If you haven't seen it yet, do check out the Canadian Law Blogs List by Steve Matthews (Vancouver Law Librarian Blog). As far as I know, this is a definitive list. If you know of any other blogs that should be included, pass along the info to Steve (or, in a pinch, to me).
It's one of those things I wish I had thought of doing. Steve has received some well-deserved accolades for the compilation.
