A five-alarm fire at a 15-storey high rise near Jane Street and Finch Avenue West where flames were seen shooting from apartment windows is now under control, Toronto's fire chief said.

Fire Chief Matthew Pegg told reporters Friday evening from the scene at Gosford Boulevard and Shoreham Drive that 911 calls started coming in just before 5:30 p.m.

At the height of the fire, flames had spread to multiple floors said Pegg, before crews "gained the upper hand." Twenty-two fire trucks were on the scene along with some 100 fire personnel.

Toronto police said in an earlier tweet that there were reports that children were trapped on a balcony because their apartment was engulfed in flames — but Pegg later said that "there is no indication that anyone is trapped or missing." One person was seriously injured, but their condition has since been upgraded to stable.

Five other people were treated for injuries on the scene but did not require transport to hospital, said Pegg.

Elevators in the building have failed, Pegg said. A number of people who live in the building are now "protected in place," Pegg said, which means they can stay in their apartments if they don't see smoke or fire.

The Driftwood Community Centre is also open to help provide shelter to anyone displaced. There's no word yet on how many people have been forced out of their homes.

So far, there is no word on what caused the fire, or just how long it might take to put out.
