Designated Substance Survey

We provide expertise in the design phase of building renovations, infrastructure upgrades, or demolition projects to prevent additional costs and project delays in the case where designated substances may be found.

A Designated Substance Survey determines the presence, location, and concentration of any of the eleven designated substances that are deemed toxic and of particular concern under O. Reg. 490/09 Designated Substance, including asbestos and lead.

The Ontario Occupational Health and Safety Act requires that all designated substances be identified and removed before a demolition or renovation. This allows contractors to take the steps necessary to control exposure throughout demolition or renovation.
