You'reright. The feds mandated cross border truckers be vaccinated as that industry in a matter of federal jurisdiction under the Constitution (British North America Act 1867, s. 91). However, the US also mandated it, as was their right as far as entry into their country goes. The provinces have instituted the other manddatesmasks, QR codes, etc. Might be just me, but when I want to protest something, I know my target.
