Severe thunderstorms sweep across central Canada and cause widespread power outages, according to multiple reports. Global News and the Winnipeg Free Press say more than 30,000 Hydro-Québec customers in Quebec remain without electricity after damaging winds and thunderstorms. City News Toronto reports a broader regional impact, saying roughly 55,000 hydro clients are without power across Ontario and Quebec combined, with figures rising higher at the peak of the outages. City News Toronto also notes that, at the height of the storm, Environment Canada estimates more than 214,000 customers in Ontario and nearly 140,000 customers in Quebec were knocked off the grid. Reports describe the outages as being driven by damaging winds from the thunderstorms. Authorities and utility providers work to restore service, though the timing and extent of restoration are not specified in the provided summaries. Overall, the sources agree the storms disrupt electricity supply across southern Quebec and parts of Ontario, with outage numbers decreasing from peak levels but still affecting tens of thousands of customers.
