Police maintained tight lines around the summit site.
"They're doing their best to try to keep their peace," said Constable Tim Garland, who characterized the police response as "measured and balanced."
As fresh officers were poised to work the night shift, police feared the worst may not yet be over.
"It's gonna be a very long night," said Mike McCormack, head of the Toronto Police Association.
Mr. McCormack said that the radical protesters who attacked police cruisers and police headquarters were absolutely "disgusting" - unlike anything he has seen in his two decades as a cop. He said he witnessed many attacks on police as he wandered the downtown core.
The dynamic in the crowd changed around 3 p.m. ET as police donned gas masks. Some parts of the riot line were as many as three officers deep as the crowd chanted: "Let us through!"
The crowd cheered when windows were smashed, including at an Urban Outfitters near Yonge Street and Dundas Street West.
"This isn't our Toronto. My response is anger," Mayor Miller told CP24. "People came here deliberately to commit this kind of act."
In a statement, Premier McGuinty condemned the vandalism and violence.
"Peaceful protest has always been part of the bedrock of our democracy. The vast majority of today's demonstrators have been peaceful and responsible. However, willful, mindless destruction and violence have no place in our province. I appeal to all involved to allow calm to prevail," he said.
Late in the afternoon, Craig Herbert borrowed a broom from his workplace, the Ram in the Rye, a Ryerson student pub, and went to Yonge Street near College Street to sweep up glass outside a Starbucks and a Tim Hortons.
"I don't want to justify a billion dollar budget by wrecking shit," he said. "I like my city."
Earlier in the day, thousands of demonstrators stood face-to-face with riot police at the corner of Spadina Avenue and Richmond Street West. Another line of mounted police stood behind them at the corner of Spadina Avenue and Richmond Street West. Protester set off flares, which filled the air with smoke and drew cheers from the crowd.
"We got them where we want them," one protester shouted. "Are the stores open in Chinatown selling fireworks?" the same protester yelled.
Near the MuchMusic building on Queen Street West and John Street, police pushed back on the most aggressive protesters with their batons and shields. One man looked to be defending himself with his bare arms. Some protesters threw objects across the police line, but none appeared to breach the police barrier. Some demonstrators stood behind and watched while the rest of the marchers slowly snaked west toward Spadina.
Several protesters were being treated for head wounds by fellow demonstrators amid reports that paramedics faced delays in getting to the area.
A Globe and Mail photographer was tackled by black-clad protesters after taking their picture. Some of his equipment was damaged.
