Commercial umbrella insurance: extra liability protection for Ottawa businesses
Part of the series: Business insurance in Ottawa →
One serious claim, like a crash involving a work vehicle or a customer injury, can go beyond the $1 million or $2 million limit on a typical small business policy. Commercial umbrella and excess liability insurance add another layer of protection on top.
How an umbrella policy works
An umbrella sits above your primary liability policies, usually commercial general liability, commercial auto liability and, if you have it, employer’s liability. When a covered claim uses up the primary limit, the umbrella pays the rest, up to its own limit.
Umbrella vs. excess liability
| Excess liability | Umbrella liability | |
|---|---|---|
| What it does | Adds limits on the same terms as the policy below it (“follows form”) | Adds limits, and may be broader than the policy below it in some situations |
| Claims the policy below doesn’t cover | Generally not covered | Some may be covered, after a self-insured retention (an amount you pay first) |
| Best for | Adding limits on top of one specific policy or layer | Adding limits over several policies at once, such as general liability and auto |
Policy wording varies a lot between insurers, so the label matters less than what the policy actually says.
Who should consider an umbrella in Ottawa
- Contractors bidding on work that requires $5 million, such as City of Ottawa road cut permits or large general contractor projects
- Businesses with vehicles or fleets, since auto accidents can lead to some of the largest liability claims
- Businesses with lots of public traffic, such as shops, restaurants, event venues and property owners
- Suppliers to federal departments, property managers or large companies that set high insurance limits in their contracts
What to check before you buy
- Required underlying limits. The umbrella insurer will require minimum limits on your general liability and auto policies, often $1 million or $2 million. If an underlying policy lapses or has a lower limit, you could have to pay the gap yourself.
- Whether your contract accepts it. Many contracts accept a combination of primary and umbrella limits to reach the total they require, but confirm with the contract holder before you rely on it.
- What’s excluded. Umbrellas usually don’t cover professional errors, damage to your own property, or anything excluded in both the umbrella and the underlying policy. For professional mistakes, see professional liability (E&O).
- Matching dates and insurers. Keep the umbrella and underlying policies on the same dates where possible, and tell your broker right away about any change to an underlying policy.
Because an umbrella only pays after the primary policy is used up, each extra million of coverage usually costs less than the first million. The price depends mainly on your industry, vehicles and claims history.

Common questions
Is an umbrella the same as raising my general liability limit?
The effect can be similar, but an umbrella can extend over several policies at once, such as general liability and commercial auto. Sometimes raising the primary limit is simpler or cheaper, so it’s worth comparing both.
Does an umbrella cover professional mistakes?
Usually not. Professional liability is typically excluded and needs its own policy.
How much umbrella coverage do I need?
It depends on your contracts, vehicles, public exposure and assets. For small businesses, umbrella limits often range from $1 million to $5 million or more. Start with the highest limit any of your contracts require.
Can my personal umbrella policy cover my business?
Usually not. Personal umbrella policies typically exclude business activities.
Check whether your limits are high enough
