Most business owners buy a commercial general liability policy expecting it to be a catch-all for anything that goes wrong. It is a broad policy, but it is not unlimited, and understanding what a commercial general liability policy typically excludes matters just as much as understanding what it includes. The gaps are where a business can end up uninsured for a real exposure without realizing it until a claim happens.
This article walks through the standard carve-outs that appear in most Canadian CGL forms, why insurers build the policy this way, and where a business typically finds a separate product to address the gap.
What is a commercial general liability policy?
A commercial general liability policy (CGL) is a form of business insurance that is generally designed to address third-party claims for bodily injury, property damage, and certain advertising or reputational offenses arising from a business's operations, products, or premises. It is often the foundation of a business's liability protection, but the standard form is built around a defined set of insuring agreements, and everything outside those agreements is either excluded outright or left to a different policy.
Because the CGL form is standardized across most Canadian insurers, the exclusions tend to look similar from one policy to the next, even though the exact wording, endorsements, and any buy-back options can vary by insurer. That consistency is useful for a business owner comparing quotes, since it means the gaps are largely predictable rather than a surprise buried in fine print.
What does a CGL policy typically exclude?
A handful of exclusions show up in nearly every standard CGL form sold in Canada. According to a plain-language summary of standard commercial liability forms published by the Insurance Institute of Canada, the most common carve-outs include professional services, pollution, motor vehicle liability, aircraft and watercraft, and injuries to a business's own employees.
The logic behind most exclusions is the same: the CGL form is the general-purpose layer, and anything with its own dedicated insurance product is generally pushed out to that product instead. A business that understands this pattern can usually predict where a gap exists before a broker points it out, though exactly which exclusions apply depends on the specific policy wording and endorsements, which only the actual policy and a licensed broker can confirm.
Damage to the business's own property
A CGL policy is typically designed to respond to damage the business causes to someone else's property, not damage to the business's own building, equipment, or stock. That exposure is generally the job of a separate commercial property insurance policy, which is built specifically to address the business's own physical assets after a fire, storm, or other covered event.
Contractual liability beyond what the law requires
Businesses that sign leases, service agreements, or construction contracts often promise to indemnify another party for losses that arise from the work. A CGL policy commonly excludes liability a business voluntarily takes on through a contract, beyond what would already exist under the law, unless the contract fits a narrow exception the policy defines. This is one reason a landlord or general contractor's insurance requirements deserve a careful read before a lease or subcontract is signed.
How do professional services and employee injury exclusions work?
Two of the most consequential CGL exclusions involve who is making the claim and what kind of work caused it.
Professional services is typically excluded because the CGL form is not built to evaluate specialized advice, design work, or technical judgment the way a professional liability policy is. A bookkeeper's calculation error, a consultant's flawed recommendation, or a technology company's faulty code generally falls outside a standard CGL form entirely, which is why the difference between CGL and professional liability insurance matters so much for service-based businesses.
Employee bodily injury is typically excluded for a related but different reason. CGL insurance is generally structured around third-party claims, meaning claims from customers, visitors, or other outsiders, while workplace injuries to a business's own staff are meant to be addressed through the provincial workers' compensation system instead. A business with staff performing physical work should confirm its workers' compensation coverage is current rather than assuming a CGL policy fills that role, and a licensed broker can confirm exactly how a specific policy's wording draws that line.
What other common CGL exclusions should a business know?
Several additional carve-outs round out the standard form, and each typically points toward a specific alternative product.
- Pollution: Contamination-related bodily injury or property damage is typically excluded under a broad pollution exclusion, with narrow exceptions that vary by insurer. Contractors and businesses that handle chemicals, fuel, or waste commonly need a separate policy, similar to how pollution liability insurance for contractors is built to fill this specific gap.
- Autos, aircraft, and watercraft: Liability tied to owning or operating a vehicle, aircraft, or watercraft is typically excluded from a CGL form and generally belongs on a dedicated auto, aviation, or marine policy instead.
- Intentional and criminal acts: Damage a business or its representatives caused on purpose, or that resulted from criminal conduct, is typically excluded from a CGL form.
- Data breaches and electronic data loss: Liability tied to a data breach or loss of electronic data is typically excluded from a standard CGL form and generally sits with a dedicated cyber liability policy instead.
A table can help summarize how the standard form is generally designed to treat each of these areas, though only the wording of an actual policy and a licensed broker can confirm what applies to a specific situation.
| Exposure | Typically excluded from CGL | Typical alternative product |
|---|---|---|
| Damage to the business's own building or stock | Typically yes | Commercial property insurance |
| Professional advice or specialized services | Typically yes | Professional liability or errors and omissions |
| Employee workplace injury | Typically yes | Provincial workers' compensation |
| Vehicle accidents | Typically yes | Commercial auto insurance |
| Pollution and contamination | Typically yes | Pollution liability insurance |
| Data breach or electronic data loss | Typically yes | Cyber liability insurance |
Benefits of knowing what a CGL policy typically excludes
Understanding these exclusions before a loss happens, rather than after, gives a business owner a clearer map of its overall risk picture. It turns an abstract sense that "insurance covers the business" into a concrete list of what each policy is generally designed to do, which makes it easier to spot a genuine gap.
It also makes shopping for business insurance in Canada more productive, since a business owner who already knows the standard exclusions can ask a broker pointed questions about which add-ons or separate policies fit the operation, rather than assuming a single CGL policy is automatically complete.
Where you'll come across CGL exclusions
These exclusions typically surface at a few predictable moments. A new business buying its first CGL policy often sees the exclusions listed in the policy wording itself, sometimes without much explanation of why each one exists. A business that signs a new lease, client contract, or municipal permit may be asked to prove coverage for an exposure, such as pollution or professional liability, that its existing CGL policy does not address.
They also come up during a policy renewal or a change in operations, such as a business adding a new service line, a fleet of vehicles, or a technology component that shifts its risk profile. A business owner reviewing what a CGL policy typically excludes at that point is often the same conversation as reviewing whether limits and endorsements still match how the business actually operates.
Talk to a licensed broker about your CGL exclusions
Every CGL policy is different in its exact wording, endorsements, and buy-back options, so the standard exclusions above are a starting point for a conversation, not a substitute for reading an actual policy. A licensed broker can walk through a business's specific operations, flag which standard exclusions genuinely apply, and help line up any additional coverage before requesting a commercial insurance quote.
Coverage details vary by insurer and by policy, and only the wording of an actual policy and a licensed broker can confirm what applies to a specific situation.
