The HFC Phase-Down
Canada's federal regulations under the Ozone-depleting Substances and Halocarbon Alternatives Regulations (ODSHAR) continue phasing down hydrofluorocarbons (HFCs). These are the refrigerants that replaced R-22 — including R-410A, R-404A, and R-134a. If your equipment uses these refrigerants, you need to understand the timeline and your obligations.
Key Compliance Requirements
Leak Inspections Are Mandatory
Systems with 3kg or more of refrigerant must be regularly inspected for leaks. High-charge systems (over 100kg) require annual leak checks by certified technicians with records maintained.
Refrigerant Recovery Required
All refrigerant must be recovered during service — it cannot be vented to atmosphere. This must be done by a TSSA-registered technician using approved recovery equipment.
Record Keeping
Service records must document refrigerant type, quantity added or removed, leak rates, and technician certification numbers. These records must be kept for at least 5 years and available for inspection.
Low-GWP Alternatives
New low-global-warming-potential refrigerants (R-32, R-454B, R-448A, CO2) are required in new equipment installations in many categories. Your next new installation will almost certainly use one of these alternatives.
What This Means for Your Business
If you operate commercial refrigeration equipment, work with a TSSA-certified contractor who maintains proper documentation. Non-compliance can result in significant fines. TCS maintains full TSSA certification and provides compliant service with complete records.
