I Like Creemore Lager for sure, Mill Street's Tankhouse Ale, and Steam Whistle if it's super-cold as a pilsner, in the summer. Keith's like Creemore, isn't so much of a micro anymore, but I enjoy their ale on tap after I play squash, and want something not too heavy.
Anytime I'm in Quebec, I love just about anything from Unibroue, but can't really imagine drinking the more Belgian-types all the time.
In terms of beer can chicken, it's the only way to fly! I always put some of the rub in the beer can, along with a crushed cove of garlic. It's pretty hard to mess up, cause the beer keeps the chicken from drying out.
