Mt Baker Council of the BSA used to own a camp called Black Mountain that is less than 1 mile from the Canadian border. Many times per week people would walk through camp with daypacks on their backs full of drugs.
More than a few of those daypacks were discovered by campers and returned to the camp office. We’d call Customs.
So, the notion of a border wall with Canada isn’t something I’d necessarily dismiss out of hand. There are SO MANY Chinese living in BC. I have ZERO doubt the CCP is running ops out of BC (Vancouver) and Seattle.
Would not surprise me at all if there is talk of such a fence next term. Not saying there will be, but would not be a stretch.
The US/Canadian border is twice as long as our border with Mexico - not even counting the roughly 1,500 mile border with Alaska.
Although a continuous barrier is cost prohibitive, a lot of the technology (surveillance, detection, tracking) developed to address the flood on the Southern Border, is deploying to the Northern Border as well.
