Designated Substances


Are you a commercial property owner or manager considering a major renovation project?


Do you have the staff and time to investigate the appropriate methods of disposal or recycling of any hazardous waste materials that might be found in your building?


Do you need a professional report that documents all activities performed by an abatement contractor?


What is a Designated Substance?


In Ontario, there are 11 designated substances that are regulated to protect or minimize exposure to workers. They are: Acrylonitrile, Arsenic, Asbestos, Benzene, Coke Oven Emissions, Ethylene Oxide, Isocyanates, Lead, Mercury, Silica and Vinyl Chloride. Many of these designated substances are industry-specific, but some of them can be present in building materials and may be present in older buildings.


Identification and Disclosure Prior to Renovation or Demolition


The requirement to complete a designated substance survey prior to completing any renovation or demolition activities at a facility or home is outlined in Part III, Section 30 of the Ontario Occupational Health and Safety Act (OHSA). In addition, it is our experience that an application for a building permit usually requires the submission of environmental information regarding the presence of designated substances or other regulated substances that might be disturbed during the proposed renovation.

The last thing you need on your project are permit delays or unexpected work interruptions. The professionals at Sterling EHS Consulting welcome the opportunity to provide you with your next building survey quotation.
