I seriously doubt that fentanyl come out of Canada into the USA was made in Canada. Probably just passing through on the way from China. Why would it go to Canada first? Because Canada has thousands of kilometers of border with the USA. And a lot of traffic at the legitimate crossings. Canadians pass into and out of the USA with relative ease.
