"I would say that we're trying our very best to do this in a way that I've described many times as compassionate but also firm," Tory said. "We must find safer, more healthy, legal, indoor accommodations for people who have many needs for support in their lives, provide those supports, and do it in a way that preserves everyone's safety."
Tory also alleged protesters have gotten in the way of the City staff doing their job and said some had even followed staff home.
"They have been harassed at their home, they face all kind[s] of verbal abuse, the likes of which most people would never be expected to put up with at their jobs from, frankly, the protesters," Tory said.
The mayor also added that a large number of protesters on the scene "necessitate" more and more police officers.
