I get the sense from the release that there will be an entirely different set of private pot stores, so you could in theory have a pot shop next to a liquor store. It hasn't been said that existing private liquor stores will have first dibs per se on marijuana sales. Government has only said that the retail model will be similar to alcohol, so just that private and public retailers will both exist. Heck, the BC Government could go ahead and open a whole new storefront alongside BC Liquor Stores.
As was announced in December 2017, government is releasing details on the Province’s proposed retail framework. British Columbians of legal age will be able to purchase non-medical cannabis through privately run retail stores or government-operated retail stores and government online sales. B.C.’s Liquor Distribution Branch (LDB) will operate a new standalone network of public retail stores and the Liquor Control and Licensing Branch (LCLB) will be responsible for licensing private stores and monitoring the retail sector.
Nailed it!
