Working at Heights Training: Construction Projects

Safe At Work Ontario

Employers in Ontario must ensure that workers on construction projects who may use certain methods of fall protection successfully complete 'working at heights' training that meets training program and provider standards established by the Chief Prevention Officer (CPO).

The Occupational Health and Safety Awareness and Training Regulation (Ontario Regulation 297/13) under the Occupational Health and Safety Act (OHSA) sets out the mandatory working at heights training requirements. The working at heights training is valid for three years from the date the worker completes an approved training program delivered by an approved training provider.

In addition to these requirements, employers continue to have a duty under subsection 26.2 (1) of O. Reg. 213/91 (Construction Projects) to ensure that workers who may use a fall protection system are adequately trained on the use of the system, and are given adequate oral and written instructions by a competent person.

The working at heights training requirements apply to workers who are required under O. Reg. 213/91 (Construction Projects) to use any of the following methods of fall protection:

  • a travel restraint system;
  • a fall restricting system;
  • a fall arrest system;
  • a safety net;
  • a work belt;
  • a safety belt.


Employers with workers who are required by O. Reg. 213/91 (Construction Projects) to use any of the fall protection methods listed above must do the following:
