What Does Business Liability Insurance Not Cover? 5 Common Exclusions
At Roughley, we believe insurance doesn’t have to be complicated. Part of making it better is being transparent about where your coverage ends so you aren’t left with a major expense you didn't see coming. While your liability policy is the backbone of your protection, it isn't a catch-all safety net.
Insurance is designed to cover unintentional accidents, like a visitor slipping in your Oshawa office, but it specifically excludes certain risks to ensure you have the right specialized coverage elsewhere. Understanding these gaps is the first step toward ensuring you are in the best possible position when a claim occurs.
Professional Errors and Advice
The most common point of confusion for many business owners is the difference between an accident and a mistake.
- The Exclusion: Your general liability policy covers physical accidents (like property damage), but it typically excludes claims related to your professional expertise.
- The Scenario: If your advice or specialized service causes a client a financial loss, without any physical injury involved, general liability will not respond.
- The Solution: You need Professional Liability (Errors & Omissions) to cover risks related to your specific knowledge and services.
Employee Injuries (WSIB)
Your liability policy is designed to protect you against claims from third parties, such as customers or vendors.
- The Exclusion: If one of your own employees is injured on the job, your business liability insurance does not cover their medical costs or lost wages.
- The Solution: In Ontario, workplace injuries are handled through the Workplace Safety and Insurance Board (WSIB). For many sectors, especially in commercial and manufacturing, this is a separate and mandatory requirement.
Accidents Involving Commercial Vehicles
If you or an employee are involved in a road accident while driving for business, your general liability policy will almost always stay on the sidelines.
- The Exclusion: Liability policies specifically exclude bodily injury or property damage arising from the use of an automobile.
- The Solution: You must have a dedicated Commercial Auto or Fleet insurance policy to cover vehicles used for your business operations.
Intentional or Criminal Acts
Insurance is built for the unexpected and accidental.
- The Exclusion: Any damage you or your employees cause deliberately, such as fraud, theft, or intentional harm, is strictly excluded.
- The Reality: Insurance cannot be used to protect a business from the consequences of illegal or purposeful actions.
Your Own Work and Assets
Business liability insurance is meant to pay for damage you cause to someone else's property, not your own.
- The Exclusion: Your policy will not pay to fix your own building after a fire, nor will it pay to replace your own faulty workmanship.
- The Solution: You need Commercial Property Insurance to protect your physical assets, like your equipment, tools, and office space.
