I haven't had any personal experience with the Fox Den, but most reports are positive, particularly because Tiffany is there now. (If you don't mind the higher rate for FS.)
The Fox Den is a lot nicer facility than BBC, which is pretty basic (only one shower, not in the rooms, and no Jacuzzi rooms.)
I started my MP experiences with several trips to Edmonton, visiting MMC and Cloud 9, and they are MUCH nicer than BBC and Great Pharaoh (my Vancouver visits).
Overall the E-Town MP scene is probably the best in Canada, for price and quality. (Of course, I'm a little biased because of the great memories of my 6 sessions with Nikita there).
