The Food and Drugs Act prohibits most direct-to-consumer advertising of prescription medications: all direct-to-consumer advertising of drugs was forbidden until 1978, when Health Canada began to allow ads containing names, quantities, and prices only, so that pharmacies could display their prices for comparison purposes. In 2000, Health Canada adopted an interpretation of this law allowing for the aforementioned "reminder" and "help-seeking" advertisements, although U.S.-style "full product ads" that mention the purpose of a prescription remain prohibited. Later that year, Health Canada ruled that a pairing of similarly-themed reminder and help-seeking commercials ran afoul of the regulations, as their combination constituted a full product ad.
