Working at heights training in Ontario is more than just a safety course—it's a life-saving requirement. For anyone employed in construction, roofing, maintenance, or any job that involves elevation, undergoing this regulated training is mandatory under Ontario law. Whether you’re a new hire or renewing your certification, this guide covers everything you need to know.
What is Working at Heights Training?
Working at heights training is a standardized safety training program required by Ontario's Ministry of Labour, Immigration, Training and Skills Development (MLITSD). It teaches workers how to recognize and prevent fall hazards, properly use fall protection equipment, and safely work in elevated environments.
The training is designed for individuals who work at heights of more than 3 metres (10 feet) where there is a risk of falling, including tasks on ladders, scaffolding, roofs, or platforms.
Why is Working at Heights Training Mandatory in Ontario?
Falls are one of the leading causes of workplace injuries and fatalities in Ontario. To reduce these incidents, the provincial government has enforced strict legislation under the Occupational Health and Safety Act (OHSA). According to Ontario regulations, workers on construction sites must complete a Working at Heights (WAH) training program that is approved by the Chief Prevention Officer (CPO).
By ensuring workers receive proper instruction and hands-on experience, the program reduces risk and improves compliance with workplace safety standards.
Who Needs Working at Heights Training in Ontario?
You must complete this training if:
-
You work in construction or related trades
-
Your job involves working on ladders, scaffolds, roofs, or elevated work platforms
-
You use fall protection systems such as harnesses, lanyards, or guardrails
-
Your employer requires proof of training for insurance or legal compliance
Even supervisors and managers overseeing work at height may be required to complete the course to ensure site-wide safety.

An approved working at heights training in Ontario typically covers:
1. Theoretical Training

Certification Validity and Renewal

Refresher courses are shorter, focusing on updated standards and reinforcing practical skills. It’s essential to keep your certification up to date, as employers must verify your credentials before allowing you on elevated job sites.
Online vs In-Person Training: What’s Better?
Ontario mandates that working at heights training includes practical, hands-on instruction, which means a portion of the course must be completed in person. Some training providers offer blended options, where the theoretical components are completed online and the practical portion is done on-site.
Pros of Blended Learning:
-
Flexible scheduling
-
Reduced time in the classroom

Pros of In-Person Training:
-
Direct interaction with instructors
-
Real-time feedback on technique

Choose the format that best suits your learning style and availability, as long as the provider is CPO-approved.
