This is the first I've heard of this, and it seems like an odd fit to me. Moosehead is already in Ontario via Niagara Falls Brewing, so unless it's a question of volume, I don't see what they need the others for. I could maybe see Brick and Big Rock getting tighter, since I think they're already doing brewing for each other, but Lakeport?The potential sale of Sleeman is fueling speculation in the industry about other possible sales and mergers.
A potential merger between New Brunswick's Moosehead Breweries, Ontario's Lakeport and Brick Brewing Company and Calgary-based Big Rock Brewery could create a new national company that would be larger than Sleeman, said beer industry analyst Peter Holden of Toronto-based Veritas Investment Research.
I dunno, this just looks like something that someone pulled out of their ass and managed to turn into an "industry rumour"...
