The Canadian National Authority (Chemical Weapons Convention)

Contact Us

The Canadian National Authority is located at the Department of Foreign Affairs, Trade and Development. It is mandated to implement the Chemical Weapons Convention Implementation Act, while minimizing its impact on Canadian industry, research, and other institutions. This implies that every industry, laboratory, university, or any other institution in Canada which produces, processes, consumes, exports, or imports any of the scheduled chemicals in the Chemical Weapons Convention (CWC) is potentially required to make Annual Declarations.   Canada, as represented by its National Authority, must deliver its Past Activities Declaration, covering the previous calendar year to the OPCW by the end of March each year.  Consequently, Canadians affected by the CWC must provide their data by the end of February.  Anticipated Activities Declarations for the three lists of scheduled chemicals are also required and must be submitted to the National Authority by 15 September of each year.
