The City of Gatineau has issued a boil water advisory for a large section of the city east of the Gatineau River after a watermain break.

The advisory will take effect at 9 p.m. ET Thursday and be in place until further notice.

The entire Gatineau sector is under the effect of the advisory.

During the advisory, residents must boil their water for one minute before consuming it.

Tap water may also be discoloured. In that case, residents are advised to open the cold water tap and let the water run until it becomes clear again.

Tap water can safely be used as is for baths, showers, laundry and doing dishes.

Once the advisory is lifted, residents or businesses will have to open all cold water taps or water fountains and let the water run for one minute or until it is cold before using it and throw out any ice that was made while the boil water advisory was in effect.
