Commercial General Liability Insurance Ontario: Know What Your Business Is Buying

In short

Commercial general liability insurance in Ontario, commonly called CGL, addresses certain third-party bodily injury and property damage claims arising from your business. It is not a replacement for property insurance, professional liability, commercial auto or every other protection a business might need. The activity described on the policy, the exclusions and the contract requirements matter as much as the headline limit. Buy a policy for the work you actually perform, not simply a certificate that gets you through a client's onboarding form.

Begin with a real-world liability question

Imagine a customer alleges they were injured visiting your premises, or your work accidentally damages property belonging to someone else. CGL may respond to a covered claim, including defence and damages under the policy's terms. The word covered matters. A lawsuit does not automatically fall within the policy, and a particular outcome cannot be promised before the facts and wording are reviewed.

List your daily activities before asking for a price. A consultant working from home, a retailer welcoming customers and a contractor working at other people's premises do not present identical exposures. Include subcontracting, products sold, installation work and any services added recently. A policy described as office consulting may not fit a business that now also performs physical installation. Tell your broker what happens outside the office as well as inside it.

Premises, products and completed work

Premises liability concerns the business location and related operations. Depending on the policy, CGL can also address liability connected to products and completed work. These are important distinctions for Ontario businesses that sell goods, supply materials or complete jobs before a problem becomes apparent. Ask whether the policy includes the activities you need and whether an exclusion limits a particular product or type of work.

A completed-operations discussion is not the same as asking the insurer to guarantee workmanship. Insurance is not a warranty that every defective product or poor job will be repaired at the insurer's expense. The distinction between fixing your own work and responding to resulting injury or damage deserves careful explanation. If your contracts include ongoing maintenance or performance guarantees, have the broker review those details before you accept the insurance quote.

Understand the limit and the aggregate

A policy may have a limit applying to one occurrence and an aggregate applying across specified claims during the policy period. Read both. The number printed on a certificate does not tell you whether earlier claims could reduce the remaining protection, or whether a particular category has a separate limit. Ask how defence expenses are handled, because the answer depends on the policy form and coverage involved.

There is no universal CGL limit that every Ontario small business must choose. Customer contracts, leases, the nature of the operation and the size of possible losses all influence the discussion. A contract may specify a limit, but satisfying that minimum is not the same as completing a risk review. Consider deductibles and your ability to fund uncovered costs, rather than selecting the smallest premium without understanding the trade-off.

Certificates and additional insureds need precision

A certificate of insurance is evidence of coverage, not a new policy or a guarantee that every contractual obligation is insured. If a client asks to be an additional insured, confirm whether the insurer can provide the required endorsement and what it actually does. Giving a broker the contract wording is better than summarizing it as they need to be added.

Review requirements before signing whenever possible. A contract can ask for protections the proposed policy does not include, and a certificate should not be used to imply broader coverage than exists. Report new projects, different operations and material changes to the business during the year. Your insurance documents should follow the facts, not become a substitute for them. Keep copies of certificates and endorsements alongside the relevant contracts.

The gaps CGL does not solve on its own

Professional advice and design errors may require errors and omissions insurance. Vehicles need an auto review. Cyber incidents, employee-related claims, pollution exposures and liquor service can call for separate coverage or specific endorsements. CGL should be part of a business insurance program, not an assumption that the word general means everything. Ask your broker to explain the exclusions most relevant to your particular operation.

Likewise, damage to your own building, tools, stock or equipment belongs in a property discussion. If an insured loss interrupts trading, business interruption is a separate question. The Insurance Bureau of Canada lists these as distinct business coverages for good reason. Our Ontario business insurance overview helps frame that wider review, while the CGL decision focuses on your liability to others.

Prepare an application that will survive a claims review

Bring a clear description of operations, annual revenue, employee and subcontractor information, premises details and claims history. Tell the broker about products, work outside Ontario and customer contract requirements. Estimate honestly and explain upcoming changes. Underwriting based on inaccurate activities or missing information can produce a price that looks attractive but does not represent the business the insurer is actually being asked to cover.

Compare quotations against the same operation and requested coverage. Look at exclusions, deductibles, limits, endorsements and insurer requirements alongside cost. Then review the program when the business changes, not only when the renewal arrives. Truly Insurance is based in Kitchener–Waterloo, serving all of Ontario. Start a business insurance quote with your operations and contract details, and a broker can help separate the certificate you need today from the protection your business needs tomorrow.
