Asbestos Hazards

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

As of November 1, 2007, workers and supervisors who perform Type-3 asbestos abatement work are required to be certified to do their 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:


Regulation 278/05: Asbestos on Construction Projects

A new asbestos regulation was introduced in November 2005. Regulation 278/05, Designated Substance-Asbestos on Construction Projects and in Buildings and Repair Operations, replaced the old Regulation 838. The major changes include:

1. A definition for asbestos-containing material (ACM),
2. A reclassification of certain ACM operations,
3. A new training program for asbestos abatement workers and supervisors,
4. An approval process for introducing new procedures providing equal protection, and
5. New and updated requirements for:

  • bulk sample analysis,
  • respiratory protection,
  • glove bag operations,
  • the use of negative air pressure to prevent dust leakage, and
  • air clearance sampling, cleaning and testing.

You can access the online version of the asbestos regulation or download the print version below. As well, there is a link to the Ministry of Labour (MOL) website which contains a guide to the asbestos regulation.

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).


Asbestos Interactive Tool

The Asbestos Interactive Tool is an excel file that you can run online or download to your computer. The tool presents you with a list of asbestos removal operations. Just click on the option that applies to the type of asbestos removal you will be performing and the tool will determine the type of respirator required to do the job safely.
