Fatality Notice: IHSA has learned of two separate fatalities this week: One involved a millwright and the other a utility employee. One workplace fatality in any year is one too many, regardless of the sector, industry, or occupation. Please pause all work for a safety moment and re-establish a commitment to the prevention of injuries, illnesses, and fatalities.

Asbestos Hazards

Asbestos exposure

Asbestos exposure can cause a number of deadly diseases and they can take a long time to develop—up to 40 years. Asbestos-related diseases are the #1 cause of work-related death for people who have worked in Ontario construction. If you work in the building trades, then you have probably been exposed to asbestos.


Mandatory Asbestos Certification

Workers and supervisors who perform Type-3 asbestos abatement work are required to be certified to do this type of work. Certification is not required for:

  • Workers in Type 1 or Type 2 operations
  • Workers entering Type 1, Type 2, or Type 3 work areas to perform work not related to the asbestos operation.

Training and Certification Courses

We offer two asbestos abatement certification programs: one for workers and one for supervisors, as well as an instructor workshop. Before becoming a certified asbestos abatement supervisor you must be certified as an asbestos abatement worker.


The workers that do not require certification are, however, required to have asbestos awareness training. We offer the following courses:

Asbestos Chart

The Asbestos Chart helps you determine the "Type" of your asbestos operation as well as the respirator you require. It is intended to be used in conjunction with IHSA's data sheet Asbestos: Controls for Construction, Renovation, Demolition (DS037).
