What Is Pollution Liability Insurance in Canada?

Picture this: you’re hired to remove mould from a client’s home. You do everything right, but some of it remains. Weeks later, the client develops a respiratory illness and files a lawsuit against your company. Without the right coverage, that claim comes out of your pocket.

Contractors pollution liability insurance covers third-party claims for bodily injury, property damage, and legal and cleanup costs caused by hazardous pollutant exposure from your operations, both during and after a job.

What Is Pollution Liability Insurance in Canada?

Pollution liability insurance – also called environmental liability insurance – is a business policy that protects self-employed professionals and business owners from the financial fallout of pollution incidents.

It covers cleanup costs, legal fees, and damages when your operations result in the sudden or gradual release of pollutants into water, soil, or air that harm people or property. 

What Does Pollution Liability Insurance Cover in Canada? 

A pollution liability policy covers gradual or sudden environmental damage on a covered site. Here’s what that includes:

Covered incidents: 

• Third-party bodily injuries
• Third-party property damage

Following a claim, your policy can pay for:

• Lawsuit defence costs and damages from third-party bodily injury or property damage claims 
• Civil fines, penalties, and environmental assessments
• Emergency response and management costs 
• Cleanup and disposal expenses
• Transportation liability exposures while hazardous materials or waste are being loaded, unloaded, or transported
• Environmental risks contractors may face from ongoing or completed projects, including mould removal, asbestos abatement, excavations, and more

Who Needs Pollution Liability Insurance in Canada?

Here’s the short answer: if your business uses, manages, or disturbs any kind of toxic or hazardous material, you need this coverage. Any business that uses toxic chemicals or materials could face a third-party pollution liability lawsuit. 

That’s a longer list than most business owners expect: 

• General contractors and construction professionals
• Landscaping and lawn care companies
• Professional cleaning companies
• Commercial building and property owners
• Dry-cleaning services
• Excavation and concrete contractors
• Pest control professionals
• Hair salons
• Food and beverage manufacturers
• Spray painters
• Auto repair shops and dealerships
• Fuel and oil companies
• Gas stations and car washes
• Junkyards
• Industrial manufacturers

Contractors and subcontractors in the construction industry are particularly at risk. Work like mould remediation, asbestos removal, fire restoration, and drilling can all lead to bodily injuries and property damage. Accidentally striking a natural gas line while drilling? That’s a pollution incident, and a standard commercial general liability (CGL) policy won’t cover it.

That’s the misconception that leaves a lot of contractors dangerously underinsured. Most people assume only businesses dealing with hazardous waste need this coverage. In reality, nearly all contractors face pollution-related risks that a standard general liability policy simply doesn’t cover.

What to Look for in a Pollution Liability Insurance Policy

Not all pollution liability policies are the same. Here’s what to pay attention to when comparing coverage:

• Types of coverage available. Look for policies that address pre-existing and new pollution conditions, cleanup costs triggered by regulatory requirements, and legal expense coverage for third-party claims against your business.
• Scope of coverage. Most policies include exclusions for certain bodily injury and property damage claims. Third-party bodily injury coverage typically includes injuries, sickness, and death, but some policies don’t cover mental and emotional injuries, and none cover ‘virus removal’ services.
• Voluntary discoveries. Some policies exclude cleanup costs for environmental contamination you voluntarily find. For example, unearthing contamination during a routine drilling operation. Some insurers include this exclusion to prevent fraudulent claims, so it’s worth confirming how your policy handles this scenario.

How Much Does Pollution Liability Insurance Cost in Canada?

Pollution liability insurance typically costs around $3,500 per year for a policy with a $2 million coverage limit, but your actual premium depends on the specifics of your business.

Factors that affect your premium include:

• Your province or territory
• The nature of services you provide
• The types of hazardous materials you use or manage
• Your professional certifications and training
• Your experience in your industry
• Annual gross revenue
• Number of employees
• Previous pollution liability claims

Frequently Asked Questions About Pollution Liability Insurance in Canada

Do contractors need pollution liability insurance?

Yes. Most contractors should carry pollution liability insurance, especially if their work involves any risk of releasing pollutants.

Is pollution liability insurance mandatory in Canada?

What is the difference between premises pollution liability and contractors pollution liability?

The key difference is where the coverage applies. Contractors pollution liability covers environmental hazards that arise from your job-site activities and contracting work. Premises pollution liability covers risks tied to a specific property you own or operate. If you’re a contractor working on client sites, contractors pollution liability is the coverage you need.
