Gatineau crews have been working through the night to repair a broken water main.
The broken pipe on Alexandre-Taché Boulevard caused a drop in water pressure Monday evening.
Residents started reporting no water in Hull around 6:30 p.m.
Gatineau Fire reported four homes were evacuated on Belleau Street due to the accumulation of water in the basements. The break also impaired water and natural gas supplies to the homes.
Police closed Alexandre-Taché in both directions between Boucherville and rue Hormidas-Dupuis to allow crews to repair the pipe.
Environment and Climate Change Canada says the Fontaine Building in Gatineau will be closed today due to low water pressure. Limited access will be granted to employees to get their laptops to work from home.
The City of Gatineau has since issued a preventative boil water advisory for the area.
⚠️ Avis préventif de faire bouillir l'eau pour une partie du secteur de Hull. Cet avis, touchant environ 24 500 résidences, est en vigueur à compter de maintenant, et ce, jusqu'à sa levée.
