Tensions flared at a homeless encampment in Toronto on Wednesday as city officials, flanked by dozens of police officers, moved in to clear the site. Residents and their supporters shouted at police, who in turn threatened many with arrest. At least three activists were handcuffed and taken away from the encampment at Lamport Stadium before city officials moved out. Several hours later, police and the city gave up after clearing out one tent and two small wooden shelters. About two dozen remain.
