As a result, a woman was taken to hospital for frostbite when she became trapped in her vehicle due to the break.
The intense water flow managed to freeze vehicles in place and flooded seven row houses.
According to firefighters who were on the scene, the water was hip-deep in some spots on the streets.
Homeowners affected by the break say the water was nearly a metre high in their basements and was enough to damage appliances.
At least half a dozen people were removed from their homes on an inflatable boat and were taken to a cultural centre that acted as a make-shift emergency shelter.
A spokesperson for Epcor Utilities says the cause of the watermain break is not clear. Although it was confirmed the break occurred in a main water transmission line.
