When it comes to contaminated property and its impacts to the environment, there is more than meets the eye. What may first come to mind are rusted barrels, oil stains, impacted soil and groundwater, industrial operations, service stations, dry cleaners, excavation and remediation and other more high-tech remedial options.

It is vapour intrusion.
Across Canada, there is limited consistency in how vapour intrusion is regulated.
