Almost every business conversation about insurance in Alberta eventually lands on the same phrase: commercial general liability insurance. A landlord asks for proof of it before handing over keys. A general contractor requires it before a subcontractor sets foot on site. A client's procurement department will not sign a contract without seeing it listed on a certificate.
Despite how often it comes up, what commercial general liability insurance actually addresses, and what it leaves out, is not always clear to a business owner hearing the term for the first time. This article walks through what CGL is generally designed to do, how its limits and deductibles typically work, and where it tends to show up in the life of an Alberta business.
What Is Commercial General Liability Insurance?
Commercial general liability insurance (CGL) is a policy designed to respond to third-party claims alleging that a business caused bodily injury, property damage, or certain advertising-related harm during its operations. Rather than covering damage to the business's own property or its own employees, CGL is generally built around claims made by someone outside the business, such as a customer, a visitor, or another company.
Think of it as the foundational liability layer most Alberta businesses carry, often alongside more specific coverages such as commercial property or commercial auto insurance, depending on what the business does and owns.
What Commercial General Liability Insurance Is Generally Designed to Address
CGL policies are typically built around three broad categories of third-party claims. The exact wording, limits, and exclusions that apply to any of these depend on the specific policy.
Bodily injury claims
If a customer, delivery driver, or visitor is hurt on a business's premises or because of its operations, such as a slip on an unmarked wet floor, a CGL policy is generally designed to respond to the resulting claim, including associated legal defence costs.
Property damage claims
CGL is also generally designed to address situations where a business's operations damage someone else's property, such as a contractor accidentally damaging a client's flooring while completing a job.
Personal and advertising injury claims
This category typically covers allegations such as libel, slander, or copyright infringement connected to a business's advertising or public statements, separate from physical injury or property damage.
How Limits, Deductibles, and Claims Generally Work
Every CGL policy carries at least two limit figures, plus a deductible that applies before the policy responds.
Per-occurrence and aggregate limits
A per-occurrence limit is generally the maximum amount a policy is designed to pay out for a single claim. An aggregate limit is generally the maximum total across every claim during the policy period, often a full year. A common structure quoted to Alberta small businesses pairs a two million dollar per-occurrence limit with a matching or higher aggregate limit, though exact figures vary by insurer and by business.
Deductibles
Most CGL policies carry a deductible that applies to each claim before the policy responds further. Deductible amounts vary considerably depending on the insurer, the industry, and the size of the business.
What generally happens when a third-party claim is made
At a high level, the process a CGL policy is designed to support typically follows a similar pattern:
- The business notifies its broker or insurer. Most policies require reasonably prompt notice once a business becomes aware of an incident or a claim.
- The insurer reviews the claim. This generally includes confirming the claim falls within the policy's coverage and limits.
- Legal defence is arranged if needed. CGL policies are typically designed to cover defence costs in addition to, not instead of, the liability limit itself, though the exact structure depends on the policy wording.
- The claim is resolved. Outcomes vary by situation, and only the policy wording and the insurer's handling of a specific file determine what applies.
What Commercial General Liability Insurance Typically Leaves Out
CGL is broad, but it is not designed to be a business's only policy. Coverage that typically sits outside a standard CGL policy includes:
- Employee workplace injuries, which are generally addressed through Workers' Compensation Board - Alberta rather than CGL.
- Professional errors or bad advice, which is generally the domain of a separate professional liability or errors and omissions policy.
- Damage to the business's own vehicles, which typically requires commercial auto insurance.
- Damage to the business's own building or equipment, which is generally addressed by commercial property insurance rather than CGL.
- Cyber incidents, such as a data breach, which typically require a dedicated cyber policy.
Because these gaps are common, many Alberta businesses carry CGL as one part of a broader package rather than as a standalone policy. Whether a specific combination of coverages fits a given business is a question for a licensed broker, since coverage varies by policy and insurer.
Benefits of Commercial General Liability Insurance
The practical upside of CGL is straightforward: a single third-party lawsuit, even one that is eventually resolved in the business's favour, can involve legal defence costs that add up quickly. CGL is generally designed to absorb both the defence costs and, where a claim is valid, the resulting settlement or judgment, up to the policy's limits. For many Alberta businesses, that protection is also what allows them to sign leases, win contracts, and take on new clients in the first place, since so many of those relationships require proof of coverage before they can proceed.
Where You'll Come Across Commercial General Liability Insurance
CGL tends to surface at a handful of predictable points in a business's life:
- Signing a commercial lease. Landlords commonly require proof of CGL, sometimes with a minimum limit, before turning over a space.
- Bidding on a contract. General contractors and larger clients frequently require subcontractors and vendors to carry CGL before work begins.
- Opening a storefront or office. New businesses are often introduced to CGL for the first time when arranging their initial commercial policy.
- Renewing a policy each year. Limits, deductibles, and premiums are reviewed at renewal as a business's operations, revenue, or claims history change.
- Requesting a certificate of insurance. CGL limits are one of the details most often shown on a certificate of insurance requested by a landlord or client.
Talk to a Licensed Broker About Commercial General Liability Insurance
