About 10 police officers, some in blue plastic gloves, appeared to be going through potential evidence on the patio of the University of Toronto's Graduate Students Union pub.
Two kilometres to the southeast, near Yonge Street and Edward Street, a group of about 20 officers had about 11 people standing against the wall with their hands up outside The World's Biggest Bookstore. The officers had the people's belongings, mostly backpacks, splayed across the sidewalk as they went through them. The belongings included water bottles, clothing items, and blankets.
Sergeant John Holmes confirmed later that morning that 11 individuals had been arrested at the scene and would be taken to the Eastern Avenue detention centre. He would not say what specific crimes the individuals were suspected of, but said that they were G20-related.
The people, mostly wearing jeans and t-shirts, appeared to range in age from their late teens to early twenties.
A few minutes later, about a dozen vans carrying more officers drove up, including a court services van. "They're all going in. All of them," one officer was overheard saying.
Officers began preparing large plastic bags and loading the people's belongings into the bags. Police cordoned off both ends of Edward St., between Yonge Street and Bay Street to prevent vehicle or pedestrian access to the area.
Lucas Polak, 26, said he was across the street when the takedown occurred.
"There were a group of kids walking eastbound and three vans were following them," he said. "They weren't doing anything and they just came and took them down."
He said he saw the officers jump out the vans and grab the people by their shoulders and move them against the wall. "It's kind of scary," Mr. Polak said.
Officers at the scene declined to comment on why the people were being detained, but one said, "We don't know what kind of substances are on them."
Included in some of the peoples' belongings were water bottles, a two-litre juice container, and various beverage cartons.
The Integrated Security Unit said police had made the arrests at U of T after receiving some information that the people there had been involved in some criminal activity.
The security unit earlier said police would be rounding up protesters for offences committed at earlier protests.
"A number of arrests had taken place, so police were saying they would look at the best time to arrest people," said Jillian van Acker, spokesperson for the security unit.
Nathalie Des Rosiers of the Canadian Civil Liberties Association said several group members who had been monitoring police activity at the protests over the previous days had been arrested and the association had been unable to contact them.
"I've been e-mailing the police to try and get some action and we've been getting the hang-up," she said.
Ms. Des Rosiers said the group's monitors had recorded several alleged violations of civil liberties by police, including officers surrounding and searching people on the street and making arbitrary arrests.
"We're very concerned that they're casting their net very wide and a lot of innocent people are being caught in it," she said, citing arrests made at Queen's Park and a peaceful protest outside the Novatel Hotel Saturday night.
After Saturday's sometimes-violent protests, several downtown Starbucks were closed Sunday morning, some with their windows covered in boards.
Sawdust filled the cracks in the sidewalk outside a CIBC branch at College Street and Bay Street, where the smashed windows were covered with hastily laid plywood. Even the street-access ABM was boarded up.
The Toronto Transit Commission restored full subway service, with all buses and streetcars running on their regular Sunday schedules, after having shut down downtown subway and streetcar routes on Saturday evening. GO Transit resumed all train and bus service to and from Union Station.
Early Sunday, Stephen Harper's director of communications, Dimitri Soudas, called the violent protesters "a bunch of thugs who pretend to have a difference of opinions and instead choose violence in order to express those so-called differences of opinions."
