On December 17, 2021, Canada published the Chemicals Management Plan implementation table for 2021-2024. Under the Canadian Environmental Protection Act, 1999 (CEPA), Canada plans to take the following actions regarding nanomaterials on the Domestic Substances List (DSL): prioritization of substances in commerce according to responses to the CEPA Section 71 Survey and screening

According to the July 7, 2017, issue of the Chemicals Management Plan Progress Report, Health Canada and Environment and Climate Change Canada are in the process of prioritizing nanoscale forms of substances on the Domestic Substances List.  As reported in our July 27, 2015, blog item, Canada conducted a mandatory information-gathering survey under Section

On July 27, 2016, Environment and Climate Change Canada (ECCC) and Health Canada (HC) began a consultation on a proposed prioritization approach for nanoscale forms of substances on the Domestic Substances List (DSL).  Canada will use the proposed approach to:  (1) establish a list of existing nanomaterials in Canada for prioritization; (2) identify how the

Environment Canada and Health Canada have released a February 2015 consultation document entitled Proposed Approach to Address Nanoscale Forms of Substances on the Domestic Substances List.  Environment Canada and Health Canada propose a stepwise approach to address nanoscale forms of substances on the Domestic Substances List (DSL):

  1. Establishment of a list of existing nanomaterials

In a November 21, 2012, Canada Gazette notice, Canada amended the Domestic Substances List (DSL). The amendments include the addition of cellulose, hydrogen sulphate, sodium salt, obtained from sulphuric acid hydrolysis of the bleached pulp, with the substance having the following characteristics:

  • (a) Nominal length of 100 ± 50 nanometres;
  • (b) Cross section dimension less

Environment Canada (EC) recently posted a New Substances Program Advisory Note entitled “Requirements for nanomaterials under the New Substances Notification Regulations (Chemicals and Polymers).” The Advisory Note was signed in June 2007 and states that the Canadian Environmental Protection Act, 1999 (CEPA) and the New Substances Notification Regulations (Chemicals and Polymers) (Regulations) “apply to new nanomaterials just as any other substance, whether a chemical or a polymer.
