Liability Car Insurance in Ontario: What Ontario Drivers Need to Know

Reviewed by Michelle Bragg, VP Personal Lines, RIBO Licensed | Last Reviewed: June 2026

Liability insurance is the portion of your auto insurance policy that helps pay for injuries, deaths, property damage, and legal costs when you are legally responsible for causing an accident. It protects your financial assets if another person suffers a loss because of your actions behind the wheel.

In Ontario, third-party liability coverage is a mandatory part of every automobile insurance policy. Drivers cannot legally operate a vehicle without at least carrying the minimum liability coverage required under Ontario law.

What Is Liability Car Insurance?

Liability car insurance is coverage that protects you when you are found legally responsible for causing injury to another person or damage to someone else's property while operating your vehicle.

Rather than paying compensation directly from your own savings, your insurer may respond to eligible claims up to the policy's liability limit.

What Does Liability Insurance Cover?

Liability coverage generally includes:

• Injuries suffered by other drivers, passengers, cyclists, or pedestrians
• Damage to another person's vehicle
• Damage to buildings, fences, signs, or other property
• Legal defence costs if a lawsuit arises from a covered incident
• Settlement payments and court-awarded damages up to policy limits

What Is Third-Party Liability Insurance in Ontario?

Third-party liability insurance refers to protection for damages suffered by other people (the "third party") when you are responsible for an accident.

For example:

• You rear-end another vehicle and the occupants are injured.
• You accidentally strike a fence or storefront.
• A pedestrian is injured because of an at-fault collision.

In these situations, your third-party liability coverage may help cover eligible damages and legal expenses.

What Is the Minimum Car Insurance Required for Ontario Auto Insurance Coverage?

Third-party liability coverage is one of the mandatory policies included in Ontario's mandatory auto insurance, which includes:

• Third-party liability coverage
• Statutory accident benefits
• Direct Compensation–Property Damage (where applicable)
• Uninsured automobile coverage

The Financial Services Regulatory Authority of Ontario (FSRA), in their What is in a standard auto insurance policy article, states that Ontario drivers must carry at least $200,000 in third-party liability coverage. Most insurers and insurance professionals recommend significantly higher limits because serious injury claims can exceed the minimum requirement, leading most Ontario drivers to choose limits of $1 million or $2 million for additional protection.

Why Is Liability Coverage So Important?

Liability claims can become expensive very quickly.

Medical treatment, rehabilitation expenses, income replacement claims, legal fees, and property damage costs can collectively result in substantial settlements.

According to Bergeron Clifford Injury Lawyers’ blog titled, How Much Is the Average Personal Injury Claim Worth in Ontario, serious and severe injury claims can add up to large sums ranging from $50,000 to $250,000 depending on various factors including the type and severity of the injury. Serious collisions can create financial obligations that extend well beyond vehicle repairs.

In other words, liability car insurance protects Ontario drivers from the financial consequences of causing injury or property damage to others. It helps pay eligible compensation, legal defence costs, and court-awarded damages up to the policy limit.

Considering the over 11 million licensed drivers in Ontario, according to the Preliminary 2024 Ontario Road Safety Annual Report released by the Ministry of Transportation of Ontario (MTO), and the rising costs of claims, protecting your financial assets is more important now than ever before.

What Does Liability Insurance Cover for Car Insurance in Ontario?

Coverage for Bodily Injury

If another person is injured in an accident you caused, liability insurance may help cover:

• Medical expenses
• Rehabilitation treatment
• Income replacement claims
• Long-term care expenses
• Funeral expenses in fatal accidents
• Legal costs associated with injury claims

Coverage for Property Damage

If another person's property is damaged because of an accident you caused, liability insurance may help pay for:

• Vehicle repairs
• Building repairs
• Fence replacement
• Damage to municipal infrastructure
• Personal property losses
• Associated legal expenses

Coverage for Legal Defence Costs

Many drivers overlook the legal component of liability coverage.

If a lawsuit is filed against you following an accident, your insurer may provide legal representation and cover eligible defence costs under the terms of the policy.

What Does Liability Insurance Not Cover?

Liability coverage protects other people when you are at fault. It does not typically pay for your own vehicle damage or personal losses.

Common exclusions include:

• Damage to your own vehicle
• Theft of your vehicle
• Vandalism
• Hail, wind, or falling objects
• Mechanical breakdowns
• Wear and tear
• Certain intentional acts
• Damage covered under collision or comprehensive coverage

Liability insurance is designed to protect other people from losses caused by an at-fault driver. Coverage for your own vehicle generally requires additional protections such as collision coverage or comprehensive coverage.

How Much Liability Coverage Should Ontario Families Carry?

Although Ontario requires a minimum of $200,000 in liability coverage, many insurance professionals consider this amount insufficient for modern claim costs.

Serious injury claims may involve:

• Hospitalization
• Rehabilitation programs
• Long-term disability support
• Loss of future income
• Legal proceedings

Because of these factors, many Ontario drivers select limits of $1 million or $2 million. Higher limits often provide significantly more protection relative to the increase in premium.

Why Do Many Drivers Choose $2 Million?

A $2 million liability limit can provide additional financial protection against large claims involving multiple injured parties or significant lawsuits.

The appropriate amount depends on your financial situation, driving habits, household assets, and risk tolerance.

What Factors Affect Liability Car Insurance Costs in Ontario?

Several variables influence the overall cost of your automobile insurance.

Driver Characteristics

Insurers may consider:

• Age
• Driving experience
• Licensing history
• Claims history
• Conviction history

Vehicle Characteristics

Insurance costs may also be influenced by:

• Vehicle make and model
• Repair costs
• Theft rates
• Safety features
• Vehicle usage

Geographic Location

Insurance premiums often vary across Ontario because of:

• Population density
• Traffic volume
• Historical claims experience
• Vehicle theft trends

Coverage Choices

Your premium may be affected by:

• Liability limits selected
• Deductibles
• Optional coverages
• Policy endorsements

What Is Liability-Only Insurance?

Liability-only insurance refers to a policy that includes required liability protection but does not include optional physical damage coverages such as collision or comprehensive insurance.

When Might Liability-Only Insurance Make Sense?

Some drivers consider liability-only insurance when:

• The vehicle has relatively low market value
• Replacement costs are manageable
• The owner wishes to reduce insurance expenses

Every driver's situation is different, so reviewing coverage options carefully is important.

What Are the Advantages?

Potential benefits include:

• Lower premiums
• Compliance with legal insurance requirements
• Simpler policy structure

What Are the Limitations?

Potential limitations include:

• No coverage for damage to your vehicle from collisions
• No protection for theft or vandalism
• Greater out-of-pocket costs after certain losses

How Does Liability Coverage Compare to Other Auto Insurance Coverages?

Below is a simple table comparing the basic coverages that an auto insurance policy might include.

Coverage Type	What It Generally Covers
Third-Party Liability	Injuries and property damage you cause to others
Collision Coverage	Damage to your vehicle following a collision
Comprehensive Coverage	Theft, vandalism, weather-related losses, and other non-collision events
Accident Benefits	Medical and rehabilitation benefits for insured persons
Uninsured Automobile Coverage	Protection involving uninsured or unidentified drivers

Remember that Ontario auto insurance coverage includes several mandatory components such as third-party liability insurance, accident benefits, uninsured automobile coverage, and direct compensation property damage (DCPD). These coverages work together to protect drivers financially in different accident scenarios.

What Happens If Your Liability Limit Is Exceeded?

If damages exceed your policy's liability limit, you may become personally responsible for amounts above the coverage limit.

For example, if your liability limit was $200,000 and court-awarded damages amounted to $750,000, you would become responsible for paying the difference of $550,000. This is one reason many Ontario drivers choose limits above the provincial minimum.

What Should Ontario Families Consider When Choosing Liability Coverage?

When reviewing liability limits, consider:

• Household assets
• Frequency of driving
• Daily commute distance
• Presence of young drivers in the household
• Potential legal exposure
• Overall financial goals

The right coverage amount depends on individual circumstances and risk tolerance.
