If it happens, it may not be as fearsome a scenario. It certainly wouldn't cover the Beer Stores, won't cover the private wine stores and vineyard sales, and probably won't cover the small town corner stores that have lcbo sections. And there has been an announcement that management will try to keep some stores open.
Our regular brands of various wines and spirits would still be available, but from the distributors, possible with quantity minimums. They're not the most well-publicized folks, and certainly tracking a brand or label to a distributor takes more than google skills.
The thought here is that if the trike goes ahead, this or another thread could be used to help track labels back to distributors, or introduce groups that might want to band together to meet some of the minimums. Cheers!
