Alberta Legal age: 18 Cannabis will be available in licensed stores or online. Alberta is banning public consumption in areas commonly used by children, limiting home-grown to indoors, and setting location restrictions with buffers that keep retail locations for cannabis away from schools, daycares, and community centres. The province doesn’t allow cannabis to be sold in the same place as alcohol, tobacco, or pharmaceuticals. British Columbia Legal age: 19 The Liquor Distribution Branch is British Columbia's wholesale distributor of non-medical cannabis and will also sell online. It'll also be available in private stores, which have been licensed by the Liquor and Cannabis Regulation Branch, which also monitors the recreational marijuana retail sector. Weed can't be smoked or vaped anywhere it's prohibited for tobacco smoking as well. Additionally, it can't be used at schools, playgrounds, sports fields, or places where children commonly gather, and in vehicles. Manitoba Legal age: 19 In Manitoba, consumers can only buy from licensed retailers, they can’t grow it at home or use it in public. Retail stores are selected through competitive bidding processes, selling cannabis supplied by Manitoba Liquor and Lotteries, while the Liquor, Gaming, and Cannabis Authority of Manitoba is the regulator. Stores can't sell both cannabis and alcohol. New Brunswick Legal age: 19 Cannabis New Brunswick, a subsidiary of the New Brunswick Liquor Corporation, will be the only legal provider of cannabis. It will be available online and in stores, where no window displays or other forms of advertising are allowed to be visible outside the stores.

Outdoor plants must be behind a locked enclosure at least 1.52 metres high. Newfoundland and Labrador Legal age: 19 The Newfoundland and Labrador Liquor Corporation is tasked to control the possession, sale, and delivery of cannabis, and to set prices for cannabis products.

Nunavut Legal age: 19 The Nunavut Liquor and Cannabis Commission is selling cannabis online, over the phone, in stores, and through private retailers.

Ontario Legal age: 19 After a government change, and then rules shift, legal cannabis is only available online through the Ontario Cannabis Store. The new Progressive Conservative government has introduced legislation that would launch by April 2019 and permit private retailers to sell if licensed by the Alcohol and Gaming Commission of Ontario. The province would be the exclusive wholesaler to these stores. If it passes, the legislation will forbid smoking or vaping near schools and playgrounds, hospitals and care facilities, public sports fields, enclosed public spaces, and in vehicles.
