Group 1 auto insurance is the lowest risk category that insurers use to set rates, and it typically applies to safe, common vehicles with strong safety records and low theft rates

When you buy car insurance, the insurer assigns your vehicle to a group based on how much it costs to repair, how often it gets stolen, and how well it performs in crash tests. Group 1 is the safest and cheapest category — vehicles here have the lowest claims history, highest safety ratings, and lowest theft rates. A Honda Civic, Toyota Corolla, or Subaru Legacy might fall into Group 1, while a sports car or luxury sedan would be in a higher group and cost more to insure.

The group your car is in directly affects your insurance premium. A Group 1 vehicle will cost less to insure than the same coverage on a Group 5 or Group 10 car, all else equal. This is one reason why choosing a vehicle with a good safety record and low repair costs can save you hundreds of dollars a year on insurance.

Key Takeaways

  • Group 1 vehicles have the lowest insurance rates because they are safe, affordable to repair, and rarely stolen.
  • Your vehicle's group is determined by the Insurance Bureau of Canada (IBC) based on repair costs, safety ratings, and theft data.
  • The same model year and trim level can fall into different groups depending on engine size, transmission type, and safety features.
  • Switching to a Group 1 vehicle can lower your insurance costs significantly compared to higher-group cars.
  • You can check your vehicle's group rating before you buy by looking it up on the IBC website or asking your insurer.

How the Insurance Bureau of Canada assigns vehicle groups

The Insurance Bureau of Canada (IBC) maintains the official vehicle group ratings used by most insurers across the country. They assign each vehicle model and variant to a group from 1 to 50 based on three main factors: the cost to repair the vehicle after a collision, how often it is stolen or broken into, and its performance in crash tests and safety ratings.

The IBC updates these ratings regularly as new models arrive and claims data changes. A vehicle might move to a higher group if repair costs rise or theft rates increase in a particular region. Conversely, a model with improving safety features or declining theft rates might move down. This means a 2022 model of a car might be in a different group than a 2024 model of the same car.

Insurers are not required to use the IBC groups — some use their own internal ratings — but most major Canadian insurers follow the IBC system closely. A few insurers may place a vehicle in a slightly different group, so it is worth checking with your specific insurer if the group matters to your decision.

What makes a vehicle fall into Group 1

Group 1 vehicles share several characteristics. They are typically compact or mid-size sedans and hatchbacks with four-cylinder engines, automatic or manual transmissions, and no high-performance upgrades. They have strong crash test ratings from the National Highway Traffic Safety Administration (NHTSA) or the Insurance Institute for Highway Safety (IIHS). They are also common models with readily available parts and straightforward repair procedures, which keeps repair costs down.

Theft rates matter too. A vehicle that is rarely stolen or broken into will stay in a lower group. Popular, common vehicles like the Honda Civic, Toyota Corolla, and Mazda3 tend to be in Group 1 or Group 2 because they are not high-theft targets and parts are inexpensive. Luxury vehicles, sports cars, and trucks with high-value components or high theft rates will be in much higher groups.

The specific trim level and engine size can move a vehicle between groups. A base Honda Civic with a 2.0-litre engine might be Group 1, while a Civic Si with a turbocharged engine and sport suspension could be Group 3 or higher. Always check the exact year, make, model, and trim before assuming a vehicle is Group 1.

How Group 1 status affects your insurance cost

Your vehicle's group is one of several factors that determine your insurance premium. Others include your age, driving record, location, coverage limits, and deductible. But the vehicle group is significant — moving from a Group 1 car to a Group 5 car can increase your annual premium by several hundred dollars, even if everything else stays the same.

Insurers use group ratings to predict the likelihood and cost of a claim. A Group 1 vehicle is statistically less likely to be in a serious accident, less likely to be stolen, and cheaper to repair if damaged. This lower risk translates to lower premiums. If you are shopping for a car and insurance cost is a concern, choosing a Group 1 or Group 2 vehicle will save you money over the life of ownership.

The savings compound over time. If a Group 1 vehicle costs $200 less per year to insure than a Group 5 vehicle, that is $2,000 over ten years — money that could go toward maintenance, fuel, or savings.

How to find your vehicle's group rating before you buy

The IBC maintains a searchable database on its website where you can look up any vehicle's group rating by year, make, model, and trim. This tool is free and takes about two minutes. You enter the vehicle details and the database returns the group number and a brief explanation of why that group was assigned.

You can also call your insurance company and ask them to look up the group for a specific vehicle you are considering. Many insurers will give you a rough estimate of the insurance cost for that vehicle over the phone, which can help you compare options before you commit to a purchase.

If you are buying a used car, the group rating is the same as it would be for a new model of that year, make, and trim. A 2019 Honda Civic in Group 1 will have the same group rating whether it has 30,000 miles or 100,000 miles on it. The group does not change based on the individual vehicle's condition or history — only the model and variant matter.

Group 1 vehicles and theft risk

Group 1 vehicles are generally not high-theft targets, which is one reason they stay in the lowest group. However, this does not mean they are never stolen. Popular models like the Honda Civic do see theft, especially older model years and certain trims that have valuable parts or weaker security systems.

If you own a Group 1 vehicle, basic theft prevention measures still matter: park in a garage or well-lit area, use a steering wheel lock or alarm system, and never leave the keys in the car or visible on the seat. Some insurers offer discounts for anti-theft devices, which can lower your premium further.

If your Group 1 vehicle is stolen, your comprehensive coverage will pay out the actual cash value of the car minus your deductible. The group rating does not affect how much you are paid — only the value of the vehicle and your coverage limits do.

Frequently Asked Questions

Can I move a higher-group vehicle into Group 1 by modifying it?

No. The vehicle's group is based on the factory specifications for that year, make, model, and trim. Modifications you make after purchase do not change the group rating. In fact, some modifications like engine upgrades or lowering kits might cause your insurer to charge you more, even though the official group stays the same.

Does my driving record affect what group my car is in?

No. The group is determined by the vehicle itself, not by who owns it or how they drive. Your driving record affects your personal insurance rate, but not the vehicle's group. A Group 1 car will be Group 1 whether you have a perfect record or a history of accidents.

If I buy a Group 1 car, will my insurance definitely be cheaper?

Probably, but not always. The vehicle group is one factor among many. Your age, location, coverage limits, and deductible also matter. A young driver in a high-theft area might pay more for a Group 1 car than an older driver in a rural area pays for a Group 3 car.

Do all insurers use the same group ratings?

Most Canadian insurers follow the IBC group ratings, but some use their own systems or adjust groups slightly based on their claims experience. It is worth asking your insurer which system they use and whether they have any vehicle-specific discounts that might explore to the car you are considering.

What is the difference between Group 1 and Group 2?

Group 2 vehicles are slightly higher risk than Group 1 — they may have higher repair costs, marginally higher theft rates, or slightly lower safety ratings. The difference in insurance cost between Group 1 and Group 2 is usually small, often $20 to $50 per year, but it depends on the specific vehicles and your insurer.
