Trupanion vs Sonnet: which Canadian plan fits?

By PetAssured Editorial Team Last reviewed : June 8, 2026 7 min read

Quick Answer

Trupanion and Sonnet solve different problems. Trupanion is the catastrophic-coverage pick — 90% flat reimbursement, an unlimited annual payout, a per-condition deductible, and direct vet pay. Sonnet (underwritten by Petline) is the simple, fully-online pick — up to 80% reimbursement, a capped annual limit, and included dental (annual cleanings on its Comprehensive plan). If your priority is the highest possible ceiling for a major illness or surgery, Trupanion. If you want an easy online plan with routine dental built in, Sonnet — where it's available in your province.

The honest verdict

Our Recommendation

Choose Trupanion if your priority is the catastrophic tail — a torn cruciate, cancer, or a chronic condition where an unlimited cap and per-condition deductible pay off, and where direct vet pay matters.

Choose Sonnet if you want a simple online plan with everyday value — included annual dental and an easy digital experience — and it's offered in your province. Just note the 80% reimbursement ceiling and capped annual limit versus Trupanion.

Frequently asked questions

Is Sonnet cheaper than Trupanion?
Often, because Sonnet caps reimbursement at 80% and its annual payout is limited, while Trupanion's 90% flat reimbursement and unlimited cap cost more. The only way to know for your pet is to get both quotes for the same breed, age, and postal code.
Who underwrites Sonnet pet insurance?
Petline Insurance Company — the same underwriter as Petsecure. Trupanion underwrites its own policies.
Which is better for a high-risk breed?
For breeds prone to expensive, recurring conditions, Trupanion's unlimited cap and per-condition deductible are usually the safer structure. See our breed guides for risk profiles.
Does Sonnet offer direct vet pay?
No — Sonnet is a reimbursement model; you pay the vet and claim afterward. Trupanion offers direct pay at VetDirect-enabled clinics.
