Drug flows...surely you must be joking. As noted in https://duckduckgo.com/?q=How+many+drugs+flow+into+the+USA+from+Canada+each+year%3F&ia=web, less than 2kg of fentanyl enters the US from Canada each year. Similarly, the number of humans trafficked across the border into the USA from Canada is tiny....so, sorry, you are mistaken. Dude, our issues with the US started centuries ago, and in 1890, the Yanks tried the same technique they are failing with now, which is to attempt to annex Canada by destroying their economy. Once again, American arrogance loses.
