Dress up as a polar bear and go in through the north pole.

I was actually thinking about "light weight" (relatively anyway) survival recently. A crossing into Canada is a fun scenario to frame that. I imagine the limitations would basically be 1 large ("camping") backpack, whatever you can fit in it, and anything you can strap to your body/carry while maintaining a reasonable walking pace.
Crossing into Canada can be done at many points, since the border is so massive. The main issue would probably be getting far enough away from the border that a filthy man with a rucksack wouldn't arouse suspicions of illegal border crossing. I estimate this will turn it into at least a 6 day journey by foot. Remember, you will be walking and burning calories.
How would you do it?
Between cameras and drones this probably accurate. I imagine they have some sort of system which if a large enough animal passes by, similar to how home alarm systems work, would prioritize that camera for the human monitor. And it's not like they only watch the border itself, they'll try to detect you approaching and leaving.
