The Royal Canadian Navy (RCN) and Royal Canadian Air Force (RCAF) used to be very good at theatre and local anti-submarine warfare (ASW). How they rate now is not going to be something available to the general public, as ASW is one of the very classified areas of defence. The Canadian public will see how good the RCN and RCAF are these days if and when there are public reports of submarines off our shores including the Arctic. ASW was and remains a high end capability that Canada can contribute to our alliances, especially now that there seem to be more frequent not-friendly submarine deployments in the sea approaches to Canada. It will be interesting to see what mention ASW gets in the outputs from the current defence policy review.
