Why waste money? Defence bucks are spread thin enough as is. We have once port for the Pacific (Esquimalt), Atlantic (Halifax), and now an Arctic port in Nanisivik.
I'm tired of the tossing of money to placate regionalism, especially defence money.
Well once more shipping starts to happen in the Arctic Churchill is most likely going to be a major link and commerce centre. Either that or possibly Rankin Inlet. The point of Churchill though is it would have been cheaper to place these things there and since it is more accessible and has more of an established community it would probably be a better choice.
Also the defence budget should be increased then. Id put it at 45 billion dollars a year however many might not agree with that.
