Toronto police officers used tear gas to force a woman out of her home on Eastern Avenue near Carlaw Avenue, late Wednesday afternoon.
The woman was wanted on criminal harassment and other charges.
Police said they had been looking for her for months.
Investigators called in emergency task force officers because they believed there were weapons were inside the home.
The woman refused to open her door, so the decision was made to fire tear gas into the house.
"I believe that they tried verbal communications," said Const. Rob McDonald. "That didn't work and they used [tear] gas to help extricate her."
Paramedics took the woman to hospital as a precaution.
