On January 8, 2011, Environment Canada published a proposal to add Significant New Activity (“SNAc”) flags to three substances that are currently on the Domestic Substances List. These substances are: 1H-Indene, 2, 3-dihydro-1,1,3,3,5-pentamethyl-4,6-dinitro-, CAS No. 116-66-5, Ethanamine, N-ethyl-N-hydroxy-, reaction products with hexamethylcyclotrisiloxane, silica and 1,1,1-trimethyl-N-(trimethylsilyl)silanamine, CAS No. 68583-58-4 and Pyridine, 2-[3-(3-chlorophenyl) propyl]-, CAS No. 101200-53-7. The proposal was open for comment from January 8 – March 8, 2011. The SNAc flag would, once added to the DSL, prohibit any person from using, manufacturing or importing more than 100 kg of the substance unless specified information is first provided, including the information set out in Schedule 6 to the New Substance Notification Regulations (Chemicals and Polymers) (“NSN Regulations”), and an assessment period of 90 days has expired.

On January 15, 2011, Environment Canada published a proposal to add at SNAc flag to the Domestic Substances List in relation to Nickel, bis[2,3-bis(hydroxyimino)-N-(2-methoxyphenyl)butanamidato]. Specified information, including but not limited to information from Schedules 4-6 of the NSN Regulations, must be provided to Environment Canada 90 days prior to the use, import or manufacture of 100 kgs of the substance.

On January 22, 2011, Environment Canada published a proposal to add SNAc flags to the Domestic Substances List in relation to five additional substances: Thiourea (CAS No. 62-56-6); Oxirane, chloromethyl- (CAS No. 106-89-8); Phenol, 2,4,6-tris(1,1-dimethylethyl)-, CAS No. 732-26-3); C.I. Pigment Yellow 34 (CAS No. 1344-37-2); and C.I. Pigment Red 104 (CAS No. 12656-85-8). The proposal was open for comment from January 22 - March 22, 2011. Specified information must be submitted 180 days prior to the use, import or manufacture of these substances. Specific uses of the substances are exempt.

On January 12, 2011, Environment Canada amended the Domestic Substances List to add a SNAc flag to the substance Resin acids and Rosin acids, fumarated, barium salts, CAS No. 124751-15-1. The SNAc flag requires submission of the information set out in Schedule 6, 90 days prior to the threshold of 100 kg being reached.
