Canadian National Authority

The Chemical Weapons Convention (CWC) is implemented in Canada by the Canadian National Authority, which also serves as the focal point for effective liaison with the Organisation for the Prohibition of Chemical Weapons (OPCW) and other States Parties. The Canadian National Authority is located at Global Affairs Canada.

Canada’s obligations

The Convention prohibits the development production, acquisition, stockpiling, transfer and use of chemical weapons (Article I).

It requires each State Party which has declared possession to destroy chemical weapons and chemical weapon production facilities under its jurisdiction and control.

No chemical weapon production in Canada

Canada has no chemical weapons or chemical weapon production facilities. In line with provisions of the Convention, Canada can continue to produce and retain chemicals for domestic riot control purposes. Canada can also maintain facilities and material for use in protective research, such as the development and testing of:


Following Entry into Force of the Convention, Canada made an Initial Declaration to the OPCW. Canada also submits to the OPCW annual Declarations of Anticipated and Past Activities pursuant to Article VI (industrial facilities), Declarations of national protective programs pursuant to Article X, paragraph 4, and Destruction Reports of discovered Chemical Weapons (CW)/Old Chemical Weapons (OCW) pursuant to Article IV, paragraph 9.

Chemicals listed on the CWC’s Schedules, Discrete Organic Chemicals (DOCs), and related facilities are subject to data monitoring and on-site inspections. Companies or organisations whose business involves these chemicals must make appropriate declarations to the Canadian National Authority. In turn, the National Authority is responsible for making national Declarations to the OPCW. Declarations also include information on the export and import of Scheduled Chemicals.


The Declarations provided by Canada to the OPCW form the basis for on-site inspections. Canada and other States Parties are also obligated to receive international inspectors from the OPCW to verify declarations submitted under Article VI if verification thresholds are exceeded. 

OPCW inspectors may also come to Canada to verify the destruction of chemical weapons or old chemical weapons (those made before January 1, 1946) found and reported under Article IV. The CWC also provides for Challenge Inspections to investigate suspected violations of its obligations.
