City crews managed to restore running water on Sunday for about 30 people living near the corner of St-Antoine Street West and Atwater Avenue.
"When the water came we were all running back to our apartment," said resident Maria Kounavios.
They had spent nearly two weeks using bottled water and melted snow to cook, drink and perform household functions, like manually flushing the toilet.
However, residents' excitement was a bit short-lived. Once the pipes thawed, city workers found a crack in the main pipe that serves all three buildings, Kounavios said.
She told CBC Daybreak host Mike Finnerty on Monday that she was told the water would stay on until it was absolutely necessary to cut it off to repair the cracked pipe.
In the meantime, she said, residents are rejoicing by taking showers in their own homes.
