In Vancouver, in the days when I worked at downtown, I fequently saw some people who would wear different styles of cloth to attend different types of protests, such as "human rights for first nations", "environment protection against pipeline constructions", "Animal welfare" etc. I could not help laughing silently. Those people are paid by different organizations to do the work. Same is the truck fleet protest.

My opinion is that you are free to decide whether you want to be vaccinated or wear masks, but you should not take any public health care resources if you indeed catch Covid. In that way, it is fair to the majority of people who wear masks and take vaccines to protect both self and others.
