Before a drug is authorized for sale in Canada, it must be issued a DIN in accordance with the Food and Drug Regulations. Also in accordance with the Food and Drug Regulations, a manufacturer of a drug must annually, before October 1, notify Health Canada that the drug is still on the market and that all the information previously provided pertaining to the drug is correct. The Health Products and Food Branch (HPFB) commits to service delivery standard of 120 calendar days, from the receipt of annual notification, to update the Drug Product Database (DPD).
