About
Many refrigerants can harm the ozone layer or add to climate change if they leak into the air. Provincial environmental laws require trained people to handle them. This certificate proves you have that training.
You will need it if you work as an HVAC technician or a refrigeration technician. It covers topics like how refrigerants affect the environment, how to recover and recycle them, how to prevent leaks, and which rules apply to your work. The Heating, Refrigeration and Air Conditioning Institute of Canada (HRAI) offers courses that prepare you for the certificate. The certificate itself is a licence, issued under provincial environmental rules.
How to get it
Check your provincial rules
Find out which agency in your province or territory issues the certificate. Each one sets its own process, so confirm what applies where you plan to work.
Take a training course
Enrol in an approved course, such as those offered through the Heating, Refrigeration and Air Conditioning Institute of Canada (HRAI). Courses are often short and can sometimes be done online or in a classroom.
Study the material
Learn about ozone depletion, refrigerant types, recovery methods and safe handling. Use the course notes and practice questions to prepare.
Pass the exam
Complete the required written exam to show you understand the rules and safe practices.
Receive your certificate
Once you pass, you receive your certificate or licence. Keep it with you on the job, as employers and inspectors may ask to see it.
The exam
The assessment is a written exam. It tests your knowledge of how refrigerants affect the environment, safe recovery and handling, leak prevention and the regulations that apply to your work. Most people study for a short time through a course before sitting it.
Licensed by each province
Each province and territory issues this itself, under its own rules. Each province and territory sets its own rules, and the issuing body, the process and the exact requirements can differ. In general, all of them require certified training to handle refrigerants. Always confirm the details with the regulator where you plan to work, since certificates may not automatically transfer between provinces.
Keeping it
Renewal rules depend on your province or territory. Some certificates do not expire, while others need to be renewed or updated. Check with your provincial regulator and keep your training records so you can show you are current.
