Workers participate in WHSC Working at Heights training in Ontario


Falls from heights are the leading cause of traumatic worker deaths and critical injuries in construction. To help stop these tragedies, Ontario regulation requires employers to ensure all construction workers in their employ complete a Working at Heights (WAH) training program, approved by the Ministry of Labour's Chief Prevention Officer, and before working at heights and using a fall restricting system, fall arrest system, safety net, work belt or safety belt.

This initial WAH training is valid for three years from the date of successful completion of an approved program. For continued compliance, employers must ensure workers they employ complete an approved WAH refresher program every three years.
The WHSC can help meet these training requirements. We were among the first providers to gain approval to deliver both the initial WAH training and the WAH refresher training. With qualified instructors located throughout the province, we can help you get into compliance fast. Beyond the minimum compliance requirements, our programs are designed to ensure critical learning takes place.  Further still, we maintain training records for you.
