That's absolutely correct. The Canadian Armed Forces, the Department of National Defence and other entities of the Canadian government are actively engaged in supporting sovereignty and defence of the Arctic.
In NATO itself, the area of operations of NATO as SACEUR is continental Europe and into the Atlantic. The Canadian Arctic is not part of the NATO area of operation. It is part of the NORAD area of operation. With that said, everything we do in our Arctic helps to contribute to strengthening, supporting and defending the northern and western flanks of the alliance.
