Pet insurance coverage explained, in plain English

The three coverage types

1. Accident-only

Covers injuries — broken bones, lacerations, foreign object ingestion, poisoning, hit-by-car. Does not cover any illness (cancer, diabetes, heart disease, allergies, infections, etc.).

Best for: young, indoor-only, low-risk pets where the owner can self-insure for illness. Not recommended for most owners — illness is statistically more expensive over a lifetime than accidents.

2. Comprehensive (accident + illness)

The Canadian default. Covers both accidents and illnesses, including:

• Cancer treatment (surgery, chemo, radiation)
• Surgery for all eligible conditions
• Diagnostics (bloodwork, X-rays, ultrasound, MRI)
• Hospitalization
• Prescription medications (when prescribed for an eligible condition)
• Specialist consultations
• Hereditary and congenital conditions (after waiting period)

Best for: almost everyone. This is what most owners actually need.

3. Comprehensive + wellness add-on

Adds preventive and routine care:

• Annual checkups
• Vaccinations
• Dental cleaning
• Parasite prevention
• Spay/neuter (sometimes)
• Microchipping

Best for: owners who want predictable monthly costs that cover routine care, or owners who routinely use higher-cost preventive services. Note that wellness add-ons rarely "pay for themselves" mathematically — the math works out roughly even — but they smooth out the budget.

What's usually NOT covered

• Pre-existing conditions — universally excluded. Anything diagnosed, treated, or showing symptoms before your enrollment date.
• Cosmetic procedures — ear cropping, tail docking, dewclaw removal.
• Breeding-related expenses — pregnancy, whelping, fertility treatments.
• Behavioural training
• Boarding and grooming
• Food and supplements (unless prescribed for a medical condition)
• Routine care unless you have the wellness add-on

How deductibles work

The deductible is what you pay before the insurer reimburses anything. Two main structures in Canada:

• Annual deductible — pay it once per policy year. Reset every year. Used by Petsecure, Pets Plus Us, and most other Canadian insurers.
• Per-condition deductible — pay it once per condition, for the lifetime of the policy. Used by Trupanion.

For chronic conditions (allergies, arthritis, diabetes), per-condition deductibles compound in your favour over time. For one-off events, annual deductibles are simpler.

How reimbursement works

Most Canadian insurers reimburse a fixed percentage of the eligible bill after the deductible:

• 70% — cheapest tier, lowest reimbursement
• 80% — standard tier
• 90% — highest tier (Trupanion's flat rate)

Higher reimbursement = higher monthly premium. Most owners are best served by 80% or 90% — the lower tiers leave you exposed on the largest bills.

Waiting periods

You can't enrol today and claim tomorrow. Standard waiting periods:

• Accidents: typically 2–14 days
• Illnesses: typically 14–30 days
• Orthopedic conditions (cruciate, dysplasia): often 6 months on some insurers

Anything that happens during the waiting period is excluded as "pre-existing."

The exclusions that actually trip people up

1. Bilateral exclusions — some insurers treat both knees as one condition. If one cruciate ruptured before enrollment, the other one is also excluded.
2. Curable vs incurable pre-existing — some insurers will cover a previously-resolved condition if it's been symptom-free for 12+ months. Others won't. Read the policy.
3. Behavioural exclusions — anxiety, aggression, separation issues are usually excluded.
4. Alternative therapies — acupuncture, chiropractic, physiotherapy may or may not be covered. Check.

How to actually compare plans

Don't compare on monthly premium alone. Compare on:

1. Annual payout cap — capped policies fail exactly when you need them (cancer, complex surgery)
2. Reimbursement rate — 80% vs 90% matters on a $10,000 bill
3. Deductible structure — annual vs per-condition has long-term consequences
4. Hereditary condition coverage — confirm it's included, not a paid add-on
5. Direct vet pay availability — saves you the float on big bills
