Ontario law requires at least $200,000 in third-party liability coverage on every car insurance policy, but that is only the legal floor. Most drivers choose $1 million or $2 million, because a serious collision can create claims much larger than the minimum. The right limit depends on what you own, what you earn and how much risk you are comfortable carrying yourself.
Key takeaways
- The legal minimum liability limit in Ontario is $200,000.
- Most people choose $1 million or $2 million for better protection.
- If a claim exceeds your limit, you may have to pay the difference yourself.
- Moving to a higher limit often costs relatively little compared with the added protection, but quotes vary.
- Ask a broker for several limits side by side before you decide.

What liability coverage actually does
Third-party liability pays when you are legally responsible for injuring someone or damaging their property with your car. It covers the other person's costs, and it also helps pay for your legal defence if you are sued. "Third party" simply means someone other than you and your insurer.
It does not repair your own car. Collision and comprehensive coverage do that. It also does not pay your own injury costs, which are handled by accident benefits. If you want to see how all of these pieces fit together, read our guide to Ontario car insurance coverages explained.
Liability is one of three coverages that must be in every Ontario policy, together with statutory accident benefits and uninsured automobile coverage.
Why $200,000 is rarely enough
The legal minimum was set to make sure every driver has something in place. It was not designed to cover every real-world situation.
Think about what a serious collision can involve:
- Long-term medical and rehabilitation costs for an injured person
- Lost income for someone who can no longer work
- Damage to several vehicles, or to a building or fence
- Legal fees if the case goes to court
Costs like these can add up quickly. If a judgment is larger than your limit, the insurer pays up to the limit and the rest becomes your responsibility. That could affect your savings, your home equity, or your wages in the future. This is the main reason many people carry far more than the minimum.
Comparing $200,000, $1 million and $2 million
| Limit | Who often chooses it | Main trade-off |
|---|---|---|
| $200,000 | Drivers who want only the legal minimum | Lowest price, but the highest personal risk if a claim is large |
| $1 million | A common choice for many households | Strong protection for a modest increase in cost |
| $2 million | Homeowners, higher earners, business owners, or anyone with more to protect | The most protection, usually at a small extra cost over $1 million |
The exact price difference between these limits varies by insurer, driver and vehicle. We do not publish figures here because they change. Ask for them in a quote.
How to decide on your limit
There is no single answer, but a few questions point you in the right direction.
A useful exercise is to write down, on one page, what a lawsuit could reach: the equity in your home, your savings and investments, and a rough idea of what you earn in a year. Then compare that total with each limit. If the total is far larger than $200,000, the minimum leaves a wide gap. If it is smaller than $1 million, that limit may already cover most of what you could lose. This is not a calculation that gives a perfect answer, but it turns a vague worry into something you can discuss with your broker.
1. What do you have to protect?
People with a home, savings, investments or a steady high income have more to lose in a lawsuit. They often lean toward $2 million. If you have fewer assets, you still face a risk to your future earnings, so $1 million is a common starting point.
2. How and how much do you drive?
If you commute daily, drive highways or carry passengers regularly, you are exposed to more situations where something can go wrong. A higher limit is easier to justify.
3. Do you drive for work?
If your car is used for business, there may be extra rules and different coverage needs. Talk to your broker, and see our business insurance page for related options.
4. How much risk can you tolerate?
A higher limit is a way of transferring risk to the insurer. If a large claim would be a disaster for you, buying more protection may bring peace of mind.
The cost of going higher
A common surprise is that going from $1 million to $2 million often costs less than people expect, because the extra layer of coverage is used far less often than the first. The amount still varies by insurer and by driver, so the only reliable way to know is to ask for both quotes. Compare the extra yearly cost with the difference in protection, then decide what feels reasonable for your household.
Your driving record also plays a part in the overall premium. If you want to understand how claims affect your price, read about at-fault accidents and Ontario insurance rates.
Related coverage: protection from underinsured drivers
You can choose a high limit, but you cannot control the limit of the person who hits you. If an at-fault driver has too little liability insurance to pay for your injuries, you may be left short.
An endorsement called OPCF 44R, known as Family Protection, is designed for that situation. It tops up what you can recover when the at-fault driver's liability insurance is too low. It typically goes up to $1 million of your own limit. It also tends to be linked to your own liability limit, which is one more reason to think about the number you choose. Ask your broker how it works on your policy.
Before you act: what to ask your broker
- What is my current liability limit, and what are my options?
- What is the price of $1 million compared with $2 million for my situation?
- Does my policy include OPCF 44R, and does it fit my limit?
- If I use my car for work, is my coverage still appropriate?
- Do I need extra liability protection from another policy, such as a home policy?
- Will this limit also apply to other drivers listed on my policy?
Brokers in Ontario are licensed by RIBO, and the regulator, FSRA, publishes consumer information about car insurance. When you are ready to compare, you can request an auto quote. If you own a home, our home insurance page explains how personal liability under a home policy works separately from your car.
A simple example
Picture a commuter on a Toronto highway who changes lanes and clips another car. The crash pushes that car into a third vehicle, and one occupant needs months of treatment. Several people can now make claims against the same driver, and all of them draw on the same single liability limit. A higher limit gives more room for these combined claims. This is only an illustration, not a prediction, but it shows why one accident can involve more than one claim and why a limit that looked large on paper can be used up faster than expected.
Common mistakes to avoid
- Picking the minimum to save a little. The savings are often small compared with the possible exposure.
- Assuming the other driver will have enough insurance. That is not guaranteed.
- Never reviewing your limit. Your life changes. A new home, a new job or a growing family can change what you should protect.
- Not asking for several quotes. Prices for different limits can be closer than you think.
- Treating the limit as a per-person amount. The limit is generally what is available for the accident as a whole, so several injured people and damaged vehicles can share it. Ask your broker how it applies to your policy.
- Forgetting other drivers. If family members drive your car, their mistakes can also draw on the same limit, so think about everyone who uses the vehicle.
Bottom line
The $200,000 minimum keeps you legal, but it rarely keeps you safe. For most Ontario drivers, $1 million is a sensible starting point and $2 million is worth a serious look if you have more to protect. Ask your broker to quote each option side by side, think honestly about your assets and your risk tolerance, and choose the limit that lets you sleep well.
