Factors That Affect Car Insurance Rates in Ontario: How Auto Insurance Is Calculated

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

There are several factors that affect your car insurance premiums. Insurers typically consider your driving record, where you live, the vehicle you drive, how you use your vehicle, your insurance history, and the coverage options you select. Insurance companies use these factors to assess risk and calculate your premium.

Car insurance premiums in Ontario are not determined randomly. Every insurer uses approved rating models and underwriting guidelines to evaluate the likelihood of future claims. Understanding these car insurance rating factors can help Ontario families make informed decisions when comparing coverage options.

This article provides general educational information about auto insurance in Ontario and is not intended as individual insurance advice. Coverage eligibility, underwriting rules, and premiums vary by insurer and individual circumstances. Speak with a licensed insurance professional regarding your specific situation.

What Factors Affect Car Insurance Rates in Ontario?

Several factors influence how car insurance rates are calculated in Ontario. Some factors are based on your driving habits and insurance history, while others relate to your vehicle, location, and provincial regulations.

What Are Car Insurance Rating Factors?

Car insurance rating factors are the characteristics insurers use to assess the likelihood and potential cost of future claims. These factors help insurance companies determine the level of risk associated with insuring a driver and establish an appropriate premium.

The Financial Services Regulatory Authority of Ontario (FSRA) regulates automobile insurance rates in Ontario and reviews rate filings submitted by insurers. Insurers must receive regulatory approval before implementing rate changes.

How Does Your Address Affect Car Insurance Rates?

Where you live is one of the most important factors that affect car insurance rates in Ontario.

Insurers analyze your postal code to assess local risk patterns, including:

• Collision frequency
• Vehicle theft rates
• Traffic congestion
• Claim severity trends
• Vandalism rates
• Weather-related claims

Drivers living in densely populated urban areas often experience higher premiums because they are exposed to greater traffic volumes and increased claim frequency.

Why Do Urban Drivers Often Pay More?

Large urban centres generally have:

• More vehicles on the road
• Greater accident frequency
• Higher repair and labour costs
• Increased vehicle theft activity

Comparing auto theft rates and populations in Toronto and Ottawa, the Toronto Police Service reported a known total of 7,363 auto theft incidents in 2025 and a total population of over 3 million people according to the City of Toronto’s Toronto at a Glance page. In contrast, the Ottawa Police Service reported only 1,400 incidents the same year with a total population of around 1 million according to the City of Ottawa’s statistics information. 

These numbers reinforce why insurance premiums can be higher in more populated areas. Moving to a different neighbourhood, city, or province can result in a change to your premium because insurers reassess the risks associated with your new location.

Does Your Driving Record Affect Car Insurance Premiums?

Yes. Your driving record is one of the most significant factors insurers consider.

A strong driving history demonstrates responsible driving behaviour and may result in more favourable premiums, while accidents and convictions can increase insurance costs.

Which Driving History Factors Matter Most?

Insurers commonly review:

• Years of driving experience
• Traffic convictions
• At-fault accidents
• Licence suspensions
• Previous cancellations for non-payment
• Claims history

Drivers with more years of licensed driving experience often pay lower premiums because they have established a longer driving history. To learn more about how important your driver’s history is, consider reading our blog on driver’s abstracts and why they are important.

How Do Traffic Tickets Affect Insurance Rates?

Traffic convictions may influence your premium depending on:

• The severity of the offence
• The number of convictions
• How recently the conviction occurred

Examples include:

• Speeding tickets
• Careless driving convictions
• Distracted driving convictions
• Failure to obey traffic signs

Maintaining safe driving habits, obeying posted speed limits, and avoiding distractions can help preserve a positive insurance record.

How Does Insurance History Affect Your Premium?

Insurance companies also review your prior insurance history when calculating premiums.

Factors that may be considered include:

• Continuous insurance coverage
• Previous claims activity
• Gaps in coverage
• Prior policy cancellations
• Previous use of accident forgiveness

A claims-free history may demonstrate lower risk over time.

Can Claims History Increase Insurance Costs?

Yes. Frequent claims, particularly at-fault claims, may influence future premiums.

However, claim frequency is only one consideration. Insurers also evaluate claim severity, timing, and overall driving history.

Some insurers offer accident forgiveness endorsements that may protect eligible drivers from premium increases following their first at-fault accident. Eligibility requirements vary by insurer.

What Role Does the Vehicle You Drive Play?

According to the Insurance Bureau of Canada’s (IBC) guide on how auto rates are set, the type of vehicle you choose can significantly affect your insurance costs.

The guide notes that insurers assess numerous vehicle characteristics, including:

• Make and model
• Vehicle age
• Repair costs
• Replacement value
• Safety ratings
• Theft frequency
• Availability of replacement parts

Which Vehicles Cost More to Insure?

Vehicles that may attract higher premiums include:

• Luxury vehicles
• Sports cars
• High-performance vehicles
• Frequently stolen models
• Vehicles with expensive repair parts

Conversely, vehicles equipped with advanced safety technology and anti-theft features may qualify for lower premiums.

How Do Safety Features Affect Insurance?

Safety technologies can reduce the likelihood or severity of collisions.

Examples include:

• Automatic emergency braking
• Blind-spot monitoring
• Lane departure warning systems
• Electronic stability control
• Anti-lock braking systems

According to the Insurance Institute for Highway Safety’s article on crash avoidance features, front crash prevention systems can substantially reduce certain types of collisions, which may positively influence insurance risk assessments. However, the same article also notes that these systems can increase repair costs as well.

Before purchasing a vehicle, especially if you are unsure of how much insurance for the vehicle may be, consider requesting a quote to speak with one of our licenced BIG brokers.

Does Annual Mileage Affect Car Insurance Rates?

Yes. Annual mileage is an important car insurance rating factor in Ontario. Generally, the more kilometres driven annually, the greater the exposure to potential accidents. To learn more about the importance of annual mileage, you can read our blog about it.

Regarding annual mileage, insurers commonly ask:

• How many kilometres you drive annually
• Whether you commute to work or school
• Whether the vehicle is used for business purposes
• How often the vehicle is driven

Drivers with shorter commutes or lower annual mileage may present lower exposure to risk, therefore possibly lower their insurance premium.

What Is Usage-Based Insurance (UBI)?

As explained in an article regarding UBI guidance by the Financial Services Regulatory Authority of Ontario (FSRA), usage-based insurance (UBI) programs use telematics technology to monitor driving habits.

Programs may track factors such as:

• Distance driven
• Time of day driven
• Braking patterns
• Acceleration habits

Ontario drivers interested in reducing unnecessary driving exposure may also consider carpooling, public transit, cycling, or remote work arrangements where practical. For families with questions, consider reviewing our helpful online resources on auto insurance to gain a better and more complete understanding of what BIG can do for you.

Do Age and Gender Affect Car Insurance Rates in Ontario?

Yes. Certain demographic characteristics may affect premiums because insurers rely on long-term actuarial data when assessing risk.

Why Are Younger Drivers Often Charged More?

Newly licensed drivers and younger motorists generally have less driving experience and are, therefore, typically a higher risk client. This point is reinforced in the Canadian Motor Vehicle Traffic Collision Statistics report by Transport Canada, which states that drivers between the ages of 16 and 24 accounted for over 22 thousand collisions in 2023, over 18% of the total number that year.

As drivers gain more road experience and maintain clean driving records, they are viewed as a lower-risk client. This often contributes to a decrease in insurance premium costs. 

Do Senior Drivers Pay More for Insurance?

Many senior drivers continue to qualify for competitive premiums, particularly when maintaining strong driving records. The Financial Services Regulatory Authority of Ontario (FSRA) also states in their guide on how to save on car insurance that seniors can be eligible for certain discounts, such as the retiree discount.

It is also important to remember that premiums may change as driving patterns, claim frequency, or annual mileage change over time. Ontario families may wish to review our blog on car insurance for senior citizens for a more complete explanation and deeper understanding of the topic.

How Does Coverage Selection Influence Your Premium?

The coverage options you select directly affect your premium.

Ontario drivers are required to carry mandatory automobile insurance coverage, including:

• Third-party liability coverage
• Statutory accident benefits coverage
• Direct Compensation–Property Damage (subject to current provincial rules and reforms)
• Uninsured automobile coverage

Ontario's minimum mandatory third-party liability limit is $200,000, although many drivers choose higher limits for additional protection.

Which Optional Coverages Increase Premiums?

Optional coverages may include:

• Collision coverage
• Comprehensive coverage
• Specified perils coverage
• All perils coverage
• Accident forgiveness
• Rental vehicle endorsements

Adding additional protection typically increases premiums because broader coverage transfers more financial risk to the insurer.

However, optional coverages may provide valuable protection depending on your vehicle, finances, and personal circumstances.

Reviewing your policy annually with a licensed BIG broker by requesting a quote can help ensure your coverage continues to align with your needs.

Can You Lower Your Car Insurance Premium in Ontario?

Many factors affecting car insurance rates are outside a driver's control, but several actions may help keep costs manageable.

Ontario drivers can consider:

• Maintaining a clean driving record.
• Comparing insurance options regularly.
• Choosing vehicles with favourable insurance characteristics.
• Updating annual mileage information when driving habits change.
• Asking about available discounts and telematics programs.
• Reviewing coverage needs periodically.
