RE: Baby Registries...
I haven't registered in Canada, but have studied prices at Sears, BRU, TRU, etc., and I don't honestly think there's much of a price difference between them at all, especially for the big-ticket items.
When I did register (at Target in the States), I chose there because everyone I knew would be coming to my baby shower had a B&M Target location nearby, since not everyone was internet-savvy. If I had to do it over again, I would've registered at more than one place, and would've chosen a specialty baby store in addition to Target, because the specialty stores have a much wider selection of stuff.
HTH, and congrats :)
