Date Activity
January 2023 Anticipated publication of the final screening assessment.
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.


An additional 35 hydrocarbon-based substances were considered to fall within the scope of assessments of hydrocarbon substance and are therefore considered to have previously been addressed under CEPA 1999, and will thus not undergo further assessment at this time. Further details can be found in the screening assessment.
