"Our crews got it knocked down but three homes in the middle of these five have suffered significant fire damage and there's a good chance that the residents from all five will be displaced.," said Pierlot.
Victims services workers were at the scene trying to help people deal with the aftermath.
Alicja Holm said there were flames shooting into the air.
"I came into the complex and saw gushes of black smoke coming into the sky," she said.
Jeff Borden, who live across from the homes on fire, said there was a lot of heavy smoke and he couldn't drive into his street.
"The flames burst out of the window of one of the homes ... and a section of another home's roof was caving in," he told CBC News.
An investigation into the cause of the fire is underway.
