Question 1

Doesn't commercial general liability already cover pollution?

Accepted Answer

Commercial general liability may address certain third-party injury or property-damage claims, but most CGL forms contain pollution exclusions — from legacy sudden-and-accidental wording to modern absolute or total pollution exclusions that restrict gradual contamination and many cleanup costs. Whether a specific loss falls inside or outside CGL depends on policy wording and how the claim is framed — not on a simple rule that GL never covers pollution or always covers sudden spills. Pollution liability or environmental impairment coverage may be arranged where operations and exclusions create a gap.

Question 2

Can pollution insurance address gradual contamination?

Accepted Answer

Site pollution and environmental impairment forms — where purchased on a claims-made or occurrence basis depending on market — are designed for gradual leaks and long-term contamination that CGL exclusions often restrict. Triggers, retroactive dates, and known-condition exclusions still apply; gradual does not mean automatic or unlimited. Contractors pollution liability may address pollution conditions caused during your operations, subject to the same policy constraints.

Question 3

What cleanup costs may be covered?

Accepted Answer

Insured cleanup and remediation costs — investigation, emergency response, soil and groundwater remediation, and related third-party claims — may be covered when the pollution policy trigger is satisfied and exclusions do not apply, subject to limits and deductibles. Defence costs often share the same limit. Statutory duties under Ontario environmental law continue regardless of insurance; fines and penalties are generally not insurable.

Question 4

Can existing contamination be insured after it is discovered?

Accepted Answer

Known pollution conditions identified before policy inception are typically excluded — insurers do not accept transfer of existing remediation obligations through a new policy after discovery. Undisclosed pre-existing conditions can jeopardize coverage. Some programs may offer limited coverage for unknown historical conditions with appropriate retroactive dates and environmental assessments, but already-identified contamination requires remediation planning outside standard new-policy placement.

Question 5

Who should consider pollution liability insurance?

Accepted Answer

Businesses with meaningful environmental exposure — contractors doing excavation or remediation, manufacturers using chemicals, property owners with storage tanks, fuel operations, waste handlers, transporters of pollutants, and developers on former industrial sites — may need pollution coverage when contracts or CGL exclusions create gap risk. Not every business requires a pollution policy; a broker review of operations, site history, and existing liability wording clarifies whether specialized coverage is warranted.

Practical considerations

Site history and environmental assessmentsKnown or suspected contamination from prior owners, underground tanks, or industrial use affects eligibility and pricing.

Operations and materials handledChemicals, solvents, refrigerants, fuels, paints, and process waste each carry different exclusion and sublimit patterns.

Storage tanks — UST and ASTUnderground and above-ground storage tanks require registration, maintenance, and often specific tank schedules on pollution or property programs.

Contractual requirements for contractorsProject owners, municipalities, and prime contractors may mandate contractors pollution liability with minimum limits and additional-insured status.

Transportation and waste disposal pathsHauling waste, recyclables, or chemicals off-site may need transportation pollution coverage or non-owned disposal site extensions where available.

Known pollution conditions and disclosurePollution discovered before policy inception — or known to the insured and not disclosed — is typically excluded.

Claims-made triggers and retroactive datesMany pollution policies are claims-made: the claim must be reported during the policy period (or extended reporting period if purchased).

Regulatory cleanup vs insurable remediationOntario law may require spill reporting, mitigation, and remediation under the Environmental Protection Act — independent of insurance.
