Environmental Liability: Canada's New Risk Reality

Why It Matters

PFAS liability is becoming a mainstream exposure; without proactive risk assessment and appropriate insurance, Canadian firms risk uncovered remediation costs and contract disqualification.

Key Takeaways

• PFAS classified toxic, prompting phased bans across Canada
• Insurers adding case‑by‑case exclusions for historic PFAS contamination
• Quantifying legacy soil and groundwater PFAS proves costly and complex
• Contractors now required to carry dedicated pollution liability policies
• Integrated casualty‑environmental products emerging to close coverage gaps

Summary

The panel discussed Canada’s new environmental liability landscape as the federal government moves to label per‑ and polyfluoroalkyl substances (PFAS) toxic and phases out their manufacture, sale and use, beginning with firefighting foams. This regulatory shift forces insurers, brokers and insureds to reassess site‑pollution, product‑pollution and legacy‑contamination exposures under Canadian environmental policies.

Speakers highlighted three practical challenges. First, the historical PFAS footprint is ubiquitous, making it difficult and expensive to quantify legacy soil and groundwater contamination. Second, insurers are responding with granular, case‑by‑case exclusions—often adding PFAS language to pollution and casualty lines—even when policies lack explicit POS exclusions. Third, brokers are seeing a surge in demand for contractor‑pollution liability (CPL) and broader environmental programs, prompting discussions about project‑specific versus practice‑wide coverage and the rise of integrated casualty‑environmental products that bundle general liability with pollution coverages.

Notable examples included Sean’s warning that “the biggest thing is figuring out what work needs to be done to quantify the historical piece,” Amanda’s observation that many contractors now must carry CPL for tender compliance, and Justin’s explanation that integrated forms can eliminate gaps between product liability and environmental liability. The panel also referenced an August launch of a combined environmental protection insurance product that merges general liability with full pollution coverage.

The implications are clear: insurers must refine underwriting guidelines and policy forms to address PFAS‑specific risks, while brokers must educate clients on emerging exclusions and the benefits of integrated solutions. Companies face tighter regulatory scrutiny, higher remediation costs, and the need for robust environmental controls to secure affordable coverage and avoid costly gaps.

Original Description

Canada’s environmental insurance market is facing a major shift as the federal government moves to classify PFAS as toxic under CEPA, raising urgent questions around exclusions, legacy contamination and coverage certainty.

In this 2026 Insurance Business TV panel, leaders from Gallagher, Willis and Aon explain how tightening regulation, rising contractor pollution requirements and broader definitions of “pollutant” are driving demand, reshaping underwriting and pushing environmental insurance firmly into the mainstream.
