for destruction, reclamation, feedstock or laboratory use. Table 2
provides permitted uses for methyl bromide. Table 3 of Schedule
1 gives the ozone-depleting potential of various hydrochlorofluorocarbons
(HCFCs). Canada prohibits the import or sale of
HCFCs without a permit. Permits to import and sell HCFCs may
only be obtained for specific purposes such as destruction, use
in feedstock or for laboratory or analytical use. It is prohibited to
import or sell a pressurized container that contains 2kg (4.4 lbs.)
or less of an HCFC set out in Table 3 of Schedule 1. Additionally,
as of Jan. 1, 2020, it will be prohibited to manufacture a product
containing an HCFC set out in Table 3 of Schedule 1. However,
this prohibition doesn’t apply to some specific product types,
such as certain mold release agents, lubricants and rigid foam
products.
Table 4 of Schedule 1 outlines various HFCs and their GWP values.
It is prohibited to import an HFC from Table 4 into Canada
without a permit. Permits are issued for destruction or use as feedstock
and may also be issued to import an HFC that is recovered,
recycled or reclaimed. Additionally, an annual consumption allowance
may be granted for an HFC if it is intended for a purpose
for which a more harmful ozone depleting substance in Tables 1–3
of Schedule 1 has been used in Canada.
Effective Jan. 1, 2019, pressurized containers containing
2kg (4.4 lbs.) or less of an HFC used as a propellant that has a
GWP greater than 150 are prohibited for import and manufacture.
The three most commonly used HFCs—HFC-125, HFC-
134a and HFC-245fa—fall into this category.
These propellants are now effectively banned in aerosol products
in Canada except for use in certain product types such as
mold release agents and products used to clean, dust or prevent
corrosion on electronic components, photographic negatives
and semiconductor chips.
Due to their lower GWP, aerosols containing HFC-152 and
HFC-152a may still be imported and manufactured in Canada.
If you are currently using HFCs as propellants in your Canadian
aerosol products, it is essential to ensure that you are complying with
the Ozone-Depleting Substances & Halocarbon Alternatives Regulation
and Amendments. Even if you are not selling into Canada, we
encourage you to examine the global warming and ozone depleting
potential of your products, as there may be a more environmentally
friendly alternative that can do the same job. Spray
While HFCs are not manufactured in Canada, they are imported in bulk
and found in a variety of products.
