Excess Liability
By LiabilityGap EditorialUpdated 2 min read
The short answer
Excess liability insurance adds an extra layer of coverage — commonly $1 million to $5 million, sometimes more — on top of the liability limits of your underlying home, auto, or watercraft policies. It pays only after an underlying policy has paid out its full limit, and most excess policies are follow-form, meaning they raise the ceiling without widening what's covered.
Excess liability insurance adds an extra layer of coverage — commonly $1 million to $5 million, sometimes more — on top of the liability limits of your underlying home, auto, or watercraft policies. It doesn't replace those policies; it sits above them and pays only after an underlying policy has paid out its full limit. Most excess policies are follow-form, meaning they adopt the same terms, conditions, and exclusions as the policy beneath them — they raise the ceiling without widening the room.
Here's the part that trips people up: in Canada, "excess liability" and "umbrella policy" are used almost interchangeably, and most personal umbrella policies sold by Canadian insurers are, in substance, excess policies. A true umbrella can respond to some claims the underlying policies exclude (subject to a self-insured retention); a pure excess policy never does. Ask your broker which one you're actually being offered — the wording matters more than the name.
Why it matters to you#
The default liability limit on most Canadian home and auto policies is $1 million, while serious injury awards in Canadian courts routinely exceed that — the largest reported motor vehicle awards run past $18 million. Excess liability is the cheapest way to close that gap: one layer, priced at roughly $200–$300 per year for the first $1 million and about $50–$75 per year for each additional million (estimates, not quotes). Because the excess insurer's money is at risk after the underlying limit exhausts, these policies also commonly continue funding your legal defence once your base insurer's duty to defend ends.
In practice#
- A court awards $2.4 million after a serious car crash. Your auto policy pays its $1 million limit; your $2 million excess policy pays the remaining $1.4 million. Without it, that $1.4 million is a personal debt.
- One excess layer can sit over several policies at once — auto, home, cottage, boat — so a single purchase raises every limit that matters.
- Because most excess policies follow form, a claim your auto policy excludes is usually excluded from the excess layer too.
Frequently asked questions
What is excess liability insurance?
Excess liability insurance adds an extra layer of coverage — commonly $1 million to $5 million — on top of the liability limits of your underlying home, auto, or watercraft policies. It pays only after an underlying policy has paid out its full limit.
What is the difference between excess liability and umbrella insurance?
A pure excess policy follows the terms of your underlying policies and only adds a higher limit. A true umbrella can also cover some claims your underlying policies exclude, usually subject to a self-insured retention. In Canada the terms are often used interchangeably, and most personal 'umbrella' policies sold here work like excess policies.
How much does excess liability insurance cost in Canada?
Typically about $200 to $300 per year for the first $1 million of coverage, and roughly $50 to $75 per year for each additional $1 million. These are estimates based on typical Canadian broker pricing, not quotes.
