Canada’s obligations

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

It requires each state party that has declared possession of chemical weapons and/or chemical weapon production facilities under its jurisdiction and control to destroy them.

Canada’s actions

The Canadian National Authority has many responsibilities, including:

We fulfill our CWC obligations through the following acts and regulations:

No chemical weapon production in Canada

Canada has no chemical weapons or chemical weapon production facilities.

In line with provisions of the CWC, we continue to produce and retain chemicals for domestic riot control purposes. We also maintain facilities and material for use in protective research, such as the development and testing of the following:


Canada made an initial declaration to the OPCW, following the entry into force of the CWC. We also submit to the OPCW:

Chemicals listed on the CWC’s schedules of 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. 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. If verification thresholds are exceeded, Canada and other states parties are also obligated to receive international inspectors from the OPCW to verify declarations submitted under Article VI. 

OPCW inspectors may also come to Canada to verify the destruction of chemical weapons found and reported under Article IV. The CWC also provides for challenge inspections to investigate suspected violations of its obligations.
