Fatality Notice: IHSA has learned of a construction-related fatality in Sudbury involving a construction worker securing a transport trailer load. One workplace fatality is one too many, regardless of the sector, industry, or occupation. Please take a moment to think about those who have died or been injured on the job and re-establish a commitment to the prevention of injuries, illnesses, and fatalities.

Fall Prevention & 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.


Training Requirements

The Ontario Ministry of Labour (MOL) introduced a working at heights (WAH) training program standard and training provider standard to ensure that workers were receiving proper WAH training. Changes were made to Ontario’s health and safety legislation, making WAH training mandatory for workers on a construction project who may be exposed to a fall hazard.

Employers must ensure that their workers are provided with working at heights training that has been approved by the MOL’s Prevention Office. 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 MOL. 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 of the jobsite and develops a fall protection work plan. The supervisor should review the results of the jobsite hazard assessment and the requirements of the fall protection work plan with workers on the site.

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


Job Safety Analysis/Hazard Assessment Template

This will show supervisors where the hazards are and where fall protection is required. Once the hazards have been identified, the supervisor must find the most appropriate solutions to eliminate or control the hazards. These solutions should be included in the fall protection work plan.

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)

Falling from heights continues to be a leading cause of injuries and fatalities in the Ontario construction industry. CPO-approved WAH training is only the first step. Knowing the specific fall hazards on site and how to protect against those hazards is the key to keeping workers safe and reducing the number of fall-related incidents.
