2. Health Canada advises that discretion may be required in applying the three-month criteria in unusual circumstances; for example, long-term visitors to isolated locations, long-term visitors where language or other barriers may impede establishing an association with a Canadian physician, persons returning from countries which dispense drugs in trade packages.
5. The Food and Drug Regulations restrict the importation of prescription drugs listed in Schedule F, Part I, or Schedule F, Part II, that are not for veterinary use. Importation is restricted to a practitioner, a drug manufacturer, a wholesale druggist, a registered pharmacist, or a resident of a foreign country while a visitor in Canada. Individuals, including Canadian residents, arriving in Canada from abroad are usually permitted to import a single-treatment size or a three-month supply of a Schedule F drug for their personal use. The drug must be packaged in pharmacy or hospital dispensed packaging. Any other importations of prescription drugs will be detained by Revenue Canada and referred to Health Canada.
