Asthma / COPD | Insurer-dependent | Recent exacerbation, new inhaler, or oxygen use |
| Cardiac history | Insurer-dependent | Any stent, bypass, or medication change; windows are strictest here |
| Cancer history | Insurer-dependent | Active treatment or recent recurrence |
| Pending investigations | Usually excluded | Any test whose result is unknown at departure |

5 How to Disclose Properly
Under-disclosure is the most expensive mistake in travel insurance, because it can void a claim you have otherwise paid for correctly. Over-disclosure costs you nothing.
- Work from your pharmacy printout, not your memory. It has dates and dose changes on it.
- Include everything from the look-back window, including tests that came back normal.
- Read the questionnaire literally. “Treated for” usually includes medication you take daily without thinking about it.
- If a question is ambiguous, ask the advisor and note the answer before you submit.
- Re-check after any medical change before departure. A change between purchase and departure can matter.

6 Why Pre-Existing Claims Get Denied
- The condition was not stable during the look-back window
- The questionnaire answer did not match the medical record the insurer obtained
- A pending test result existed at departure and was not declared
- Travel was undertaken against medical advice
- The claim was for treatment sought abroad rather than a genuine emergency
If a claim is declined, you are entitled to the reason in writing and to an appeal. The process is set out in our travel insurance claim guide.
7 How to Shop When You Have a Condition
- Do not filter by price first. Filter by which insurers can cover the condition, then compare price among those.
- Ask for the stability definition in writing for each quote you are comparing.
- Compare at identical medical maximums and deductibles so the numbers mean something.
- Consider a higher deductible rather than a plan that excludes the condition outright.
- Buy early enough that a scheduled test does not land inside the window before departure.
If your condition changed recently, a shorter look-back window is worth more than a lower premium. A 90-day window can cover what a 180-day window excludes.

8 Frequently Asked Questions
Can I get travel insurance with a pre-existing condition in Canada?
Usually yes. Most Canadian travel insurers cover pre-existing conditions that have been stable throughout the policy's look-back period, commonly 90 to 180 days. The condition is assessed on the application, and accurate disclosure is required.
What does 'stable' mean in travel insurance?
Stable generally means no change to the condition during the look-back window: no new diagnosis, no new or increased medication, no new symptoms, no new tests or specialist referrals, and no hospitalisation. Each insurer publishes its own precise definition in the policy wording.
Does a change in medication affect my travel insurance?
It can. A new medication or an increased dose usually restarts the stability clock for that condition. A brand-to-generic substitution at the same dose is treated more leniently by some insurers than others, so confirm the wording.
What happens if I do not declare a condition?
The insurer can deny a related claim and, in some cases, void the policy and refund only the premium. Non-disclosure is the most common reason large travel medical claims fail. Declaring more than necessary costs nothing.
Is travel insurance more expensive with pre-existing conditions?
Sometimes. Depending on the insurer, a condition may be covered at standard rates, surcharged, or excluded. Pricing factors are broken down in our travel insurance cost guide.
Do I need a medical exam to buy travel insurance?
Rarely. Most Canadian travel insurance is underwritten from a medical questionnaire rather than an examination. The insurer may still request medical records at claim time, which is why the questionnaire must match your record.
Are pre-existing rules the same for Super Visa and visitors insurance?
The concept is the same, but windows and wording differ. See Super Visa pre-existing conditions and visitors insurance pre-existing conditions.
