Key Takeaway

CTP (compulsory third-party) insurance is known as third-party liability coverage in Canada and is mandatory in every province and territory. It pays for bodily injury and property damage you cause to others in an at-fault accident. Minimum liability limits range from C$200,000 in most provinces to C$500,000 in Nova Scotia, but experts recommend carrying at least C$1 million to C$2 million in coverage.

What Is Third-Party Liability Coverage

In Canada, the coverage known as CTP in other countries is called third-party liability insurance. It protects you financially when you are legally responsible for injuring someone or damaging their property in a car accident. The term “third party” refers to anyone other than you (the first party) and your insurer (the second party), meaning other drivers, passengers, pedestrians, cyclists, or property owners (Insurance Bureau of Canada, 2026).

Every province and territory requires drivers to carry a minimum amount of third-party liability coverage before they can register a vehicle or legally drive. This requirement ensures that victims of at-fault accidents have a source of compensation for their injuries and losses.

What Third-Party Liability Covers

Third-party liability coverage pays for two main categories of damage when you are found at fault in an accident:

Bodily injury: Medical expenses, rehabilitation costs, lost wages, pain and suffering, and funeral expenses for anyone injured or killed in an accident you cause. This includes passengers in other vehicles, pedestrians, and cyclists.

Property damage: Repair or replacement costs for vehicles, buildings, fences, utility poles, and other property you damage in an at-fault accident.

Your insurer will also cover legal defence costs if you are sued as a result of the accident, up to your policy limit.

What It Does Not Cover

Third-party liability does NOT cover damage to your own vehicle or injuries to you and your passengers. For those, you need separate coverages:

  • Collision coverage pays for damage to your own vehicle in an at-fault accident.
  • Comprehensive coverage protects against theft, vandalism, weather, and other non-collision damage.
  • Accident benefits coverage (required in most provinces) pays for your medical expenses and lost income regardless of fault.

Minimum Requirements by Province

According to the Financial Consumer Agency of Canada (2026), minimum third-party liability limits vary by province and territory. Most provinces require C$200,000, while Nova Scotia mandates C$500,000. British Columbia, Saskatchewan, Manitoba, and Quebec operate public auto insurance systems with their own minimum requirements.

Insurance professionals strongly recommend purchasing at least C$1 million to C$2 million in third-party liability coverage. The cost difference between minimum coverage and C$1 million is often modest (typically C$50 to C$150 per year), but the financial protection gap is enormous. A serious multi-vehicle accident or catastrophic injury can easily exceed C$200,000 in damages.

Next Steps

Review your current auto insurance policy to confirm your third-party liability limit. If you carry only the provincial minimum, contact a licensed insurance broker or agent to get quotes for higher limits. Compare the premium difference and consider whether the additional protection fits your budget and risk profile.
