What is third-party liability car insurance?
Third-party liability insurance (TPL) is an important part of your automobile policy. Even when you do everything you can to prevent damage or injury, crashes still happen, and accident claims often result in legal proceedings and lawsuits. According to the Insurance Bureau of Canada (IBC), third-party liability claims payouts accounted for 46.6% of all direct claims incurred.
Third-party liability provides financial protection if you are found responsible for an accident that results in property damage, repairs, personal injury, or death. It is mandatory on all Canadian automobile policies. When someone makes a claim against you, TPL takes effect, so you do not have to pay out of pocket for damages you are responsible for.
For example, suppose you rear-end another vehicle, injuring the driver and damaging their car. You would be at fault and a claim would be filed, and this is where TPL takes effect. It would cover the victim's property, repairs, medical costs, and even lost wages where applicable.
Third-party liability also exists under your home insurance, but that is a separate type of coverage that does not apply to your auto policy.
Third-party liability insurance: a quick summary
- Third-party liability insurance is mandatory and included in all car insurance policies.
- It protects you if you injure or cause damage to a third party while driving.
- We recommend carrying more than the minimum amount of third-party liability coverage.

What is covered by third-party liability insurance?
Your third-party liability covers the following:
- Repair costs for vehicles damaged in an accident you caused.
- Repair costs for any property you have damaged.
- Medical costs for anyone you have injured.
- Legal fees and lawsuits resulting from the accident.
- Damages awarded to the injured parties from a lawsuit.
Third-party liability does not cover the cost of injuries to yourself or damage to your own vehicle in an at-fault accident. Accident benefits and collision coverage are used for that. No-fault insurance laws do not protect you from injury lawsuits if you seriously injure a third party in a collision.
How does third-party liability car insurance work?
If you cause injury, death, or property damage, third-party liability insurance applies and will cover these types of car insurance claims up to your policy limit. Here are some examples:
- You back into your neighbour's fence.
- Your vehicle slides off the road in slippery conditions and damages a business advertising sign or a streetlight.
- You lose control of your vehicle and drive into the storefront of a local business.
- You hit a pedestrian or cyclist while driving and they sue you for damages.
- You cause an accident with another vehicle that results in a death, and the deceased motorist's family sues you.

Third-party liability insurance examples
Here are two examples that show the importance of third-party liability:
Example 1: property damage liability
John accidentally rear-ended another car at a traffic light, causing $2,500 in damage. His third-party liability insurance covered the cost of repairs for the other car, but it did not cover the damage to his own car.
Example 2: bodily injury liability
Sarah ran a red light and collided with Tom's car, causing a broken leg, $15,000 in medical expenses, and lost wages. Sarah's third-party liability car insurance covered Tom's expenses.
How much third-party liability insurance do I need?
All drivers in Canada must carry a minimum amount of third-party liability insurance on their auto policy. The compulsory amount is set at the provincial level; most provinces require a minimum of $200,000.
However, because of the cost of medical bills and lawsuits, increasing your limits is highly recommended. You can increase your coverage to $500,000, $1 million, or $2 million without a large increase to your premium.
Once a claim surpasses your limits, you are required to pay the remaining costs out of pocket, and a court judgment or settlement can be applied against your assets. Increasing your limits reduces the chance of this happening.

How much does third-party liability insurance cost?
Third-party liability is not a standalone policy. It is included as part of your mandatory coverage, along with accident benefits.
The cost of TPL depends on your limits and how much additional protection you add, such as collision, comprehensive, Direct Compensation Property Damage (DCPD), and other policy add-ons.
Other factors, such as the vehicle you drive, your location, and your driving history, will also affect your premium.
When should I increase my third-party liability limits?
Basic plans provide a minimal amount of coverage, and how you use your vehicle affects your potential risk. It is recommended you increase your limit if:
- You carpool or frequently drive with others in the vehicle.
- You drive your vehicle to work.
- You drive in the United States frequently.
- You drive in a high-traffic area.

Third-party liability insurance FAQs
In most cases, your current policy includes third-party liability for your rental car insurance. However, it may or may not cover collision or damage to the rental vehicle. Speak with your advisor for clarification.
In every accident, there are three parties. The driver is the first party, the insurance company is the second party, and the other driver or person who was injured or had property damaged is the third party.
If you were at fault for an accident and caused injury or property damage to a third party, your insurer reviews the costs to compensate them and offers a settlement. The third party can agree to the terms, seek legal advice, or file a lawsuit. It covers costs up to your policy limit.

Third-party liability is mandatory, so the real question is how much. The $200,000 minimum is rarely enough given today's medical and legal costs. Increasing your limit to $1 million or $2 million usually costs little and protects your assets if a claim goes higher.
