What is an insurance binder?

When you buy an insurance policy through a broker in Toronto, the full policy document may take days or weeks to generate and deliver. A binder bridges that gap by providing immediate, temporary proof that you are insured. It is usually issued by the broker or the insurer and confirms the essential terms of coverage: the type of insurance, the covered parties, the coverage limits, the premium amount, and the effective dates.

A binder is binding on the insurer unless it expressly states otherwise. This means that if a loss occurs during the binder period, the insurer is obligated to pay the claim according to the binder's terms, provided those terms match the final policy. The binder remains valid until the formal policy is issued and delivered, or until a specific expiration date written on the binder itself, whichever comes first.

Binders are common in home, auto, business liability, and commercial property insurance. They protect both the insured and the broker by establishing that coverage exists from the moment you apply, not from the moment you receive the printed policy weeks later. If you need to file a claim before your official policy arrives, the binder serves as proof that you were covered at the time of loss. Once the formal policy is in hand, the binder is superseded and no longer needed.
