Jack... if you are going to Toronto - try McVie's (sp?) Irish Pub on the corner of Jarvis and King. Great live music on weekends.

As for my favourite. It no longer exists but it was the Buffalo Paddock in Banff. Nothing special except that it was there that I first heard good live folk music and it was sort of a turning point for me muscially. After that evening, the music of people like John Prine and Emmy Lou took over my record collection from Nazareth and Deep Purple.
