Not sure anyone has mentioned but CBC has developed a Great Canadian Baking Show. The first season is almost over, but i think all the episodes can be viewed at CBC online, (geographic restrictions limit viewing, unfortunately).
It's the same format as the British show, but slightly fewer contestants and episodes. Judges are Bruno Feldeisen and Rochelle Adonis. Doing Mel-and-Sue duty are Dan Levy and Julie Chan.
I've watched a few episodes and enjoyed it enough that I really hope they bring it back for more seasons.
Anyone interested can read about it or watch it here:
