  • Issued: June 13, 2013
  • Content last reviewed: June 2013

The herbicide known as 2,4,5-T was used in the 1950s, 60s and 70s for weed and brush control by sectors such as forestry, transportation and agricultural sectors (for non-crop land). 2,4,5-T was used across the province in various locations, including hydro rights-of-way, along roadsides and highways, and for forestry activities. Ontario suspended the use of 2,4,5-T in 1979 and banned it in 1980. The federal government deregistered the product in 1985.

The Ontario Minister of Natural Resources established the Ontario Independent Fact-Finding Panel on Herbicide 2,4,5-T to determine where, when and how 2,4,5-T herbicide was used in Ontario by government ministries and agencies, and whether exposure may have potential health impacts. The report presents the findings of the panel’s work.

If you have concerns about potential past workplace exposure to 2,4,5-T, please call the Workplace Safety and Insurance Board (WSIB) at 1-800-387-0750. Information is also available on the WSIB website.The WSIB is committed to working with Ontarians who may have been exposed to herbicides in the workplace and contracted a work-related illness. WSIB will also be reviewing the report.

Anyone with health concerns related to possible 2,4,5-T exposure is encouraged to consult with their doctor.
