About 1,000 people were forced out of their homes on Thursday after a hot water pipe burst and flooded a condominium complex with scalding water.

Three people were taken to hospital after the hot water pipe broke on the sixth floor of 4048 Living Arts Dr., near the Square One Shopping Centre, at around 5 a.m., including one woman who suffered first-degree burns on her legs and feet.

Another woman was taken to hospital with chest pains, while firefighters removed a third woman from the building after she went into labour.

Two cats died in the scalding water, which cascaded from the sixth floor down through the lowest parking level.

Mississauga Fire Platoon Chief Mike Head said the flooding knocked out power to the entire building and there was a risk of fire. Residents of the 30-storey have been asked to stay elsewhere until the scene has been cleared.

While those living above the sixth floor could be allowed to return home later Thursday, those living on the bottom six floors could be displaced overnight or longer.

Mississauga Mayor Hazel McCallion visited the scene on Thursday and promised to help those without home insurance and without any place to stay.

"We'll take care of how many there are. When disaster of any type, I can assure you we will respond," she told CTV Toronto.

Damage to the complex is estimated to be millions of dollars.
