A storm front swept across southern and central Quebec from west to east on Thursday evening and Friday morning, causing numerous power outages.

Early Friday, there were still about 40,000 addresses in the dark.

At the height of the situation on Thursday evening, nearly 50,000 homes had lost power.

The Outaouais region was the hardest hit, with nearly 24,000 addresses affected.

Nearly 8,000 Hydro-Quebec customers were without power in the Laurentians.

In the Capitale-Nationale region, Hydro-Quebec reported that approximately 6,000 addresses were without power.

Other regions were also affected, but to a lesser extent.

At the end of a hot and humid Thursday, a band of thunderstorms formed, prompting Environment Canada to issue a severe thunderstorm warning.

The storms mainly affected western Quebec, and the system changed to rain as it continued overnight.

The storms also affected Ontario, with nearly 80,000 Hydro One customers without power on Friday morning.

“Our crews are responding as quickly and safely as possible to restore service to customers affected by the storms moving through parts of southern and central Ontario,” the power distribution company said on its website.

Environment and Climate Change Canada’s thunderstorm warnings were all lifted on Friday morning.
