Why Working at Heights Training is Mandatory in Ontario

In Ontario, the Construction Regulation (O. Reg. 213/91) mandates that workers using fall protection systems must receive proper training that complies with the Working at Heights training standards under O. Reg. 297/13. This training ensures workers can safely perform tasks at elevated levels by understanding:

  • Their rights and responsibilities when working at heights
  • How to properly inspect, wear, and maintain fall protection equipment
  • The hazards associated with working at heights and how to control them

Failing to comply with these regulations can result in fines, workplace accidents, or even fatalities, making proper training essential for both employers and workers.

How Long is Working at Heights Training Valid?

The initial Working at Heights certification is valid for three years from the completion date. After this period, workers must complete a refresher course to maintain their certification. The refresher training reinforces key concepts, including:

  • A review of fall hazards and controls
  • Hands-on practice with fall protection equipment
  • Updates on regulatory changes

Recent Updates on Working at Heights Training Expiry

The Ministry of Labour, Training and Skills Development (MLTSD) has extended the validity period for workers who completed their training between February and August 2017. Their certifications are now valid until the end of 2021. However, workers who took their training before February 2017 or after August 2017, must complete a Working at Heights Refresher course to stay compliant.
