A Toronto couple purchased travel health insurance before their two-week vacation to Mexico. When one of them required emergency surgery abroad, they discovered their C$15,000 policy covered only C$3,200 of the C$18,000 bill. The reason: a medication they had been taking for high blood pressure, which their doctor had adjusted six weeks before departure, triggered a pre-existing condition exclusion they had not read in the policy wording. They returned home facing C$14,800 in medical debt, a hard lesson in the coverage gaps that catch thousands of Canadian travellers each year.

Provincial health plans provide minimal coverage outside Canada. According to the Financial Consumer Agency of Canada, most provinces reimburse emergency medical costs abroad at the rate they would pay at home, which is often a fraction of what foreign hospitals charge (FCAC, 2024). Travel health insurance is essential, but only if you understand what it actually covers and where the exclusions hide.

1. Pre-Existing Condition Exclusions

Most travel health insurance policies exclude coverage for any medical condition you had before the trip, and the definition of “stable” varies widely. A pre-existing condition is typically considered unstable if you have had any change in medication, dosage, treatment or symptoms within a specific period before departure, often 90 days but sometimes as little as 30 days. A routine prescription adjustment, even if your doctor considers it minor, can void your coverage for any condition related to that medication. Always disclose every medical condition and medication to your insurer, read the stability period in your policy wording, and confirm in writing what is covered before you travel.

2. Adventure and High-Risk Activity Exclusions

Standard travel health insurance often excludes injuries from activities the insurer deems high-risk. Scuba diving below a certain depth, skiing off-piste, motorcycling without a valid Canadian motorcycle licence, bungee jumping, and even some organized adventure tours may not be covered unless you purchase a rider or a specialized policy. The Insurance Bureau of Canada notes that many travellers assume recreational activities are covered by default, only to discover the exclusion when they file a claim (IBC, 2024). If your trip includes anything beyond sightseeing and swimming, read the exclusions list and add the appropriate coverage.

3. Age Limits and Automatic Deductibles

Many insurers impose age-based restrictions. Travellers over 60 or 65 may face automatic deductibles (often C$1,000 to C$3,000 per claim), higher premiums, shorter maximum trip durations, or stricter pre-existing condition clauses. Some policies cap coverage at a lower amount for older travellers or require a medical questionnaire before issuing the policy. If you are over 60, compare policies designed for seniors and confirm the deductible, coverage limit and trip duration allowable for your age before you buy.

4. Trip Duration and Extension Limits

Travel health insurance is sold by trip length: single-trip policies cover a specific departure and return, while annual multi-trip policies cover multiple trips within a year, each subject to a per-trip maximum duration (commonly 30, 60 or 90 days). If you extend your trip beyond the original end date and do not notify your insurer to purchase additional coverage before the original policy expires, you are uninsured for the extension. Extending coverage after the original expiry is often impossible, and a medical event during the extension is not covered.

5. Geographic Exclusions

Some policies exclude coverage in specific countries or regions the insurer considers high-risk due to political instability, conflict or infectious disease outbreaks. If the Government of Canada has issued a “avoid all travel” advisory for your destination, most insurers will not cover you, and some will cancel your policy if you enter that area. Always check the Government of Canada travel advisories and your policy’s geographic exclusions before you depart, and confirm your destination is covered.

6. Failure to Read the Policy Wording

The policy wording is the legal contract. The summary brochure and the sales agent’s verbal assurances are not binding. Coverage details, exclusions, deductibles, claim procedures and the definition of key terms such as “emergency,” “stable” and “medically necessary” are in the policy wording only. Canadians frequently purchase travel health insurance online or through a travel agent, receive a confirmation email and never open the attached policy document. If a claim is denied, the insurer refers to the policy wording you received (and presumably read) when you purchased the coverage. Read the full policy before you travel, and if anything is unclear, contact the insurer for clarification in writing.

7. Assuming Provincial Health Coverage Extends Abroad

Provincial health insurance plans do provide limited emergency medical coverage outside Canada, but the reimbursement is capped at the amount the province would pay for the same service at home. A hospital stay in the United States that costs US$50,000 (roughly C$68,000) might be reimbursed by your provincial plan at the rate of C$1,500, leaving you with a C$66,500 bill. The Financial Consumer Agency of Canada recommends that all Canadians travelling outside their home province or outside Canada carry private travel health insurance, as provincial coverage is insufficient for foreign medical costs (FCAC, 2024).

What to Do Before You Travel

Before you purchase travel health insurance, list every medical condition you have or have had, every medication you take (including over-the-counter and supplements), and any recent changes in treatment or symptoms. Disclose everything to the insurer, even if you think it is minor. Read the full policy wording, not just the summary. Confirm the stability period for pre-existing conditions, the activities covered, the trip duration, the deductible, the coverage limit and the geographic area. If you have any doubt, ask the insurer for written clarification. Foundational texts such as Introduction to Business explain that insurance contracts are based on utmost good faith: both parties must disclose all material facts honestly, and failure to do so voids the contract.

Travel health insurance is essential protection, but only if you buy the right policy and understand what it actually covers. The couple who faced C$14,800 in medical debt learned that lesson the hard way. Read the policy, disclose your full medical history, and confirm your coverage in writing before you depart.
