Consultation Notice

Proposed Risk Management Strategy for N-Nitrosodimethylamine (NDMA)

The purpose of this notice is to invite you to participate in consultations for the proposed risk management strategy for N-Nitrosodimethylamine (NDMA) under the Canadian Environmental Protection Act, 1999 (CEPA 1999).

A final decision on the assessment of NDMA was published in the Canada Gazette on April 13, 2002. This report concluded that NDMA is considered to be entering the environment in a quantity or concentration or under conditions that constitute or may constitute a danger in Canada to human life or health. Based on this conclusion, NDMA was added to Schedule 1 (List of Toxic Substances) of CEPA 1999 on May 15, 2003.

There are no industrial or commercial uses of NDMA in Canada, nor is the substance manufactured or imported into Canada. Thus, it was identified that a risk management instrument should be put in place to prevent the manufacture, use, sale, offer for sale and import of NDMA in Canada. On March 9, 2005, following consultations, NDMA was added to the Prohibition of Certain Toxic Substances Regulations, 2005, incorporating an exemption for the incidental presence of NDMA.

Environment Canada has developed a proposed risk management strategy for NDMA. In addition to identifying the Prohibition of Certain Toxic Substances Regulations, 2005 as an appropriate risk management measure, the strategy outlines additional actions to be taken to address the risks posed by NDMA.

At this time, all stakeholders are invited to provide written comments regarding the proposed risk management strategy for NDMA. Any comments should be addressed to Manon Drake, and must be received no later than October 27, 2006.

If you have any questions about this process, please contact Manon Drake from the Chemicals Sector Division by phone at (819) 994-5927 or by e-mail at

Yours sincerely,
