There is nothing on https://old.reddit.com/r/Coronavirus/ or https://old.reddit.com/r/CoronavirusCanada/ which is where I would usually to go get a link to the actual ruling / policy. I will keep checking over the next few days to see if the news gets picked up.
Both r/CoronavirusCanada/ and r/Coronavirus/ are heavily moderated (censoring anything that may promote vaccine hesitancy). People are tiring of the censorship and going to other platforms. One that is less moderated is https://saidit.net/s/Coronavirus/ but not that many users. I know they are gathering someplace just haven't found it yet.
