When you buy auto insurance in Canada, the mandatory portion (liability and accident benefits) covers damage you do to others. Collision and comprehensive are the coverages that protect your own vehicle — and understanding the difference tells you when each applies.
The essential difference
| Collision | Comprehensive | |
|---|---|---|
| What triggers coverage | Your vehicle hits something or is hit | Non-collision damage to your vehicle |
| Examples | Rear-end accident, parking lot scrape, hitting a pole | Theft, hail, fire, deer strike, flooding, vandalism |
| Fault required | No — pays regardless of fault | No — pays regardless of fault |
| Required by law | No | No |
| Required by lenders | Yes, if vehicle is financed/leased | Yes, if vehicle is financed/leased |
| Typically more expensive | Yes | No (usually cheaper than collision) |
| Common deductibles | $500–$2,000 | $250–$1,000 |
Collision coverage: what it covers in detail
Collision pays for damage to your own vehicle resulting from:
✔ Your vehicle hitting another vehicle (regardless of fault)
✔ Another vehicle hitting your parked car
✔ Your vehicle hitting a stationary object: pole, fence, wall, guardrail, tree
✔ Your vehicle rolling over
✔ Your vehicle falling into a pothole (may depend on insurer)
✔ Hit and run, where the at-fault driver cannot be identified
Does NOT cover:
✗ Damage from theft
✗ Damage from weather (hail, flood, ice)
✗ Hitting an animal
✗ Vandalism
✗ Fire
✗ Glass chip repair (no collision involved)
How a collision claim works
- Accident occurs → report to insurer
- Adjuster assesses damage; repair estimate prepared
- You pay your deductible first
- Insurer pays the balance of repair costs, up to the vehicle’s Actual Cash Value (ACV)
- If repair costs exceed ACV, vehicle is declared a total loss and you receive ACV minus deductible
- If you are not at fault: adjuster may pursue the other driver’s insurer for reimbursement; your insurer may waive the deductible if the other party is fully at fault
Comprehensive coverage: what it covers in detail
Comprehensive (also called “all perils other than collision”) pays for non-collision damage to your vehicle:
✔ Theft — vehicle stolen (and recovered damaged or not recovered at all)
✔ Fire — engine fire, arson, fire spreading from adjacent vehicle
✔ Hail and windstorm — dents, broken glass from a hailstorm
✔ Flooding — rising water entering the vehicle (from weather events, not standing water from poor drainage in most policies)
✔ Falling objects — tree branch, ice from a bridge, falling signage
✔ Animal strike — hitting a deer, moose, dog, or other animal (a common claim in rural Canada)
✔ Vandalism — keying, slashing tires, smashed windows
✔ Windshield damage — chips and cracks (may be covered with no or reduced deductible on many policies)
✔ Earthquake and civil commotion — depends on policy
Does NOT cover:
✗ Collision damage (a deer running into your stationary car = comprehensive; you driving into a deer = also comprehensive; you hitting a curb to avoid a deer = collision)
✗ Mechanical breakdown
✗ Wear and tear
✗ Personal belongings stolen from inside the vehicle (covered under home/tenant’s insurance, not auto)
The deer question (common confusion)
In Canada, striking a deer or other animal is claimed under comprehensive, not collision — even though it happens while you are driving. The distinction is that “collision” refers to striking another vehicle or a stationary object; animals are considered a “non-collision loss” and fall under comprehensive. This matters for deductible selection: many people set their comprehensive deductible lower ($250–$500) than their collision deductible ($1,000–$2,000) because animal strikes are frequent in many Canadian areas and the damage is often significant.
Canada-specific auto insurance context
Auto insurance is provincially regulated in Canada. Some provinces have government-run insurers:
| Province | Insurer | Notes |
|---|---|---|
| BC | ICBC (mandatory basic; private for optional) | ICBC provides collision and comprehensive as optional extensions |
| Manitoba | MPI (Autopac) | Collision and comprehensive included in most standard plans |
| Saskatchewan | SGI | Collision/comprehensive add-ons available through SGI or private |
| Quebec | Mixed | SAAQ covers bodily injury; property damage is private market |
| All others | Private market | Competitive market; shop annually |
In provinces with public auto insurance, collision and comprehensive may work differently (bundled, government-regulated deductibles) — check your policy.
Premium comparison: what affects your collision vs. comprehensive rates
| Factor | Effect on collision premium | Effect on comprehensive premium |
|---|---|---|
| Vehicle value | Higher value = higher premium | Higher value = higher premium |
| Deductible amount | Higher deductible = lower premium | Higher deductible = lower premium |
| Your driving record | Major factor | Minor factor |
| Location (city vs. rural) | Higher city = higher collision | Higher theft risk areas = higher comp |
| Vehicle type (truck, luxury, sports) | Varies | Theft-prone models = higher comp |
| At-fault claims history | Major factor | Minor factor |
| Parking (garage vs. street) | Minor factor | Major factor — street parking = higher theft risk |
Comprehensive is almost always cheaper than collision because most non-collision events are less frequent and insurers can spread the risk widely (hail, for example, affects many cars at once but is a regionally priced risk).
Do you need collision and comprehensive? (Decision framework)
Rule of thumb: 10% test
Calculate: annual (collision + comprehensive) premium ÷ current vehicle ACV × 100
- If this ratio is < 10%: coverage is likely financially worthwhile
- If this ratio is > 10%: consider whether the coverage still makes sense
Example:
- Vehicle ACV: $12,000
- Annual collision + comprehensive premium: $900
- Ratio: $900 / $12,000 = 7.5% → worth keeping
Example:
- Vehicle ACV: $4,500
- Annual collision + comprehensive premium: $750
- Ratio: $750 / $4,500 = 16.7% → consider dropping; you would break even after 6 years of no claims
Lender requirements
If your vehicle is financed or leased, you must maintain collision and comprehensive regardless of the vehicle’s age or value. The lender has a financial interest in the physical asset.
When to always keep comprehensive alone
Comprehensive is inexpensive (often $100–$250/year). Even for older vehicles, keeping comprehensive makes sense because it covers theft, which is not necessarily correlated with vehicle age. A 2010 Honda Civic is still a theft target in parts of Canada (high parts demand). Drop collision before dropping comprehensive on older vehicles.
Claim history and premiums
Filing either a collision or comprehensive claim typically results in a premium increase at renewal, unless you have claims protection (accident forgiveness) added to your policy. Some insurers exclude comprehensive claims (particularly glass repair and small claims) from affecting your rate — check your policy. In general:
- A single at-fault collision claim can raise your premium by 20–40% for 3–6 years
- A comprehensive claim (theft, hail) typically has less premium impact than an at-fault collision
- Multiple claims within a few years can make you a higher-risk account renewing at elevated rates
