RE:RE:RE:RE:Q5. When will adult Canadians be able to legally purchase "In those provinces or territories that have yet to authorize retailers, adults would be able to purchase cannabis directly from a federally licenced producer by ordering online with secure delivery at home by mail."
This means if they don't have a retail distribution in place by July 2018, then rec mail order would be allowed. This could just be in the interim. It is not clear if mail order will happen if the meet the deadline.
More clarification would be needed on this, but you can't assume it means mail order will happen. It sounds more like a stop-gap measure with how it's written.
