Dont get why he doesn't move them somewhere where he could drive to, like at the south of the border or in southern Quebec like Gatineau.
With an hour (or more) long commute nearly every day, he would not see the kids that much anyway. When you include long road trips when he wouldn't be home at all, it might not be worth it to uproot your family and move somewhere where you don't know anybody.
No matter what he does, it should be kept between his family. I find passing judgment on other people's family life from an outsiders perspective is pretty shallow. That said, I view this as a publicity move to bring attention to the cause he supports. He's bringing this type of scrutiny upon himself so it's fair game.
