Bear Spray

CBSA Memorandum D-19-13-2 wrote:
(c) Any other spray designed to be used against humans (e.g., “pepper spray”) – These are chemical agents, often packaged in the form of aerosol sprays, made with the active ingredient capsaicin. Pepper spray is also known as OC (oleoresin capsicum) spray or OC gas. It is used to cause temporary incapacitation through irritation of eyes, skin, mucous membranes, and/or respiratory system, sometimes causing temporary blindness. In addition, some devices labelled as “pepper spray” may also contain Mace and/or tear gas.

Exception: Aerosol or similar dispensers that contain substances capable of repelling or subduing animals (e.g. dog or bear repellent) are not considered prohibited weapons if: (i) the label of the container indicates specifically that it is for use against animals only; and (ii) the provisions of the Pest Control Products Act are met. (iii) In order for a device or dispenser to be considered to meet the above criteria, it must be apparent that the device was designed exclusively for the control or use against animals. The manufacturer’s label and specifications will be deemed as the design of the product. The misuse of these or any other similar device may nonetheless be punishable under other laws. (iv) Please note that there is no minimum quantity or capacity requirements (in terms of grams or milliliters) in making the determination with respect to animal repellents.
