Short answer: Alberta law doesn’t generally require a small business to carry liability insurance, but most businesses benefit from it, and many are asked for it. Business liability insurance in Alberta, usually called commercial general liability (CGL), can help pay legal defence costs and damages if your business is found responsible for injuring someone or damaging their property. Landlords, clients and contracts often require proof of it before you can start work.

Whether you run a shop in Airdrie, a trades business out of your truck, or a consulting practice from your kitchen table, one claim can be expensive. Here is what CGL is, what it typically covers and doesn’t, and how to tell how much you need.

What is business liability insurance?

Commercial general liability (CGL) insurance covers amounts your business is legally obligated to pay others for bodily injury or property damage caused by your operations, premises, products or completed work. It also typically pays the legal costs to defend you in a covered lawsuit. Insurance Bureau of Canada (IBC) lists CGL among the most common commercial coverages.

A few everyday examples:

• A customer slips on an icy entrance at your storefront and is injured.
• Your crew accidentally damages a client’s flooring while installing cabinets.
• A product you sold is alleged to have caused an injury.

Whether a specific claim is covered depends on your policy wording, limits and exclusions.

Does my small business need liability insurance in Alberta?

Even when the law doesn’t require it, you may need it to do business:

• Commercial leases commonly require tenants to carry liability insurance and name the landlord.
• Contracts and job sites often require a certificate of insurance with a minimum limit before you start.
• Some licences, permits and associations ask for proof of liability coverage.

Beyond those requirements, ask yourself: if someone sued my business tomorrow, could I pay a lawyer and a settlement out of pocket?

What does CGL not cover?

CGL is one piece of a business insurance program. It typically doesn’t cover:

• Your own property, such as your building, equipment and inventory. That’s commercial property insurance.
• Lost income after a covered loss. That’s business interruption coverage, usually added to a property policy.
• Professional mistakes or advice. If you’re paid for professional services or advice, you may need professional liability, also called errors and omissions (E&O).
• Vehicles. Vehicles used for business need proper auto or commercial auto coverage.
• Cyber incidents, such as a data breach or ransomware, which usually need cyber insurance.
• Injuries to your own workers. In Alberta, most employers must have WCB coverage for their workers, and it’s separate from CGL.

Running a business from home?

IBC notes that personal liability on a homeowner’s policy typically won’t cover claims arising from your business, and home policies usually have only a small limit for business equipment. Tell your home insurer about any business on the premises, and ask us whether you need a home-based business policy or separate commercial coverage.

How much liability coverage do I need?

There isn’t one right number. Your limit depends on your industry, the size of your jobs, what your contracts and landlord require, and your exposure. IBC notes that some businesses, such as those that serve alcohol, have higher liability risks and need higher limits. A broker can compare options from several insurers and help you match your limit to your risks.

Small business insurance checklist

1. Gather your contracts and lease and note any insurance requirements.
2. List what you own: equipment, tools, stock and improvements.
3. Think about what could go wrong: injuries, damage to client property, product problems, errors in advice, data loss.
4. Check WCB-Alberta requirements if you have or plan to hire workers.
5. Review your coverage every year as your business grows.

Frequently asked questions

Is liability insurance mandatory for businesses in Alberta?

Not as a general rule, but leases, contracts, licences and clients often require it. Auto insurance for vehicles and WCB coverage for most employers are separate requirements.

What is a certificate of insurance?

It’s a document from your insurer or broker that shows your coverage and limits. Clients and landlords often ask for one before you start work.

Does CGL cover my tools if they’re stolen?

No. CGL covers your liability to others. Tools and equipment need property or equipment coverage.

I’m a sole proprietor. Do I still need it?

Size doesn’t change your liability. Many sole proprietors carry CGL, especially if they work at clients’ homes or job sites.
