What is commercial general liability insurance?

May 15, 2026

Commercial general liability insurance (also known as business liability insurance) is designed to protect you if a third party makes a claim of harm related to bodily injury, property damage, personal injury or advertising injury. Running a business comes with enough worries—commercial general liability insurance can take a major source of stress off your plate by helping cover legal defence costs, settlements and damages, even if a third-party claim turns out to be unfounded.

Who is commercial general liability insurance for?

Commercial general liability insurance makes sense for businesses of all sizes, including small and very small businesses. In the early days when you’re still figuring things out, mistakes are bound to happen. This type of coverage can protect your business if something goes wrong.

Industries that can benefit from commercial general liability coverage and key risks

If your company interacts with clients or the public, or if it has care, custody or control of third-party property, you can be exposed to risks. Here are some industries that commonly require commercial general liability coverage, along with examples of situations where a business in that sector might face liability claims:

  • Professional services and beauty care businesses

A client slips on a wet floor or trips over an electrical cord.

  • Construction

You could accidentally puncture a water pipe while installing drywall, causing extensive damage to your client’s property.

  • Retailers and wholesalers

Your employee accidentally injures a customer while handling merchandise or unintentionally causes damage during a delivery to a client. Or a customer trips over some merchandise.

Real estate firms, condominium corporations, healthcare service providers and manufacturers are also strong candidates for commercial general liability insurance.

On the other hand, companies that provide professional advice, expertise or services rather than physical products are often good candidates for errors and omissions insurance. This includes businesses like consultants, IT companies and financial service providers, where a mistake or oversight could lead to financial loss for a client.

Is commercial general liability coverage mandatory?

Commercial general liability insurance isn't mandatory for most businesses in Canada, but it is highly recommended. In practice, landlords often require proof of insurance as part of commercial lease agreements. Clients may also require it before they agree to do business with you.

What does commercial general liability insurance cover?

Commercial general liability insurance can help protect your company if a third party makes a claim or takes legal action after suffering bodily injury, property damage, or certain types of losses. Dealing with a claim can be stressful, but it can be reassuring to know you’ve got protection to help cover legal costs if you’re sued. Not to mention coverage for compensation owed if your business is held liable, provided the claim falls within the terms of your policy.

Commercial general liability insurance typically covers four main types of claims:

  • Bodily injury and property damage

Claims involving third-party injuries or property damage caused by your business operations, premises, products or completed work. These represent the vast majority of claims

  • Personal injury and advertising injury

Covers things like slander, libel, reputational harm and copyright infringement related to your advertising or communications.

  • Medical expenses

Covers certain medical costs, such as first aid or ambulance services, for third parties injured on your premises, even if you aren’t responsible.

  • Tenant’s legal liability

Protects your business if damage, such as fire or water damage, is caused to the rented space.

What commercial general liability insurance doesn't cover

Commercial general liability insurance covers many common business risks, but it does have some gaps. Cyber incidents like data breaches and ransomware require separate cyber liability insurance. Commercial general liability insurance doesn’t cover business interruptions either, such as lost income if your business has to shut down for a while due to a covered loss or to equipment breakdown caused by mechanical or electrical failure. Each of these examples would require separate standalone coverage.

  • Assess the specific risks your business faces
