Switching insurers to escape a premium increase after a claim rarely works the way drivers hope. Canadian auto and home insurers share access to centralized claims databases that store prior loss history, policy details, and in many provinces driving convictions. When you request a quote, underwriting systems query these records and match them to your identity using licence numbers, birth dates, and address history. A hail claim in Calgary or a water escape in Halifax can influence pricing three to six years later — sometimes longer depending on insurer policy and claim type.
Claims history is not punishment; it is statistical input. Insurers price expected future loss based on past loss. Knowing what follows you, for how long, and how to correct errors protects you when shopping and when renewing.
Where claims history lives
The primary industry database in Canada is Habitational Insurance Tracking System and Auto Insurance Tracking System — commonly referenced together as HITS/AITS through the Insurance Bureau of Canada infrastructure. Insurers report claims they pay or sometimes record, including at-fault and not-at-fault auto claims depending on reporting rules. Home claims — fire, theft, water — similarly attach to the property and the named insured.
Driving convictions flow through provincial motor vehicle registries and may appear on abstracts insurers request. Credit-based insurance scores in provinces that permit them add another layer separate from claims but queried during application.
Auto claims: fault, severity, and duration
- At-fault collisions: Typically affect premiums for three to six years; some insurers surcharge longer for major losses.
- Not-at-fault claims: Under direct compensation regimes in Ontario, Alberta, and other provinces, not-at-fault property damage claims may still appear and influence renewal with some insurers even when fault rules protect you legally.
- Comprehensive claims: Hail, theft, vandalism — often weighted less than at-fault collision but still visible.
- Glass claims: Some insurers treat separately; frequent glass claims may trigger comprehensive surcharges.
Claim forgiveness endorsements on renewal policies protect the first at-fault accident from premium increase with the same insurer — but do not erase the claim from industry databases. Switching insurers after forgiven claim may still surface the loss to competitors.
Home claims persistence
Home insurers report paid claims tied to both the policyholder and the property address. Selling a home does not erase the property's claim history — buyers' insurers may query prior losses at that address, affecting insurability or water coverage eligibility. As a buyer, ask for CLUE-equivalent disclosure through seller disclosure or insurance history reports where available.
Multiple water claims at one address often trigger declination for sewer backup or overland water endorsements until mitigation is documented.
Continuous coverage and lapses
Claims history intertwines with coverage continuity. Gaps — cancelling auto insurance while between vehicles, or failing to maintain tenant insurance during a move — signal higher risk to underwriters. Some insurers decline applicants with lapses exceeding 30 days unless special circumstances are documented.
When switching insurers, bind new coverage effective before or exactly when old coverage cancels. Same-day overlap is preferable to a gap.
Disputing inaccurate records
Errors happen: claims attributed to wrong drivers, duplicate entries, or claims closed without payment still showing as losses. Request your consumer report from the database administrator following IBC consumer access procedures. Dispute inaccuracies in writing with supporting documentation from the prior insurer. Corrections take weeks but prevent unfair surcharges.

Strategic decisions when you have claims
Not every repair warrants a claim. Compare deductible to repair cost; consider long-term premium impact. For minor comprehensive damage below deductible, paying out of pocket avoids a database entry. For liability exposure — anyone injured on your property — report regardless of immediate cost.
When shopping after a claim, work with brokers who place business with multiple insurers; each company weights history differently. High-risk residual markets exist in provinces with Facility Association or similar pools for drivers unable to obtain standard coverage.
Privacy and consent
Insurers obtain consent to collect and use personal information during application. Provincial privacy laws govern access and correction rights. You are entitled to know what information influenced an adverse underwriting decision in many jurisdictions.
Before your next renewal or switch
- Request your claims history report if premiums jumped unexpectedly.
- Align cancellation and effective dates to avoid coverage gaps.
- Ask prospective insurers how they treat not-at-fault and comprehensive claims.
- Document home mitigation after water claims to improve future eligibility.
- Keep copies of claim closure letters showing zero payment when disputes arise.
Claims history follows you because insurers share data designed to prevent fraud and align price with risk. Treat it as a financial footprint you manage — accurate, understood, and corrected when wrong — rather than something you outrun by changing logos on your policy documents.
