Commercial Liability Insurance for Small Business
Commercial liability insurance for small business in Canada: what CGL covers, what it excludes, limits, and how to buy a policy. General information only.
Commercial liability insurance for small business — commonly sold as commercial general liability (CGL) — pays third-party claims of bodily injury, property damage, and related defence costs arising out of your operations in Canada. No federal law requires a sole proprietorship to carry it, but landlords, clients, and some licensing bodies often demand proof of coverage before signing a contract. This guide explains what a typical policy covers, what it leaves out, and how to buy coverage that fits your business today.
What Commercial General Liability Typically Covers
A CGL policy responds when someone outside your business claims your business caused them harm. Subject to the wording of your policy, standard coverage usually includes third-party bodily injury and property damage, plus the cost of defending a covered claim. Typical elements include:
- Bodily injury — a customer slips in your workspace, or a passerby is injured by equipment you left on a job site.
- Property damage — you damage a client's premises, their equipment, or a neighbouring property.
- Personal and advertising injury — claims such as libel, slander, or wrongful detention arising from your premises or advertising.
- Products and completed operations — harm caused by a product you sold or work you finished, within the policy's time limits.
- Medical payments — minor injury expenses paid without a finding of fault, where the policy includes this.
- Legal defence costs — which may sit inside or outside your limit, depending on the policy.
Coverage is written for injury or damage to others, not to you. Your own tools, inventory, and premises are a separate conversation, covered by general liability insurance wording that differs from policy to policy.
What Commercial Liability Insurance Usually Excludes
Gaps matter as much as coverage. Common exclusions include damage to your own property, injuries to your own employees, professional errors, and intentional or criminal acts. The table below shows which policy typically responds.
| Situation | Policy that usually responds |
|---|---|
| A client sues over bad advice or a design error | Professional liability (errors and omissions) |
| Fire damages your own office contents | Commercial property insurance |
| An employee is hurt on the job | Provincial workers' compensation coverage |
| Your shop closes after a covered loss | Business interruption insurance |
| A visitor trips and is injured on your premises | Commercial general liability |
Vehicle, cyber, and pollution exposures are usually added by endorsement or a separate policy. Read the exclusions before you sign.
Is Commercial Liability Insurance Required for a Sole Proprietorship?
No federal rule requires a sole proprietor to carry liability insurance simply because they are in business. Requirements arrive from other directions:
- Contracts and clients — many commercial agreements set a minimum limit and require a certificate of insurance.
- Landlords — commercial leases routinely require tenant liability coverage.
- Provincial licensing and regulators — trades, health services, and some professions must show proof of coverage to hold a licence.
- Lenders and franchisors — financing and franchise agreements often mandate specific coverage.
Because a sole proprietorship is not a separate legal entity, a judgment against the business is a judgment against you personally. That is the practical reason many sole proprietors buy coverage even when nothing forces them to. See sole proprietorship liability for how personal exposure works, and whether you need business insurance in Canada for the wider picture.
Coverage Limits, Deductibles, and What Drives the Price
Most policies are quoted with a per-occurrence limit and an aggregate limit — the maximum payable for all claims in a policy period. A deductible applies to each covered claim. Insurers assess risk using several factors:
| Rating factor | Why it matters |
|---|---|
| Industry and class of business | Higher-risk work, such as roofing or food service, prices above office-based consulting. |
| Revenue and payroll | Larger operations generally carry more exposure. |
| Subcontractor use | Insurers want proof that subcontractors carry their own coverage. |
| United States or international work | Cross-border exposure may need an endorsement or a separate policy. |
| Claims history | Prior claims influence both price and willingness to insure. |
| Limits required by contract | A client-mandated limit sets the floor for your quote. |
Amounts vary widely by province, industry, and insurer, so confirm current pricing with a licensed broker rather than relying on generic figures.
How to Buy Commercial Liability Insurance in Canada
- Confirm the limits your contracts, lease, or regulator require — in writing.
- Write down your operations, revenue, subcontractor use, and any US work.
- Contact a licensed insurance broker or agent in your province; they can approach multiple insurers.
- Compare quotes on limit, deductible, exclusions, defence-cost treatment, and whether the policy is occurrence-based or claims-made.
- Ask for a certificate of insurance to give clients or landlords, and keep a copy on file.
- Review coverage at renewal and report changes in revenue, services, or locations promptly.

Keeping Coverage Aligned With Your Business
Insurance is not a one-time purchase. Add a service line, hire your first employee, start shipping to the United States, or sign a commercial lease, and your exposure changes. Tell your broker before a change takes effect, not after a claim. Keep policy documents, certificates, and renewal notices with your other business records, and confirm the tax treatment of premiums with a qualified accountant — liability insurance premiums are commonly deductible as a business expense, but your situation may differ.

Frequently asked questions
Is commercial liability insurance mandatory for a sole proprietorship in Canada?
No. There is no federal requirement that a sole proprietor carry commercial liability insurance. It is often required indirectly, though: commercial leases, client contracts, franchise agreements, lenders, and some provincial licensing bodies may demand proof of coverage before working with you. Because a sole proprietorship is not a separate legal entity, an uninsured claim can reach your personal assets, which is why many sole proprietors buy a policy anyway. Confirm any specific requirement with your province or industry regulator.
What is the difference between commercial general liability and professional liability?
Commercial general liability responds to third-party bodily injury and property damage arising from your premises, operations, products, or completed work. Professional liability, also called errors and omissions, responds when a client claims your advice, design, or service was negligent and caused them a financial loss. Many service businesses need both, and some insurers sell them together in a package. Check your policy wording, since the boundary between the two can be narrow.
How much does commercial liability insurance cost for a small business in Canada?
Premiums vary widely depending on industry, revenue, location, coverage limit, deductible, and claims history, so there is no standard price. Office-based consultants generally pay less than trades or food-service businesses. Brokers can often quote several insurers at once, which makes comparing limits and exclusions easier. Rather than relying on averages you find online, request quotes based on your own operations and confirm current pricing with a licensed broker in your province.
What coverage limit should a small business carry?
Start with the minimum your contracts, lease, or regulator requires, then consider what a serious injury or property damage claim could cost. Policies are commonly quoted with a per-occurrence limit and a higher aggregate limit for the policy period. Higher limits cost more, but a low limit can leave you paying the difference personally. A licensed broker can help you match limits to your actual exposure.
