Fall Prevention and Working at Heights

Fall Prevention and Working at Heights

Falls are a major cause of injury and death in Ontario workplaces. The vast majority of these incidents are falls from heights—even though the height may be no more than two or three metres.

This topic page provides helpful information about working at heights training and ways to prevent fall injuries and fatalities.


Mandatory Training Requirements

Working at heights (WAH) training is mandatory for workers who may use a method of fall protection to protect themselves from a fall hazard. Employers must ensure that their workers are provided with working at heights training that has been approved by the Prevention Office of the Ministry of Labour, Training, and Skills Development (MLTSD). A WAH refresher course must be taken every three years to maintain this training.

IHSA was one of the first WAH training providers to be approved by the MLTSD. We offer the following courses:


In addition, employers must ensure that workers are given site-specific training and proper oral and written instructions. This includes making them aware of fall hazards at the project and providing instruction on the particular equipment they will be using.

To meet this requirement, employers should ensure that the site supervisor conducts a hazard assessment or job safety analysis (JSA) of the jobsite and develops a fall protection work plan. The supervisor should review the results of the assessment and the requirements of the fall protection work plan with workers on the site.

If workers use a fall arrest system, employers must develop procedures for rescuing a suspended worker. They can also put up posters and warning signs around the worksite and distribute stickers to workers to remind them about fall hazards on site.

We have provided the following resources to help employers meet their site-specific training obligations:

Sample Fall Rescue Procedures

Before any worker uses a fall arrest system on a project, the employer is legally required to develop written procedures for rescuing someone whose fall has been arrested. These rescue procedures should also be reviewed with the workers and must be posted in a conspicuous place at the project. We have provided some sample fall rescue procedures that employers can customize to meet their needs.

Health and Safety Advisory: Working at Heights - Site-Specific Training (W254)

All Ontario workers on a construction project who may use a method of fall protection to protect themselves from a fall hazard must receive approved working at heights (WAH) training. However, an important part of WAH training that is often overlooked is the requirement for the employer to provide site-specific WAH training. This advisory contains helpful information on providing site-specific WAH training to workers. 2 pages. Revised August 2020.
