If you work in construction or any job that involves fall protection equipment, Working at Heights (WAH) training isn’t optional — it’s the law. Ontario’s Ministry of Labour, Immigration, Training and Skills Development (MLITSD) sets strict safety standards to prevent workplace injuries and fatalities related to falls.

Before stepping onto a site, every worker using fall protection must complete an approved Working at Heights training program delivered by an approved provider. Employers are responsible for verifying and maintaining training records, and refresher courses are required every three years to stay compliant.

Below, we’ll break down the key Ontario laws and regulations you need to know about Working at Heights training — including certification requirements, employer responsibilities, course components, and renewal timelines.

• Law #1: Ontario requires that anyone working on a construction project who uses fall protection equipment must take working at heights training.
• Law #2: Your employer is responsible for getting a record of training from your working at heights training provider.

There are, however, limited exemptions if you are a worker who is directly employed by an automobile manufacturer or assembler.

Law #2: Employers Must Keep a Record of Working at Heights Training

Working at Heights Theory

The theory component of ACUTE’s Working at Heights training takes approximately three hours and provides a strong foundation in Ontario’s legal requirements and safe practices for preventing falls.

This in-class session is led by experienced, Chief Prevention Officer (CPO)–approved instructors and follows the Ministry of Labour, Immigration, Training and Skills Development (MLITSD) Working at Heights Training Program Standard.

At the end of this module, you’ll complete a written evaluation to ensure full comprehension of all safety principles discussed.

Working at Heights Practical Component (Approx. 3.5 Hours)

The practical session allows participants to apply what they’ve learned in a controlled, hands-on environment. This portion focuses on safely using, inspecting, and maintaining fall-protection systems and equipment.

Topics Covered:

• A-B-C components (anchorage, body support, connecting devices): selection, inspection, and use

• Harness fitting, lanyard inspection, and evaluation

• Rescue plans — components, purpose, and implementation

• Identifying and using safe anchor points

Participants complete both a written and a practical evaluation to demonstrate competence and earn their certificate of completion.
