2011: R. v. Mernagh (Ontario Superior Court)
On April 12, 2011, Justice Donald Taliano found that Canada's Marijuana Medical Access Regulations (MMAR) and "the prohibitions against the possession and production of cannabis (marijuana) contained in sections 4 and 7 respectively of the Controlled Drugs and Substances Act" are "constitutionally invalid and of no force and effect". The government was given 90 days (until July 11) to fill the void in those sections, or the possession and cultivation of Marijuana would become legal in all of Canada. This includes the non-medical use of the drug.
The mid-July deadline was extended when federal government lawyers argued that current cannabis laws and regulations should stay in place until Ontarioâ??s highest court could hear the appeal which has been scheduled for March 5 and 6, 2012. In granting the deadline extension, the Court of Appeal noted that â??The practical effect of the decision if the suspension were permitted to expire on July 14 would be to legalize marijuana production in Ontario, if not across Canada.â?? 
So what are the chances? i really need this for my chronic injuries.
