The Difference Between Full Certification and Refresher Training

When Can You Take a Refresher Course?
To be eligible for a refresher, you must complete it by the expiration of your original certification or during the renewal period allowed by your training provider and any provincial regulations.
Refresher courses are typically faster than taking the entire training course again because they are focused on reviewing essential concepts regarding fall protection, updating any new safety issues, and identifying practical hazards, among other things.
Employers should plan to have refresher courses scheduled early enough before expiration to prevent compliance issues and work interruptions.
What Happens If Your Certification Fully Expires?
If an employee misses the certification renewal date, their current certification will lose eligibility for refresher training. As a result, they may be required to complete the full working at heights programme again.
This means:

- Paying the cost of the full course
- Delay in getting back to working on regulated projects.
- Additional administrative burden for the employer.
It is therefore recommended the worker tracks certification dates and prepares to renew their certification a few months before it expires.
