Understanding the A2L Regulatory Landscape in Canada: A High-Level Introduction

Last week, HRAI introduced a new section in the newsletter – “Refrigerant News” – intended to educate members on the on the A2L transition in Canada.  

This section will be a go-to resource for members seeking information on the regulatory landscape, the latest standards and codes developments, as well as useful information pertaining to the transportation, storage, and safe use and handling of low-GWP refrigerants and pre-charged equipment. 

In today’s section, HRAI will provide members a high-level introduction to the regulatory landscape in Canada.  

As members may recall, from September 18-20, 2022, members and industry partners were in Ottawa for the HRAI Conference and AGM.  Two presentations were delivered that cover key aspects of the regulatory information on the A2L transition in Canada.  

Pushpinder Rana, Mitsubishi Electric Sales Canada Inc. discussed the Kigali Amendment HFC Phasedown Schedules, the current adoption status of low-GWP refrigerants in the United States, the current status of the CSA B52, UL standards, the National Building Code, and next steps and challenges.  

Michel Gauvin, Head, Ozone Layer Protection Programs for Environment and Climate Change Canada, focused specifically on the HFC Phasedown and how Canada will meet its obligations under the Montreal Protocol, including the Kigali Amendment.  

Under the current Ozone-Depleting Substances and Halocarbon Alternatives Regulations, Michel also discussed the HFC phasedown schedule, purpose permits, additional controls on refrigeration products, which will come into effect in 2025, and the ongoing work of the Federal Provincial and Territorial Working Group on Halocarbons.  

We encourage members to review the materials linked here which provide a basic regulatory and technological “lay of the land” on A2Ls.  

Over the coming weeks, HRAI will devote this space to more specific and in-depth reports on the low-GWP regulatory landscape, with reference to both Canada and the United States.
