Even if you don't retain the person, find the biggest/baddest "men's rights" guy in the province, and get his business card. Then leave it in your nightstand drawer for your wife to find. If she asks you about it, say "I haven't made any final decisions about who's going to represent me yet, but I felt it was best to get some advice in order to protect myself, considering."
Maybe such a hammer hole card, not yet played (but able to be), will keep her playing nice on the visitation stuff, and just overall.
