Can I Bring Air horn on a Plane to Canada?

According to CATSA guidelines, air horns that use aerosol, such as bear horns, are permitted in carry-on when the container is <100 mL (3.4 oz) or less and placed in a 1L clear bag. With air carrier approval, each passenger can bring a maximum limit of 500 mL or 500 g per container, with a total net quantity not exceeding 2 L or 2 kg in their checked baggage. Release valve on aerosols must be protected by a cap or other suitable means to prevent accidental release of the contents.
