Canadian Navy is actual in a huge shift right now. The main objective will be protecting are sovereignty in the arctic. Not only are the Halifax's going through a modernization program right now. BuT the RCN WILL be getting 2 possibly 3 Joint Support ships. We will be building are own, tho design is based roughly on the Norwegian Craft. Canada will also start producing the new arctic patrol craft. Thirdly the RCN is in the beginning stages on designing a ship to replace the gap left for decommission on our Destroyers. These are slated to start entering service in the early 20s. It would be a real shame to have a game based around the Arctic and not have one of the Navies that are best suited to fighting in it.
I'm not too sure that having some arctic patrol ships qualifies Canada as one of the best cold water forces.
