Well, to be fair, you do come off as if you think it's as dangerous as the common cold...... Even though it was the number three cause of death during the height of the pandemic.
I'm not Canadian. I do know that the death count here in America has dropped dramatically since the vaccine. So, the vaccine may not stop infection, but it's keeping the death toll down. The vaccines available in Canada correct?
What you don't know is if a mask would of stopped enough virions to avoid infection. That's why, during the pandemic, it may have been prudent to mask up.
And you're a dimwit who needs to stay out of adult conversations. I guess you forgot that before the vaccine, covid was the #3 cause of death Worldwide. You're just one more of the many profoundly stupid folks on this forum.
Answer the question... How many virions does it take to get infected? Nobody knows. So how do you know that a mask won't help stop infection?... You don't.
