A couple of links:
I haven't been to the Beer Store in years. They take a lot of abuse on other blogs but I think the LCBO does a pretty reasonable job of acquiring unusual and interesting beers. The site has a great product search function which permits a certain degree of browsing by country, for example. A proviso: the function that lets you know how much of a product is at a particular store is not 100% accurate.
I keep up with the Ontario Craft Brewers Association by way of the second site. Not every craft brewer is a member of the association but this is still a helpful site. I especially like the advance notice of the Discovery Pack and what will be contained.
