As I said, the inability of the US to control its Southern border poses a threat to Canadian security. Any wall on the Northern border is to prevent the bad guys from getting into Canada from the US. We need to get control of our Southern border, which will make the Northern border more secure for Canada.
The reality of the situation is there is less security on the Northern border than there is on the Southern border.
And do you know why that is the case? It has to do with risk assessment. We don't need as much security on the Northern border as we do on the Southern border.
You didn't answer my question: Do we need a wall between Alaska and Canada?
Well if you are only worried about illegals but Terrorists well see The U.S. Customs and Border Protection agency office says you are wrong and I am right:
Canadian Border Bigger Terror Threat Than Mexican Border, Says Border Patrol Chief
And as far as Alaska goes once we secure the lower 48 we can work on a plan for Alaska.
Illegal aliens are part of the problem not the only problem securing our borders means keeping out the nutters with chemical and biological weapons and shoulder fired missiles to take down planes etc. Right now they can sneak onto Canada's borders and drive across the Northern Border and we would never know.
We can build multiple Border Guard/military bases on both borders and give some much needed jobs to younger adults and they would be doing something useful. It is a win/win situation. Doing nothing on the Northern Border is defeatism/liberal dogma.
