The In Commerce List is a list of substances that was created when CEPA was enacted in 2000. It was meant to avoid market disruption for substances that were regulated under the Food and Drugs Act.
The initial language of Bill S-5 referred to the In Commerce List, which is the initial list that was created in 2000, of approximately 18,000 substances. The revised language of the amendment proposes to cite a revised list that the government has published in the Canada Gazette, which reduces that list from 18,000 substances to 2,000 substances.
As I explained previously, the consequences of not proceeding with this amendment would be that 18,000 substances that have not been assessed could be added to the domestic substances list, meaning that there would be no premarket assessment done on that large number of substances prior to their commercial activity.
