Medical marijuana is not a legal drug in Canada. It is an illicit (illegal) substance and Health Canada's current accessibility policy hasn't changed that fact. Marijuana has not been designated a prescription medication or medication of any kind. Not only does it not currently have a DIN, it looks like it will not have one any time soon. According to the Medical Use of Marijuana section on Health Canada's website, DIN's can only be issued after Health Canada scientists have assessed a drug's safety, efficacy and quality in order to be sure it meets Regulations and the requirements of the Food and Drug Act.
