Horrible thought about the Anglican Communion

This idea being floated that we don't all have to be in communion with each other, as long as everyone's in communion with Canterbury.

Which I think I would cheer, but my personal bit is Canterbury, and if everyone's got to be in communion with us I can see an awful lot of "We can't do that because Church X would cease to be in communion with us" ahead. So no change in this particular bit of a small rainy island off the west coast of the European mainland. And yes I do have a horse in this race.

So how exactly does one move to Canada?
