Trip Cancellation vs. Trip Interruption Insurance: What Each One Covers

This is general information, not a guarantee of coverage. Policy terms, limits and exclusions differ between insurers, so confirm the details of any policy with an advisor before you buy it.
Quick answer: trip cancellation insurance applies only when you cancel your trip before it starts. Trip interruption insurance applies after you have left, and reimburses the unused part of your trip if an unforeseen incident forces you to come home early. The Government of Canada's travel insurance guidance describes them as separate products and advises buying before you leave. Both depend on a covered reason in the policy, and neither is an automatic refund: Air1's travel page says cancellation is not automatically refundable, and that the reason, timing, limits, exclusions and documents all matter.
What each one means
The two words describe different moments of the same trip.
Trip cancellation covers the period between booking and departure. The Government of Canada says cancellation coverage "applies only when you cancel your trip before it starts". If something happens that the policy recognizes as a covered reason, the benefit may reimburse eligible non-refundable costs you have already paid, such as flights, tours or accommodation. Air1's travel page says the same thing in its refund answer: cancellation cover may reimburse eligible non-refundable costs when you cancel for a reason covered by the policy.
Trip interruption covers the period after you have left home. According to the Government of Canada, it reimburses the unused part of your trip if an unforeseen incident forces an early return. It is different from medical travel insurance, which pays for health care. Air1's travel page lists the combined feature as "Trip Interruption or Cancellation" and describes it as a way to recover costs for unforeseen changes to your itinerary.
Many plans bundle the two, which is why you will often see the phrase "trip cancellation and interruption insurance". Do not assume yours does. Air1's page says that depending on the policy, travel insurance may include trip cancellation or interruption, so check that both are in the plan you are quoted.
Side by side
The "covered reason" is the whole question
Most of the confusion about these benefits comes from one point: you are not insured against cancelling for any reason, you are insured against cancelling for the reasons the policy names. Air1's travel page says exclusions "vary by policy and may involve pre-existing medical conditions, certain activities, destinations, advisories or events that were known before purchase".
Three things decide whether a claim fits:
1. The reason. Read the list of covered reasons. If your reason is not on it, the benefit may not respond.
2. The timing. When you booked, when you bought the insurance, and when the event happened can all matter. An event that was already known before you bought the policy is a common exclusion.
3. The paperwork. Air1's page notes that documents matter. Keep receipts, booking confirmations and any supporting letters.
The Financial Consumer Agency of Canada defines exclusions plainly as "things that your insurance policy doesn't cover", and gives a travel example: a policy may exclude claims if you travel to a high-risk country. Build that habit in: before you buy, ask what the policy excludes, in writing.
Pre-existing medical conditions
For many travellers this is the exclusion that matters most. The Government of Canada advises you to get written confirmation that your condition is covered, because without it a claim could be voided under a pre-existing condition clause. It also notes that coverage may depend on a stability period, during which your condition, symptoms and medications must not change.
That guidance appears in the context of travel health insurance, but the same questions are worth asking about cancellation and interruption benefits: if a health condition could force you to cancel or cut a trip short, ask exactly how the policy treats it, whether a stability period applies, and whether it applies to trip benefits as well as medical benefits.

"Cancel for any reason": ask, do not assume
Some insurers offer an optional upgrade that lets you cancel for reasons the standard plan does not cover. Air1's travel page does not describe an option like this. If it matters to you, ask your advisor whether one is available for your trip, whether it reimburses all or only part of your costs, whether it must be bought soon after your first deposit, and what it costs. Do not assume it exists, and do not assume it pays everything.
How much trip cost are you actually protecting?
The simplest way to size cancellation cover is to add up what you could not get back. Air1's domestic-travel guide suggests the same starting point: total your non-refundable deposits, flights and penalties. Include:
• Flights and airline change fees you could not recover
• Accommodation and tour deposits
• Prepaid activities, passes and event tickets
• Anything you booked for other people in your party
Compare that total with the maximum benefit in the plan. Air1's page says cost depends on destination, trip length, traveller details, health information, selected coverage, limits and deductibles, so a higher benefit limit will usually be priced differently from a lower one.
The Financial Consumer Agency of Canada explains a deductible as the amount of your claim that you must pay before the insurer pays the rest. The Government of Canada lists whether there is a deductible, and how much it is, among the questions to ask an insurer.
Check what you already have
Before you buy another policy, check whether a credit card, a group benefits plan or your travel supplier already provides any trip cancellation or interruption benefit, and what it requires. It is fine to have more than one source of cover, but you should know what each one pays so you do not pay twice for the same protection, or assume one plan covers a gap that it does not.
Questions to ask before you buy
The Government of Canada recommends asking the insurer for a written explanation if anything is unclear. Use these questions as a starting point:
1. Does this plan include both cancellation and interruption, or only one?
2. Which reasons are covered, and where is the list in the policy?
3. What are the maximum benefits for each, and do they cover everyone on the booking?
4. How does the policy treat pre-existing medical conditions, and is there a stability period?
5. Is there a deadline after booking to buy this cover?
6. Does the plan cover your destinations, and any activities such as skiing or scuba diving?
7. What documents will a claim need?
8. Is there a deductible?
9. Is a cancel for any reason option available, and what does it reimburse?
If you need to claim
Contact the insurer or your advisor as soon as possible after the event rather than waiting until you are home. Air1's travel page says its support team will assist with the required documentation and the claims process. In the meantime, keep:
• Booking confirmations and receipts for non-refundable costs
• Written confirmation from airlines, hotels or operators of what they will and will not refund
• Any medical or official documents that explain the reason for the change
• Your policy number and the policy wording you bought
The Government of Canada also suggests keeping a copy of your insurance details with someone at home, which makes it easier for them to help if you need to claim from abroad.
