Date Activity
April 20, 2024 Publication of the final assessment. The related notice was published in the Canada Gazette, Part I: vol. 158, No. 16.
January 8, 2022 Publication and start of 60-day public comment period on the draft screening assessment. The related notice was published in the Canada Gazette, Part I: Vol. 156, No. 2.


The assessment also identifies an additional 35 hydrocarbon-based substances for which risk assessment activities are considered to have already taken place under CEPA. Based on their composition, physical-chemical properties and reported uses, these additional 35 substances were considered to fall within hydrocarbon-based substance groups that have previously been addressed under CEPA, and will thus not undergo further assessment at this time. Further details can be found in the assessment.
