Crews are hard at work in the Merritt Ave and McLeod Road area of Niagara Falls.
They're responding to a watermain break, so you can expect traffic disruptions.
If you're living in the area, your water may be slightly discoloured and it may taste off.
If this does happen, officials say you should run cold water out of the lowest possible tap in your home.
The City issued the notice at 1:28 p.m. this afternoon. It says the interruption could last between six to eight hours.
