Drugs

The list of drugs specifically authorized for sale in Canada for use in aquaculture can be found on Health Canada’s website:

• List of Veterinary Drugs that are Authorized for Sale by Health Canada for Use in Food-Producing Aquatic Animals
• List of Veterinary Drugs that are Authorized for Sale by Health Canada for use in Hatchery Eggs (Aquaculture)

More details on use may be found within Health Canada’s Drug database

A number of products, like erythromycin and ivermectin, are not listed explicitly for aquaculture but are used legally according to Emergency Drug Registrations (EDR) or when prescribed by a registered veterinarian for extra-label use. Aquaculture facilities and veterinarians in Canada may also access veterinary drugs either through Health Canada’s Emergency Drug Release program or an Experimental Study Certificate. The Emergency Drug Release program considers requests from veterinarians for access to drugs for veterinary use that are unavailable for sale in Canada and that are for the purposes of diagnosing or treating a medical emergency in an animal (or group of animals) under their care. An Experimental Study Certificate may be issued to an investigator for the purposes of conducting an experimental study in animals with a new drug. See Health Canada’s Policy on Extra-Label Drug Use (ELDU) in food producing animals for more information.
