I largely agree with Dr. Charron. I understand why governments turn to the military to do these things. They have a capability to do what no one else in the government system can, and it's a natural desire to look at what you have and see what you can use.
In terms of the military side as the defence side of this relative to assistance or aid to the civil power, I think you really are not talking about boots on the ground; it really should be undertaken by other agencies in Canada. There are also issues about whether government is organized properly to deal with the nature of the Arctic.
For the military question relative to the type of threats, when thinking in military terms, I think you're trying to look at cost-effective high-technology solutions to surveillance and reconnaissance rather than taking the boots-on-the-ground approach. That's RCMP, that's coast guard people, and those resources probably should be devoted towards their presence up there.
