FWIW, my friend who lives in downtown Ottawa sent me this link, written by a neighbor he knows personally. (It’s an account of him meeting some of the truckers parked on his street, who are nice people and considerate.) My friend went down to meet them too, and confirms this account.

I live a few miles from downtown and so haven’t seen what’s going on personally.
The logic would be correct if, when Yovanni lied, he would always say it was Xavier Williams. In that case, there would be (roughly) 1⁄100 “Yovanni lies and says it was Xavier” for every 1⁄1,000,000 “Yovanni tells the truth and says it was Xavier.”
But if Yovanni lies randomly, and you have no prior that he would lie and say Xavier any more than he would lie and say anyone else, you have 1⁄100 * 1⁄1,000,000 “Yovanni lies and also Yovanni says it was Xavier” for every 99⁄100 * 1⁄1,000,000 “Yovanni tells the truth and says it was Xavier,” which is 99% truth.
