What? Canada as another Afghanistan? What are you talking about? Severing Europe from Asia? Putting aside that there are many other better ways to get between Europe and Asia than going through the Canadian arctic, who do you think asked us to be in Latvia? The Transatlantic Bond is one of the key NATO principles. NATO is worried about Russia being able to hamper communications from North America to Europe in the North Atlantic by way of the high arctic, but that is not based on the possession of given islands in the Canadian arctic archipelago. Stationing Canadian troops in the arctic is not going to prevent Backfires from trying to interdict forces moving across the Atlantic.
A joint Chinese-Russian seizure of an island in the Canadian high arctic is an interesting play. How do they get there and then what do they do once they are there? What size force would they place there?
All that being said, our first priority is Canada, then North America and then the world. Regarding the world, NATO has primacy. Our allocation of resources is guided by credible threats. That is why we have troops in Latvia as part of a deterrence mission. This does not mean that we ignore Canada - indeed we do not.
Regarding the article you posted, Canada can certainly be overstretched. We should be careful before making each commitment - which we are. This doesn't mean we bring everything home to look after the patrol base.
I won't engage in line-by-line, but I will try to address the Divisional question.
Regarding the Division level, what do you mean by "coordinate a Division within our own resources?" Do you mean the command and control of a fighting division on operations, or the coordination of day-to-day activities at home stations? Why do you ask?
I always want to take care when responding to you.
I don't think we will ever see the international situation, or for that matter the national defence situation, in the same terms.
I am strongly convinced that a primary reason for the lack of support for national defence in Canada is the ongoing tendency to argue that Canada lives in a fireproof house and has no need to be concerned.
At the same time Canadians get the message that we need to go looking for wars overseas. While it may be the right thing to do, it does tend to put our fireproof house at risk.

D-Day on the St-Lawrence, or even Resolute, has never been a possibility. Conventional warfighting is not a major likelihood in Canada.
Having said that nobody has declared war in any country in a very long time. Wars mix the state military with private industry, politics and criminals. Anybody can buy their way into a remote site in Canada and then start flying in security teams and assets. Add some disgruntled natives and a few bikers and pretty soon, IMO, the RCMP would be presented with a tactical problem outside of their skills and scope.

I think that we have a perfectly adequate base from which to build an appropriate Army Response Force. The Brigade.
Following on from 11th Abn and some of the US light brigades and divisions, and based on our recent Cold War history I propose 3 Infantry Brigades, 1 Armoured Brigade and 1 Combat Support Brigade.
The Infantry Brigades would be based on the three infantry regiments with 2 Rifle Battalions and 1 New Model Battalion (ISR/EW/UAS/CUAS/Cyber...) They would follow the basic design construct of the old Special Service Force.
The Cavalry Brigade would be based on the RCD, the LdSH and 12 RBC and Armoured Engineers- using the Swedish Pansar Combined Arms model.
The Combat Support Brigade based on 1 and 2 RCHA, 5 RALC and 4 GS Regiment.
.....
I would propose two active Div HQs, The distribution of Brigades within the Divs is not important. What is important is that each Division HQ is switched on an deployable and can absorb additional elements from Canadian and Allied forces. Adhocery as the rule.
Likewise for the Brigades - cross attachments to other Brigade HQs as the norm, and regular training with different modes of transport.

Why 2 divisions? Personal preference, a sense that the rest of the world organizes along divisional lines and a notion that Canada should be able to manage at least that level of commitment to sustain any degree of self-worth.
