It all depends on what are the numbers. In any case before deciding on vaccine mandates, certain conditions have to be satisfied:
1. Will the mandate increase vaccine uptake?
2. Will the mandate prevent overloading hospitals and clinics?
3. Are the health benefits for others proportionate to the risks for vaccinated?
4. Are less restrictive policies available that can achieve similar outcomes?
The UK decided to go with without vaccine mandates. They even revoked them for healthcare workers because with omicron variant they no longer made sense.
I am not saying what Canada should do, but at this moment vaccine mandates don't really seem worth to truckers, if not for all people.
