Yes.
I saw that colleagues already talked about missiles. These remain a continuing threat. Canada has one foot in, one foot out with ballistic missile defence. It's problematic functionally, should a territorial missile arrive. There's research from 2018 talking about how NORAD might be used to address Canada's issues concerning strategic defence, and I would be happy to share that.
Territorial sovereignty in the Arctic was covered by colleagues previously, but I would add a couple of things. Russia has used the Arctic Council to securitize an institution that explicitly sought not to be brought into the political game. We see this very clearly. Russia is willing to destabilize multiple institutions to achieve gains in Ukraine. Canadian investments in Arctic sovereignty pale compared to American and U.S. investments.
Taken together, Canada has some level of partner support in managing or responding to these threats, but it's simply not doing enough.
