If anyone is curious about this, I recommend going over to Carseat.org and visiting their "Canadian and other international issues" board (perhaps that wasn't entirely correct but you won't mistake it for another board). I haven't been in awhile so scroll down and see if this subject has been tackled recently.
BTW, you don't have to register to post over there but please glance at the other subjects, just to be sure no one gets annoyed if they have discussed this.
