A boil-water advisory issued for a portion of Laval has been lifted. 

The city issued the preventative advisory Tuesday, telling 150,000 residents in the western third of the city to bring their tap water to a rolling boil for a minute before consuming. 

The city said it was due to a drop in pressure out of its control at the Chomedey filtration plant.

Test results later showed there was nothing wrong with the drinking water. 

Officials are still urging residents to conserve water whenever possible because of the warm weather.
