An afternoon fire that sent two people to the hospital is under investigation. 

After 1 p.m. Monday, fire crews were called to the 300 block of Mountain Avenue, finding smoke pouring out of a three-story apartment building. The fire was contained to one suite, but that suite is now significantly damaged. Two floors have smoke and water damage.

Two people were sent to the hospital after the fire, and many of the building's occupants self-evacuated before crews arrived. One person is in unstable condition and another patient is stable.

The City of Winnipeg says in a release that Mountain Avenue between Charles Street and Salter Street is closed.

"Water used to fight the fire has created some patches of slippery conditions in the area," the city says.

It will remain closed until fire operations wrap up. and the street is de-iced.
