Difference Between Collision and Comprehensive Auto Insurance in Canada

Updated

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

CollisionComprehensive
What triggers coverageYour vehicle hits something or is hitNon-collision damage to your vehicle
ExamplesRear-end accident, parking lot scrape, hitting a poleTheft, hail, fire, deer strike, flooding, vandalism
Fault requiredNo — pays regardless of faultNo — pays regardless of fault
Required by lawNoNo
Required by lendersYes, if vehicle is financed/leasedYes, if vehicle is financed/leased
Typically more expensiveYesNo (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

  1. Accident occurs → report to insurer
  2. Adjuster assesses damage; repair estimate prepared
  3. You pay your deductible first
  4. Insurer pays the balance of repair costs, up to the vehicle’s Actual Cash Value (ACV)
  5. If repair costs exceed ACV, vehicle is declared a total loss and you receive ACV minus deductible
  6. 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:

ProvinceInsurerNotes
BCICBC (mandatory basic; private for optional)ICBC provides collision and comprehensive as optional extensions
ManitobaMPI (Autopac)Collision and comprehensive included in most standard plans
SaskatchewanSGICollision/comprehensive add-ons available through SGI or private
QuebecMixedSAAQ covers bodily injury; property damage is private market
All othersPrivate marketCompetitive 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

FactorEffect on collision premiumEffect on comprehensive premium
Vehicle valueHigher value = higher premiumHigher value = higher premium
Deductible amountHigher deductible = lower premiumHigher deductible = lower premium
Your driving recordMajor factorMinor factor
Location (city vs. rural)Higher city = higher collisionHigher theft risk areas = higher comp
Vehicle type (truck, luxury, sports)VariesTheft-prone models = higher comp
At-fault claims historyMajor factorMinor factor
Parking (garage vs. street)Minor factorMajor 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
