If you are vaccinated, you are done with the pandemic. Morally, ethically, and practically. You should be allowed to return to actual, pre-pandemic normal. End of story.
If enough people still get sick at once there could still be a collapse in a local health system due to overloading.
Given the uncertainty with new variations of COVID isn't it better to err on the side of caution and try to protect both the health systems and as many people at once?
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.
What if you have children who are not yet eligible for the vaccine?
"Covid-19 has killed 280 children under 18 from January through September 2021, the time span in which the alpha and delta variants were active. Flu and pneumonia, heart disease, drowning, guns, and motor vehicles were all deadlier to children during the same time periods annually from 2015 to 2019 (the latest years with available data)[0]."

From what we are seeing the vaccine side effects are similar but considerably milder and short term, the virus sometimes has long term negative effects (lung capacity, fatigue, weakness, inability to concentrate…)
