Yep. it quickly became an anti-vax, anti-mask protest disguised as a trucker's protest. It seems money for the protest is coming from the USA, plus professional protesters.

Workplaces have a right to set the rules. Public places need regulations until the pandemic is over. There is still lots of work for unvaccinated truckers in Canada.
