Date Activity
December 12, 2020 Publication of the final screening assessment. The related notice was published in the Canada Gazette, Part I: Vol. 154, No. 50.
April 6, 2019 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. 153, No. 14.


These 8 substances were previously evaluated under the second phase of polymer rapid screening, but were classified as requiring further assessment due to their potential human health risk on the basis of structural alerts and/or uses associated with significant consumer exposure.
