Interesting that there are no current transpacific cables at all landing in western Canada. Makes the area very dependent on the neighbour to the south (which is an earthquake risk, as well as a political risk).

Those will connect with arctic and atlantic undersea cables, so Canada wouldn't be completely cut off.
Oh, come on. Maybe an earthquake risk. But, really, "political risk"? The longest undefended border in the world?
