The extended cold snap and shortage of permanent shlet beds in the city prompted staff to find other spaces for the city's homeless.
The Moss Park Armoury was set to open on Monday, but Mayor John Tory announced Saturday it would open the doors that night, 36 hours ahead of schedule.
City staff said in a news released "Activation went smoothly with the opening of the Moss Park Armoury as of 7 p.m. last night."
"With this, and the increases in warming centre and respite capacity, as well as additional outreach teams on the road overnight, there were services available for everyone wanting a warm and safe place to go."
According to the city the warming centre at the Regent Park Community Centre saw 67 people overnight and the warming centre at Metro Hall hosted 35. Both facilities will continue to operate on a 24/7 basis until further notice.
One-hundred-and-sixty of the 200 shelter beds at the Better Living Centre were occupied overnight.
Officials said street outreach teams encountered 44 people outside but only three accepted service.
The city can use the Moss Park Armoury site as a winter respite shelter for two weeks.
