HFC phase down schedule revised in ODS and Halocarbon Alternatives regulations

The HFC phase down schedule in the regulations has been revised from the draft contained in the Canada Gazette I publication (November 2016), to bring the regulations in line with the terms of Kigali amendment to the Montreal Protocol. This amendment was adopted by the parties to the Protocol in 2016. The baseline HFC consumption quantity for Canada is 19,118,651 tonnes of CO2 equivalent. The consumption reduction schedule contained in the regulation is as follows:

90 per cent in 2019
60 per cent in 2024
30 per cent in 2029
20 per cent in 2034
15 per cent in 2036

The second part of the regulation changes involves establishing limits on global warming potential (GWP) of refrigerants that can be used with industry systems and compliance dates for these limits. The limits and compliance dates are as follows:

1.  Stand-alone medium temp refrigeration systems                        1400 (January 1, 2020)
2.  Stand-alone low temp refrigeration systems                                 1500 (January 1, 2020)
3.  Centralized refrigeration systems                                                    2200 (January 1, 2020)
4.  Condensing Units                                                                                2200 (January 1, 2020)
5.  Chillers                                                                                                     750 (January 1, 2025)
6.  Mobile refrigeration systems                                                            2200 (January 1, 2025)

The GWP limits for systems listed above under numbers 1, 3 and 5 were changed from the draft proposals published by ECCC in Gazette I in November of 2016. In each case, the allowable GWP level has increased.
