Working at Heights Training Ontario: Requirements, Providers & What to Expect
5 min read
Working at Heights (WAH) training became mandatory in Ontario under the Occupational Health and Safety Act in April 2015. If you have workers on construction projects who could be exposed to a fall hazard — whether they work on rooftops, scaffolding, ladders, or elevated platforms — they must complete an approved WAH program. For employers across Ottawa, Russell, Hawkesbury, and Eastern Ontario, here is everything you need to know to stay compliant.
- 1
WAH training is mandatory for all workers on Ontario construction projects where they could be exposed to a fall hazard at any height
- 2
The training must be delivered by a WSIB-approved provider — employer-developed courses do not satisfy the requirement
- 3
The approved program includes theoretical and practical components — workers must demonstrate competency, not just attend
- 4
WAH training does not expire, but refresher training is required when there are significant changes to a worker's role or equipment
- 5
Supervisors must also complete WAH training if they could be exposed to fall hazards
- 6
Completion of WAH training must be documented — workers receive a proof-of-training document they carry on site
- 7
WAH training is separate from — and in addition to — a site-specific fall protection plan, which the employer must still prepare
