The issue of selection at retailers we could debate infinitely, I think. Increased selection wasn't exactly my experience in the US and Quebec, just larger cans. The current selection at the LCBO/Beer Store suits my needs pretty well. I wish every location was more consistent, but overall I think they do pretty well. You're correct that retailers would no doubt capitalize on the niche market, but I still can't decide about how the prices would fluctuate. The brewers may up their prices and buying power is of course important. Given my poor experiences across many different markets in Toronto, I would hazard a guess that the consumer would get the short end of the stick, at least in terms of price. Letting a free market dictate price isn't always the best course of action.
