the template for legalization was in fact alcohol. the largest players in the industry were well established before legalization and were in fact already corporate.
think of the bronfmann's - a bootlegging family mafia that became seagram's, and later corby's, the second largest alcohol marketing group in the world.
it's a similar trajectory aurora has emulated in cannabis. they were allowed to grow and build the corporate side long before legal, mostly as a medical producer, but they were never focused on that aspect long-term.
craft growing is essentially illegal in canada. the gov't sets a minmum size for grow licenses that automatically mean they have no choice except to play in the corporate arena. craft grow licensing has been skewered in canada as the gov't and main players can't agree on size.
the other thing hampering craft growing is the requirement to meet all the same standards and regulations as corporate growers. most can't afford the millions it takes to build a grow facility that meet those regulations.
