Arlington, Va. – The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) today announced the release of a new interactive map of Canada which lists where the province and local building codes have been updated to allow equipment using A2L refrigerants. This Canadian map follows the successful 2024 launch of a U.S. version.

AHRI’s interactive maps are valuable tools for original equipment manufacturers, HVACR contractors, authorities having jurisdiction, building inspectors, fire marshals, code or other officials, and lawmakers seeking information about applicable air conditioning, refrigeration, and warehousing codes, legislation, and standards currently referenced.

"The response to AHRI’s U.S. interactive map was overwhelmingly positive, so we were confident that providing this resource to our Canadian counterparts would be helpful to all stakeholders. AHRI’s interactive maps are the only comprehensive sources for information on building codes and legislation available, and will be updated as codes and laws change,” said Tom Deary, AHRI Senior Director of Codes.

The Canadian refrigerant building code map was developed in consultation with the Heating, Refrigeration, and Air Conditioning Institute of Canada (HRAI). Access the Canadian map here and see the U.S. version here.
