Small Business Week runs October 19 to 25, and it is a useful moment for Ontario business owners to ask a question that rarely gets asked at a good time: does your commercial policy still match the business you actually run today? Most coverage gaps are not discovered during a review. They are discovered after a loss, when a claim is denied or falls short, and by then the fix is no longer available. The patterns below show up again and again in commercial policy reviews. None of them requires a dramatic mistake. Each one starts with a business that changed while its policy stayed the same.
Leased Space Without Tenant's Legal Liability
Many Ontario businesses lease their premises. A commercial general liability policy does not always include coverage for damage the business causes to the building it occupies. That protection usually comes from tenant's legal liability coverage, which responds when the tenant is legally responsible for damage to the landlord's property, for example after a fire that starts in the leased unit. Without it, a business can face a repair bill for someone else's building on top of its own losses. Landlords often require this coverage in the lease, but leases are not always checked against the policy after signing.
Staff Driving Personal Cars on Company Business
When employees run errands, visit clients, or pick up supplies in their own vehicles, the business can face liability if one of them causes a collision while on company business. Personal auto policies typically cover the driver, but they may not cover the employer, and they may exclude or limit coverage for business use. Non-owned auto coverage is designed for this exposure. It is one of the most commonly missing coverages for businesses that do not own a fleet, precisely because owners assume that no company vehicles means no auto exposure.
Growth the Policy Never Caught Up With
A policy written when a business had one location, a handful of employees, and modest revenue can quietly become inadequate as the business grows. Revenue, payroll, staff count, locations, equipment, and services offered all feed into how a commercial policy is priced and structured. When any of them change, limits that once fit may no longer reflect the value at risk, and new activities may fall outside the described operations. A catering company that adds delivery, a contractor that adds a second crew, or a retailer that opens an online store has changed its risk profile, whether or not anyone told the broker.
Business Interruption and Extra Expense
After a fire or flood, the property damage is only part of the loss. Rent, payroll, loan payments, and other fixed costs continue while the business is closed or operating at reduced capacity. Business interruption coverage is meant to replace lost income during the restoration period, and extra expense coverage helps pay the additional costs of keeping the business running, such as a temporary location or rush equipment replacement. Businesses that carry property coverage but skip interruption coverage often find they can rebuild the premises but cannot survive the months without income.
Cyber Exposure in Small Businesses
Even a small business usually holds customer names, contact details, payment information, or employee records. A ransomware incident, a breached email account, or a lost laptop can trigger notification obligations, forensic investigation costs, and lost business. Many owners assume cyber risk belongs to larger companies. Smaller businesses are often targeted precisely because their defences are lighter. Standalone cyber coverage or a cyber endorsement can address costs that a general liability policy typically does not.
Equipment Breakdown
Heating systems, refrigeration units, production machinery, and specialized equipment can fail without warning. Equipment breakdown coverage responds to sudden and accidental mechanical or electrical failure, which a standard property policy often excludes. For a restaurant, a failed walk-in cooler can mean a full inventory loss in a night. For a manufacturer, a failed compressor can halt production for days. The coverage is inexpensive relative to the loss it addresses, and it is easy to overlook until the first failure.
Sewer Backup and Flood on Commercial Property
Fall is claim season for water damage in Ontario. Sewer backup coverage is often a separate endorsement with its own limit, and overland flood coverage is not automatically included in every commercial property policy. A business in a low-lying area, or one with inventory stored at floor level, should know exactly which water perils its policy covers and at what limit. After a storm, the difference between a backup endorsement and no endorsement can be the difference between a covered cleanup and a bill paid entirely out of pocket.
What a Review Looks Like
A useful review starts with the facts of the business as it operates today: the exact legal entity name on the policy, revenue, payroll, number of employees, locations, equipment values, and any contracts that require certificates of insurance for landlords or clients. It then compares those facts against the policy: limits, deductibles, listed locations, described operations, endorsements, and exclusions. The goal is not to buy more insurance for its own sake. It is to find the places where the business and the policy disagree, and to close the ones that matter before a claim tests them.
The Bottom Line
Coverage gaps are rarely dramatic. They are quiet mismatches between a business that kept changing and a policy that did not. Small Business Week is a good time to close them, because the review takes less time than most owners expect, and it is far cheaper than discovering a gap after a loss. If your business has changed since your policy was written, that is the signal to review it now, not at renewal.
