The Canadian National Authority (Chemical Weapons Convention)

The implementation of the Chemical Weapons Convention (CWC) is carried out 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 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.  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 protective clothing, equipment and medical counter-measures.

Following Entry into Force (EIF) of the Convention, Canada made an Initial Declaration to the Organization for the Prohibition of Chemical Weapons (OPCW).  Canada annually submits to the OPCW 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/Old Chemical Weapons pursuant to Article IV, paragraph 9.

Canada and other States Party are also obligated to receive international inspectors from the OPCW to verify declarations submitted under Article VI if the verification thresholds are exceeded.  OPCW inspectors may also come to Canada to verify the destruction of CW/OCW found and reported under Article IV. The CWC also provides for Challenge Inspections to investigate suspected violations of its obligations.

Scheduled chemicals and 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.  These Declarations form the basis for on-site inspections.
