That may not be true. It is common for governments to implement the really unpleasant policies by using businesses as an enforcement arm (eg, surveillance via banks and telecom companies). It bears asking why companies have all, in coordination, picked up a set of policies that are both ineffective and divisive - it is entirely on the table that it is because of government pressure in the form of OH&S guidelines.
Firing unvaccinated people barely does anything w.r.t. changing the odds that people get COVID eventually. We've seen ample evidence that being vaccinated doesn't change the transmissible situation. So why are companies doing this? Their employees are still going to turn up and transmit COVID. By this point, the anti-vaccine types have probably caught COVID and gained natural immunity anyway so these policies would represent companies shooting themselves in the foot. It is possible they'd do that of their own initiative but it is nevertheless a bit weird.

Why do you think these protests have just mushroomed up? Have trucker protests been an ongoing thing in Canada for many decades?
