There's a couple of videos there, but one of them

is definitely an Air Canada plane, it looks like 9 across so I assume a 787, and it shows someone being taken off the plane on a stretcher by people wearing masks.
That said, I'm skeptical about the rest of the story for two reasons:
1) The video is dated Jan 29, now 2 days ago - and I assume that if multiple people were being held in quarantine in Toronto it would be on the news by now
2) They are taking the person off (on the stretcher) while all the other passengers are still on the plane. That looks more like the behavior that I'd expect if someone had a suspected heart attack - the plane pulls up to the gate, they ask everyone to stay seated, and the ill passenger is the first off the plane. If they really thought this was the coronavirus, then I'm skeptical that the best approach would be to wheel the infectious patient past as many other people as possible ... I would have thought they'd de-board the plane first.
So who knows (certainly not me), but my hunch is that this was an ill passenger being de-boarded (deported?
). It's not surprising to me that the first attenders are wearing masks and gowns, but that doesn't mean this was a coronavirus case. Seeing them dressed up like that may have scared the other pax, and maybe that's why this video got posted with the title that it did ....
