Trusted Designated Substance Survey
Services in Ontario

Why Designated Substance Surveys Matter

Before renovations, demolition, or major projects begin, Ontario law requires that designated substances be identified and documented. A Designated Substance Survey (DSS) provides a detailed inventory of regulated hazardous materials that may be present in building materials or on site, so that contractors, employers, and property owners can take proper safety measures.

Designated substances include materials such as asbestos, lead, silica, mercury, benzene, and others that are regulated under the Occupational Health and Safety Act because of their potential to harm workers and occupants.

A professional DSS helps ensure:

  • Compliance with Ontario health and safety legislation
  • Protection of workers, occupants, and contractors
  • Clear documentation for project planning, real estate transactions, and insurance
  • Confidence and efficiency before construction or demolition begins
