Significant New Activity (SNAc) Notices

When Environment Canada and Health Canada suspect that a Significant New Activity in relation to the substance may result in the substance becoming toxic, a notice is issued to insure that adequate additional information is provided by the notifier or any other proponent who wish to manufacture, import or use of the substance for activities not specified by the notice. The additional information will allow Environment Canada and Health Canada to assess the potential environmental and human health risks associated with the new activities.

This list contains five different flags for substances, however, depending on different situations some flags can be combined together (e.g. T-S, N-S, T-P, etc.). Some of the flags are used to indicate to notifiers that additional notification requirements may be necessary for the substance being manufactured or imported. The flags are:

  • The "S" flag: The letter "S" after a substance identifier indicates that the Significant New Activity (SSNAC) provisions of the Act apply to the substance (see the DSLt of SSNACs).
  • The "S' (prime)" flag: The letter " S' " (`S prime`) after a substance identifier indicates that the Significant New Activity (SSNAC) provisions of the Act apply to substance that was already DSLted on the DSL (see the DSLt of DSL/NDSL updates).
  • The "P" flag: The letter "P" after a substance identifier indicates that the substance was assessed and added to the DSL on the basis that it met the Reduced Regulatory Requirements (RRR) polymer criteria (see section 3.4.1.3 of the Guidelines) and that there was no suspicion of toxicity with this form of the substance. Please note that the purpose of the "P" flag is to indicate that relevant information respecting the flagged polymer must be renotified if anyone, including the original notifier, manufactures or imports the polymer, in Canada, in a form that no longer meets the RRR polymer criteria.
  • The "T" flag: The letter "T" after a substance identifier indicates that the substance was manufactured or imported during the transitional period (e.g. between January 1, 1987, and July 1, 1994).
  • The "N" flag: The letter "N" after a substance identifier indicates that the substance was manufactured or imported after July 1, 1994.
