PetQuick Answer
No Canadian pet insurer covers pre-existing conditions. If your pet was diagnosed with, treated for, or showing symptoms of a condition before your policy started — including during the waiting period — that condition is excluded for the life of the policy. There are limited exceptions for "curable" conditions that have been symptom-free for 12+ months at some insurers, but the safe planning assumption is: anything documented before enrollment is excluded.
What counts as pre-existing
Insurers use a broad definition. A condition is typically considered pre-existing if, before your policy effective date or during a waiting period:
- A veterinarian diagnosed it
- A veterinarian treated it (medication, surgery, therapy)
- Your pet showed clinical signs or symptoms — even if undiagnosed
- It's noted anywhere in your pet's medical records
That last one matters. Vet notes like "owner reports occasional limping" can be enough to exclude a future cruciate or arthritis claim, even if no formal diagnosis was made.
Why insurers do this
Pet insurance, like all insurance, prices the risk of future unknown events. If a condition is already in progress, it's no longer a risk — it's a certainty. Covering pre-existing conditions would mean insurers paying out predictably for every new policy, which would make the product unaffordable for everyone.
This is universal across the industry. There is no Canadian insurer that covers pre-existing conditions in the way the marketing of "comprehensive coverage" might suggest.
"Curable" vs "incurable" — the only meaningful exception
Some Canadian insurers distinguish between:
- Curable conditions (e.g. an ear infection, a UTI, a wound that healed). After a defined symptom-free period (often 12+ months), some insurers will treat these as no longer pre-existing.
- Incurable conditions (e.g. allergies, diabetes, arthritis, cancer, dysplasia). Permanently excluded once documented.
Petsecure, Pets Plus Us, and Trupanion handle this differently. Read each policy's specific definition of pre-existing — it's the single most important section of the document.
Which Canadian insurers cover curable pre-existing conditions?
Every Canadian insurer excludes conditions that are genuinely pre-existing — that part is universal. Where they differ is the curable-condition exception: whether a one-off, fully-resolved problem can become claimable again after a symptom-free period. This is the single most useful distinction if your pet has any minor history on record.
| Insurer | Curable pre-existing conditions |
|---|---|
| Fetch | Can be covered after 12 months symptom-free and treatment-free — the standout for curable conditions |
| Trupanion | No curable pathway — all pre-existing conditions are permanently excluded |
| Petsecure | No publicized curable pathway — verify the policy wording |
| Pets Plus Us | No publicized curable pathway — verify the policy wording |
| Sonnet | No publicized curable pathway — verify the policy wording |
| Furkin | No publicized curable pathway — verify the policy wording |
| CAA | Runs on the Pets Plus Us platform — verify the policy wording |
| PC | Runs on the Pets Plus Us platform — verify the policy wording |
| PHI Direct | Petline-underwritten brand — verify the policy wording |
All insurers above exclude conditions that are pre-existing — this column is specifically about the curable-condition exception. "Verify the policy wording" means the insurer doesn't clearly publicize a curable-condition window, not that one definitely doesn't exist. Confirm the exact definition with the insurer before relying on it; terms change. (Editorial comparison, not advice.)
The practical takeaway: if your pet has a minor, fully-resolved issue on record (a past ear infection, a single UTI), Fetch's 12-month curable window is the clearest route to getting it covered again. If your pet's history is clean, this distinction matters less — but it's still worth knowing before you switch insurers.
Bilateral exclusions: the trap most owners miss
Many insurers treat paired body parts as one condition. If your dog ruptured one cruciate ligament before enrollment, the other knee can also be excluded — because both are considered the same condition.
Same logic applies to:
- Hips (both sides)
- Elbows (both sides)
- Eyes (both sides)
- Ears (both sides)
Confirm with your specific insurer whether bilateral exclusions apply to you. If your pet has an existing one-sided issue, this is a major consideration in choosing a policy.
What this means practically
- Enrol while your pet is young and healthy. The earlier you enrol, the fewer things will be pre-existing.
- Get a thorough vet exam right before enrolling. Then enrol. Anything diagnosed after the policy starts is covered (subject to waiting periods); anything diagnosed before is excluded forever.
- Don't switch insurers casually. If you switch, every condition diagnosed under your previous policy is pre-existing on the new one. You essentially restart at a worse position.
- Document everything. If you ever need to dispute a pre-existing exclusion, you'll want clear records of when symptoms first appeared.
What about the waiting period?
The waiting period (typically 2–30 days depending on condition type) is part of the pre-existing definition. A condition that develops during the waiting period is treated as pre-existing. This is why insurers don't sell coverage that starts immediately — they need a buffer against people enrolling for a current problem.
If you have an older pet or a pet with documented conditions
Insurance is still often worth considering — but with realistic expectations:
- Coverage applies only to new conditions that emerge after enrollment
- Premiums are higher
- Some insurers cap enrollment age
For an older pet, get quotes anyway. A capped, accident-only, or comprehensive-with-exclusions policy may still be worth the monthly premium for the events you can't predict.
