While we are not yet finished with Phase 3 of the CMP there is much activity related to preparing for a possible Phase 4, which is being referred to as Post-2020. Since the Parliamentary Committee Review of CEPA as it relates to chemicals management has concluded and Parliament indicated that it would not proceed on amending CEPA in this session, there has been ongoing work by officials to address some of the key issues raised in the Committee’s report. These include the more controversial issues that have always been of concern to industry in the assessment of chemicals, the determination of possible toxic designation, and related risk management measures. These include informed substitution or alternative assessment, assessment through the lens of vulnerable populations, endocrine disruptors being at the centre of assessments, applying the precautionary principle to every assessment, and lifting the lid of confidential business information after a period of time. These and other approaches, if not handled properly, could severely restrict the use or concentration levels in a wide spectrum of substances used in an even wider spectrum of products. CEPA has not been amended, but could such approaches undertaken via existing policies and programs amount to a de facto amendment to CEPA? That is what a large coalition of environmental NGOs are hoping. This session will delve into the implications of this issue and how CPCA is engaged.
