Hydro Quebec was forced to turn off electricity for about 7,000 customers in Monkland village and Hampstead while the gas leak is repaired.

Construction is taking place on Harvard Avenue near Monkland.

Hydro Quebec is estimating that power will be restored during the lunch hour, but some residents in the affected area had electricity by 11:15 a.m.
