Three people have been injured in a two-alarm blaze in Scarborough.
Firefighters were called to a building on Lawrence Ave E, near Orton Park Rd at about 7:30 p.m.
Paramedics say two of the patients had no vital signs when they arrived. A man and a woman in their 60's were taken to hospital where they remain in critical condition.
Police say the fire, which has been put out, was contained to one unit on the 10th floor and the Ontario Fire Marshal's office is investigating.
Fire officials say the smoke was so thick on the floor that they had a hard time seeing the apartment numbers when they arrived.
Some of the neighbours were evacuated as a precaution.
