Does the legislation by Health Canada mean that marijuana is a legal substance?

No. Marijuana is categorized as a controlled substance. It is not legal to grow or possess marijuana except with legal permission by Health Canada. The Marihuana Medical Access Regulations allow access to marijuana to people who are suffering from grave and debilitating illnesses. It is important to note that the Regulations deal exclusively with the medical use of marijuana. They do not address the issue of legalizing marijuana.
