Pre-existing conditions, waiting periods, and the clock that decides claims

The gap between buying a policy and coverage starting: commonly 2-15 days for accidents, about 14 days for illnesses, and up to 6 months for hip and knee conditions - though some insurers waive the orthopedic wait with a vet exam completed within the first 30 days. A condition that appears during a wait counts as pre-existing.

Pre-existing conditions - anything that showed symptoms before enrollment or during a waiting period - are excluded by every insurer in the market. Some insurers make one honest exception: a curable condition can regain coverage after 6-12 symptom-free months, depending on the company (knee and ligament conditions are commonly carved out). Chronic conditions diagnosed before enrollment stay excluded for the pet's life.

The common Canadian menu is 70%, 80% or 90% reimbursement after a $0-$1,000 annual deductible, up to caps commonly between $5,000 and $15,000 (one major insurer offers no cap). The honest rule: set the deductible at the biggest bill you could comfortably absorb, and economize on the cap last - a low cap surfaces exactly when the bad year arrives.

Accident-only costs a fraction (about $251 a year for the average dog) and covers the broken-leg and swallowed-toy scenarios - but not the far more common illness claims: allergies, infections, cancer. If the full premium fits your budget, accident-and-illness is what the coverage debate is actually about; if not, accident-only still caps your worst single day.

Pre-existing condition determinations - insurers reviewing medical records at claim time and attributing a new problem to an old note. Protect yourself at enrollment: get a fresh vet exam, keep records, and where offered, ask the insurer for a written medical-history review upfront. If a denial seems wrong, escalate to your provincial regulator with the paper trail.
