What is Contaminated Land Liability?
Contaminated land liability is the legal responsibility for cleaning up and managing land that has been polluted or environmentally damaged. Liability may apply to current owners, past owners, or parties who caused the contamination.
Why Contaminated Land Liability Matters in Real Estate
It matters in real estate because buyers and lenders must assess environmental risk before transactions. Contaminated land can affect property value, financing, redevelopment potential, and legal exposure.

A company buying an industrial site discovers historical contamination. As the new owner, they may be liable for cleanup costs under provincial environmental laws.
