Working at Heights!


Pursuant to the authority under subsection 7.2(1) of the Occupational Health and Safety Act (OHSA), NATT Safety Services has been approved by the Chief Prevention Officer as a training provider to deliver the approved working at heights program – Working at Heights – Fundamentals of Fall Prevention (WAH) that has been approved pursuant to subsection 7.1(1) of the OHSA. The approval will be posted on the MOL website as an approved vendor.

We aim to create and maintain a safe environment for all of our employees, customers and contractors.  Our goal is to be the leader in safety training, education and safety services by employing and training the most capable people in the field across the Province of Ontario.

“Safety is our #1 priority.  In keeping in line with our business structure of offering the mobility of our certified trainers across the Province, we are excited to offer (WAH) as part of our specialty training services, on location or in our state-of-the-art training centre in Lively, Ontario.”

Mark Arnold, General Manager, NATT Safety Services. 


The working at heights training requirements set out in O. Reg. 213/91 came into force on April 1, 2015, requiring that employers ensure that workers on construction projects successfully complete a working at heights training program approved by the Chief Prevention Officer (CPO) and delivered by a CPO-approved training provider before they can use a method of fall protection.


Working at heights training is valid for three (3) years from the date of successful completion of an approved program. All learners who wish to maintain the validity of their working at heights training past this three year period need to successfully complete refresher training.


Working at heights refresher training reinforces key learning outcomes for workers who are exposed to the danger of falling from heights on construction projects. All workers who work at heights on construction projects must be able to demonstrate their knowledge of the correct use of fall protection equipment.


The refresher training also will update learners on any legislative, regulatory or equipment (technological) changes which may impact working at heights in construction.


Working at heights refresher training is the practical module of the working at heights training program (section 9.2 of the Working at Heights Training Program Standard). The minimum duration for training delivery of the practical module is three and a half (3.5) hours.


The practical module covers the following topics:

  • Barriers and other fixed equipment
  • Personal fall protection equipment (travel restraint, fall restricting, fall arrest systems)
  • Anchor points
  • Work positioning systems, work access and platforms
  • Rescue planning.


It includes a hands-on demonstration of equipment and procedures to ensure learners can successfully inspect and use the required fall protection equipment. There is a written test.


“Leadership and learning are indispensable to each other. No matter who we are or where we live, we all share a basic concern for the safety and well-being of our people. Their welfare is the most telling measure of our success - and their potential is the most promising element of its future. It is up to us - all of us - to safeguard that future.”

Jennifer Roy, Divisional Manager, Health & Safety Officer, NATT Safety Services


We look forward to providing this extension of safety services to our clients in Northern Ontario and within the Province of Ontario.
