What Is Commercial General Liability Insurance?

Commercial General Liability (CGL) insurance protects a business against financial losses arising from claims made by third parties — customers, clients, visitors, the public, and adjacent property owners — who allege that your business caused them bodily injury or property damage. It covers the full cost of responding to those claims: legal defence, investigation, settlement negotiations, and any court-awarded damages, up to the policy's per-occurrence and aggregate limits.

CGL is not a niche or optional coverage — it is the baseline commercial insurance that every business operating in Ontario effectively needs. A retailer whose customer slips and falls on a wet floor, a contractor whose work damages a client's property, a manufacturer whose product injures a user, a service company whose employee breaks something in a client's home — all of these situations generate CGL claims. The financial consequences of a single significant liability claim — a serious injury, a major property loss, an advertising infringement lawsuit — can easily exceed the combined revenue of a small business for an entire year. CGL insurance converts that catastrophic uncertainty into a manageable annual premium.

The Three Coverage Pillars of a CGL Policy

Every standard CGL policy in Canada is structured around three core coverage areas, each addressing a distinct category of third-party claim:

Premises and Operations Coverage responds to claims arising from your business premises and your day-to-day operations — a customer injured on your property, property damage you cause while performing services, or a third-party loss arising from how you conduct your business. This is the most frequently triggered coverage in most commercial CGL policies.

Products and Completed Operations Coverage responds to claims arising from products you manufacture, sell, or distribute, and from work you have completed. A product that injures a user after it leaves your control, or a construction or service project that causes damage after completion, is addressed by this coverage. For contractors, completed operations is critical — it extends liability protection past the day a job is done.

Personal and Advertising Injury Coverage responds to non-physical injury claims — libel, slander, false arrest, invasion of privacy, and advertising injury including copyright infringement and misappropriation of ideas. These claims are less frequent than bodily injury and property damage claims but can be equally expensive to defend and resolve.

Who Needs CGL Insurance in Ontario?

The practical answer is: every business. Every business that has any contact with third parties — customers, clients, visitors, suppliers, members of the public, or adjacent property owners — faces the liability exposure that CGL is designed to address. More specifically:

Retailers and hospitality businesses face constant premises liability exposure from customer injuries on their property — slip and fall incidents, product-related injuries, and customer property damage.

Contractors and tradespeople face property damage and bodily injury exposure at every client site. Most contracts, building permits, and project owners require proof of CGL before allowing work to begin. For detailed contractor-specific CGL information, see the dedicated pages for Contractor Insurance, Construction Insurance, and the individual trade pages.

Professional service firms face premises and personal injury exposure at their offices and during client visits, in addition to the professional services exposure addressed by Professional Liability (E&O) insurance.

Manufacturers and distributors face products liability exposure for physical harm caused by the goods they produce or sell.

Property owners and landlords face premises liability for injuries to tenants, visitors, and the public on their properties.

Service businesses of every kind — cleaning, maintenance, delivery, technology installation, food service — face liability for damage and injury that occurs in the course of delivering their services.

What Does CGL Insurance Cover?

Bodily Injury to Third Parties

CGL covers claims for physical injury sustained by third parties — customers, visitors, clients, passersby, and members of the public — as a result of your business operations or premises conditions. Bodily injury claims can include medical expenses, lost income, rehabilitation costs, pain and suffering damages, and in severe cases, long-term disability or death benefits.

Property Damage to Third-Party Property

CGL covers claims for physical damage to property belonging to third parties — clients, customers, neighbours, and the public — caused by your business operations, your employees, or your products. Property damage claims can range from minor incidents (a broken window, a damaged fence) to major losses (a fire caused by your operations, flooding from a service error).

Personal and Advertising Injury

CGL covers non-physical injury claims arising from certain acts in the course of your business, including:

Products Liability

CGL covers claims arising from products your business manufactures, sells, distributes, or supplies that cause bodily injury or property damage to users or third parties. Products liability claims arise after the product has left your control — which is why this coverage is distinct from the premises and operations section of the policy.

Completed Operations

CGL covers claims arising from work you have completed — services, installations, repairs, and construction — that later cause bodily injury or property damage. A completed-operations claim arises after the contractor or service provider has finished the job, been paid, and left the site. For contractors particularly, completed operations is one of the most important elements of CGL coverage.

Legal Defence Costs

CGL covers all costs of defending a claim — lawyers, expert witnesses, investigation costs, court fees, and appeal costs — from the moment a claim or potential claim is reported, regardless of whether the underlying claim has merit. Defence costs are paid in addition to the damages limit in most CGL policies. In Canada, CGL defence cost structures vary — some policies pay defence costs outside the policy limits (which does not erode the limits available for damages), while others include defence costs within the limits. This distinction matters for businesses facing high-frequency or complex claims.

What CGL Does Not Cover

Understanding the exclusions in a CGL policy is as important as understanding what it covers. Common and significant exclusions include:

Professional services exclusion: CGL does not cover claims arising from the rendering of, or failure to render, professional advice or services. An accountant whose tax advice causes a client financial loss, an architect whose design error causes a structural failure, or a contractor who provides specification advice that proves defective — none of these is covered by CGL. These claims require Professional Liability (E&O) insurance.

Pollution exclusion: Standard CGL policies contain a broad pollution exclusion that removes coverage for claims arising from the release of pollutants — broadly defined to include many chemicals, contaminants, and irritants beyond obvious environmental pollutants. Businesses with pollution exposure need Pollution Liability insurance.

Your own property: CGL covers damage to others' property, not your own property. Your building, equipment, inventory, and contents are covered by Commercial Property insurance.

Employee injuries: CGL does not cover injuries to your own employees — those claims are governed by WSIB in Ontario.

Intentional acts: CGL covers accidental and unintended injury and damage, not deliberate acts.

Cyber liability: Standard CGL policies do not cover losses arising from data breaches, cyber attacks, or digital information theft. These require Cyber Liability insurance.

Auto liability: Liability arising from the use of vehicles is covered by commercial auto policies, not CGL.

Key CGL Policy Terms Every Business Owner Should Understand

Per-Occurrence Limit

The maximum amount the insurer will pay for any single claim or incident. The per-occurrence limit is the most commonly cited CGL limit in contracts and lease agreements. If a single slip-and-fall incident results in $1.5 million in damages and your per-occurrence limit is $2 million, the insurer pays the full $1.5 million claim.

Aggregate Limit

The maximum amount the insurer will pay across all claims in a policy year. Once the aggregate limit is exhausted by claims, no further coverage is available until the policy renews. For businesses with high claim frequency or multiple simultaneous active claims, the aggregate limit is as important as the per-occurrence limit.

Products and Completed Operations Aggregate

Most CGL policies carry a separate aggregate limit specifically for products and completed operations claims. This is distinct from the general aggregate. Contractors and manufacturers with significant products and completed operations exposure should confirm that this aggregate is adequate relative to their annual revenue and claim history.

Additional Insured

An Additional Insured is a party other than the named insured who is given coverage rights under the policy. Contracts frequently require businesses to name clients, property owners, general contractors, and landlords as Additional Insureds. When a third party is named as Additional Insured, they have direct coverage rights under the policy for claims arising from the named insured's operations.

Waiver of Subrogation

Subrogation is the insurer's right to pursue recovery from a third party responsible for a loss after paying a claim. A Waiver of Subrogation endorsement prevents the insurer from seeking recovery against the party named in the waiver. Many contracts require contractors and service providers to include a Waiver of Subrogation in favour of the project owner or client.

Primary and Non-Contributory

A Primary and Non-Contributory endorsement specifies that the named insured's policy responds first — before any other insurance the Additional Insured may carry — and that the named insured's insurer cannot seek contribution from the Additional Insured's policy. This wording is standard in many commercial and institutional contracts.

CGL Limits: How Much Do Ontario Businesses Need?

CGL limit requirements in Ontario vary by industry, client type, and specific contract requirements. General benchmarks:

Business Type Typical Minimum Required Common Maximum
Small retail / service business $1 million per occurrence $2 million
Contractor / tradesperson $2 million per occurrence $5 million
Commercial property tenant $2 million per occurrence $5 million
Commercial / institutional contractor $5 million per occurrence $10 million+
Municipal or government contracts $5 million per occurrence $10 million+

Higher limits above primary CGL are most cost-effectively achieved through a Commercial Umbrella or Excess Liability policy rather than increasing primary limits.

Frequently Asked Questions About CGL Insurance in Ontario

Is CGL insurance mandatory in Ontario?

Ontario law does not universally mandate CGL for all businesses, but it is effectively mandatory for most commercial operations. Virtually every commercial lease requires tenants to carry CGL. Most contracts with clients, general contractors, property managers, and institutional buyers require proof of CGL. Municipal permits for construction and events frequently require CGL as a condition of permit issuance. Operating without CGL exposes your business to unlimited personal and corporate financial liability for third-party claims.

How much does CGL insurance cost in Ontario?

CGL premiums vary widely based on industry, annual revenue, number of employees, claims history, and coverage limits. A small retail business or sole proprietor service provider might pay $600 to $1,500 per year for a $2 million CGL policy. A mid-size contractor with significant operations might pay $3,000 to $10,000 or more. Comparing quotes from multiple A-rated carriers through Boardwalk Insurance typically yields the most competitive pricing for your specific risk profile.

Does CGL cover professional advice I give to clients?

No. CGL contains a professional services exclusion that removes coverage for claims arising from professional advice, design, or services. If a client suffers a financial loss because of advice or professional services you provided, that is a Professional Liability (E&O) claim, not a CGL claim. Businesses that provide both physical services and professional advice typically need both CGL and E&O insurance.

What is the difference between per-occurrence and aggregate limits?

The per-occurrence limit is the maximum paid for any single incident. The aggregate limit is the maximum paid across all incidents in the policy year. If you have a $2 million per-occurrence limit and a $4 million aggregate, the insurer will pay up to $2 million on any individual claim, but no more than $4 million in total across all claims in the year. Once the aggregate is exhausted, no further coverage is available until renewal.

Does CGL cover my employees?

CGL covers injury claims made against your business by third parties — customers, clients, visitors, and the public. It does not cover injuries sustained by your own employees in the course of their employment. Employee workplace injuries are governed by WSIB in Ontario, which may be mandatory for your business depending on your industry. CGL also does not cover wage replacement or medical costs for injured employees — that is WSIB's function.

What is an Additional Insured and do I need to add them?

An Additional Insured is a party named in an endorsement to your CGL policy who receives direct coverage rights for claims arising from your operations. Many commercial contracts, leases, and project agreements require you to name the other party — your client, your landlord, or the general contractor — as an Additional Insured. When you do this, they can make a direct claim under your policy. Whether you are required to add an Additional Insured depends on the specific contract you have signed. Boardwalk Insurance issues Additional Insured endorsements same-day.

Is CGL the same as business insurance?

CGL is a component of business insurance — the liability protection component. A complete business insurance program typically includes CGL plus Commercial Property (protecting your physical assets), Commercial Auto (for business vehicles), and depending on your business, Professional Liability, Cyber Liability, and other specialty coverages. "Business insurance" is a general term; CGL is the specific policy that addresses your liability to third parties.
