Legalization day in Canada has come and gone, but some ambiguities remain.\nCannabis stores across the country, for example, are already running dry. Officials have no estimate as to when demand and supply will eventually reach a balance.\nALSO READ: Montreal Mayor Valérie Plante Is Defying The CAQ And Moving Ahead With The STM Pink Line\nTL;DR Law enforcement agencies are uncertain how to determine whether cannabis in an individuals car was legally or illegally purchased if it is not in its original packaging from the SQDC.\nVia MTLBlog\nBut legal issues persist, too.\nWhile the federal Cannabis Act amended the Criminal Code to provide a new framework for marijuana-related offenses, it was up to individual provincial and municipal governments to perfect that legal code according to their own rules for consumption and distribution.\nQuebec has by far the most strict cannabis laws in the country. Sales are controlled entirely by a government-run corporation, the société québécoise du cannabis (SQDC).\nVia Le Nouvelliste\nThe province also has a zero-tolerance policy for motorists who drive while high.\nBut more unclear are rules about transporting legal cannabis.\nAccording to le Journal de Montréal, law enforcement does not really know how to determine whether marijuana in an individual's car is legally or illegally purchased.\nOfficials are uncertain whether cannabis must be in its original, sealed packing to transport legally.\nPolice told le Journal that it is "too soon" to determine specific enforcement practices. But officers have already made arrests for the transportation of apparantly illegally sourced marijuana only because drivers were unable to prove its legitimacy.\nAccording to the text of Quebec's Cannabis Regulation Act, "in the absence of any evidence to the contrary, the transportation of cannabis without a bill of lading indicating the names and addresses of the shipper and the receiver constitutes proof that it is intended for delivery in Québec" or illegally purchased.\nSo it appears that, in order to transport marijuana, consumers must have a receipt that proves lawful purchase or, if a driver is authorized by the SQDC, specific delivery information.\nThis may face legal challenges. As it stands, it is up to the driver to prove innocence, while the burden of proof should fall on law enforcement.\nUntil this ambiguity is resolved, however, those tranporting cannabis sould always keep a receipt and, ideally, store it in its original packaging.
