I knew someone would mention that.
Nah, not going to cut it. You (as the new Canadian prime minister of awesomeness) will need something that can reach across the world and back with no problems getting there in a hurry. Even if an AIP diesel can stay submerged, they aren't going to have the type of range and transit times you'll need.
You need a global sub, one that can get from the east coast of Canada around the tip of Africa and up the african east coast and all the way back without thinking twice about it. Or that can go from the west coast of Canada across the pacific to the phillipines (a 14000 mile round trip iirc) without it taking a month to get there and without worrying about fuel.
