5 Real-World Examples of Liability Claims in Ontario (And How to Avoid Them)

By Rob Roughley

At Roughley, we believe insurance doesn’t have to be complicated. But we also know that a single liability claim can be devastating for an Ontario business if you aren't prepared. Whether you are operating a shop in Oshawa or a farm in Port Perry, accidents and mistakes are part of doing business.

Understanding the risks is the first step toward protection. Here are five real-world examples of liability claims seen across Ontario and, more importantly, how you can avoid them.

1. The Winter Slip-and-Fall (Bodily Injury)

The Scenario: In a classic Ontario winter, a customer enters a retail store in Durham Region after a heavy snowfall. The entryway is damp from melted slush, and the owner forgets to put up a "Caution: Wet Floor" sign. The customer slips, breaks their leg, and sues for medical costs, lost wages, and pain and suffering.

  • Average Cost: Slip-and-fall claims in Ontario typically range from $10,000 to $50,000, but legal fees can push this much higher.
  • How to Avoid It:
    • Implement strict snow and ice removal protocols for your parking lot and sidewalks.
    • Keep "Wet Floor" signs near every entrance during rain or snow.
    • Use heavy-duty, absorbent floor mats to catch moisture at the door.

2. The Contractor’s Overflow (Property Damage)

The Scenario: An appliance installer in the GTA is working on a kitchen renovation. A team member forgets to shut off a water valve, leading to a flood that seeps into the walls and the finished basement below. The homeowner sues for $75,000 in restoration and repair costs.

  • How to Avoid It:
    • Develop and enforce a standard checklist for every job site (e.g., "Check all valves before leaving").
    • Ensure all employees are trained on emergency shut-off procedures for water, gas, and electricity.
    • Carry Completed Operations Liability to cover damage that occurs after a job is "done".

3. The Design Flaw (Professional Liability)

The Scenario: An Ontario architect makes a calculation error in a set of blueprints for a commercial building. The mistake isn't caught until construction is well underway, leading to massive delays and a $200,000 bill for structural rework. The client sues the architect for professional negligence.

  • How to Avoid It:
    • Maintain clear, written contracts that outline the exact scope of your services.
    • Use a peer-review system where a second set of eyes checks all critical calculations or advice before it is finalized.
    • Always keep detailed documentation of client approvals and changes.

4. The Social Media Slip-Up (Advertising Injury)

The Scenario: A local cleaning company runs a social media campaign trying to be funny. An employee makes a disparaging comment about a competitor’s poor quality work. The competitor files a defamation lawsuit, claiming the post damaged their reputation and caused them to lose clients.

  • How to Avoid It:
    • Create a social media policy that prohibits mentioning competitors by name.
    • Require an owner or manager to approve all public-facing content before it goes live.
    • Ensure your Commercial General Liability (CGL) includes "Personal and Advertising Injury" coverage.

5. The Defective Product (Product Liability)

The Scenario: A local manufacturer sells organic pesticide to a customer in Ontario. The packaging has a faulty seal, causing the customer to inhale concentrated vapors that trigger a severe respiratory reaction. The customer sues for $100,000 in medical damages.

  • How to Avoid It:
    • Conduct regular quality control inspections on both the product and its packaging.
    • Include clear warning labels and usage instructions on every item you sell.
    • Work with your broker to ensure you have Product Recall insurance in case a batch needs to be pulled from shelves quickly.

A Heads-Up for 2026

While we're talking about liability, please keep in mind that Ontario's auto insurance system is changing on July 1, 2026. Most accident benefits will become "opt-in," meaning you’ll need to be proactive to ensure you and your employees are properly covered for things like lost wages and caregiver expenses.
