More than 20,000 local customers are without power after Thursday evening's series of thunderstorms.

Severe thunderstorm warnings rumbled across eastern Ontario and western Quebec from about 6:30 to 10:30 p.m.

When the storm was at its worst, it produced a tornado warning around Sharbot Lake, gusts of wind up to 90 km/h and lightning, Environment Canada told Radio-Canada.

CBC News is checking and it's not yet clear whether a tornado happened.

As of 3 p.m. Friday around 14,000 customers were without power in eastern Ontario, according to Hydro One, and about 9,000 addresses in the Outaouais were out.

The Bancroft and La Pêche areas have the most customers in the dark. It should take most of the day for power to be restored in Bancroft, according to Hydro One. Nearly half of its customers don't have power.

Hydro Ottawa does not list a significant number of outages. There were more than 45,000 local customers without power mid Friday morning.

Photos from of Chelsea and Wakefield north of Ottawa show trees that were partially uprooted or snapped and Hydro-Québec workers responding to fallen branches which hit power lines.

In Gatineau, the Festival Parasol had to be cancelled Thursday night thanks to the weather. Otherwise, Gatineau police said they only responded to minor incidents like fallen branches.
