How much auto insurance do you need in Ontario?

Every Ontario auto policy is written on the same form — the Ontario Automobile Policy, or OAP 1.² What changes between drivers is not the wording but the limits: how much the insurer will pay before the money runs out and the rest becomes yours.

Most people never choose their liability limit. It is set once, at the first policy, and then carried forward through every renewal for twenty years without anyone looking at it again.

Ontario’s legal minimum

The Insurance Act requires every driver to carry at least $200,000 in third-party liability.¹ That number was set in 1990 and has never been raised. Adjusted for inflation it would be well over $400,000 today.

Third-party liability is the part of the policy that pays other people when you are at fault — their injuries, their vehicle, their lost income. It does not pay for your own car; that is collision coverage, which is separate and priced separately.

Standard wording. OAP 1 is a standard form. No carrier can change what the coverage means — only what it costs and what endorsements sit on top. This is why comparing carriers is a comparison of price and service, not of fine print.

Why the minimum is not enough

A single serious injury claim in Ontario routinely settles above $1 million once future care costs and lost earnings are counted. If a judgment exceeds your limit, the difference is collected from you personally: wages, savings, and in some circumstances the equity in your home. The exposure is largest in households with a newly licensed driver, where the probability side of the equation moves as well as the cost side.

This is the single most consequential number on your policy, and most drivers have never been asked about it.

What each limit actually costs

The pattern holds across carriers: the frequency of catastrophic claims is low even though their cost is high, so the insurer charges very little for the extra headroom. Sample figures — your own will differ by postal code, vehicle and driving record.³

Choosing your liability limit

Most Ontario brokers place personal auto at $1 million or $2 million. Two endorsements are worth knowing by name:

• OPCF 44R — family protection. Pays your own family if the at-fault driver is uninsured or underinsured. Roughly $40 a year and, in our experience, the endorsement clients are most grateful for after a claim.
• OPCF 43 — waiver of depreciation. Keeps a new vehicle’s payout at purchase price rather than market value for the first two years.

44R is the one people miss. Your own limit protects other people from you; 44R protects you from someone else carrying the 1990 minimum.

The extra premium is small enough that most households can fund it from a single discount: bundling home and auto usually saves more in a year than a $2 million limit costs.
