Environment Canada has issued a severe thunderstorm watch for Toronto and much of the Greater Toronto and Hamilton Area (GTHA) as of Thursday afternoon. The agency warns of potential 90 km/h wind gusts and localized rainfall exceeding 60 millimetres, following a series of earlier thunderstorm warnings that have since been lifted.
Storm Impacts and Regional Disruptions
The weather system has caused immediate infrastructure disruptions across the region. In downtown Toronto, police reported flooding at the intersection of Simcoe Street and Front Street West, leading to the closure of Simcoe Street between Front Street West and Bremner Boulevard. No injuries have been reported in connection with the flooding.
In Halton Region, high winds have resulted in multiple reports of downed trees on roadways. Provincial police have also closed Highway 5 between Highway 8 and Middletown Road near Dundas due to a combination of a downed tree and hydro wires. Authorities are advising motorists to seek alternate routes and remain off the roads if possible.
Did You Know? Hydro One advises that during a storm, residents should report power outages using a cell phone rather than a landline to avoid the risk of receiving an electromagnetic shock.
Power Outage Status and Utility Response
Electrical service remains inconsistent across parts of the GTHA. Milton Hydro reported that approximately 8,000 customers were initially without power, though service was restored to about half of those homes by 4:25 p.m. Crews continue to work on tree removal and line repairs, with an estimated restoration time of 8:00 p.m. for the remaining 3,668 affected homes.
Burlington Hydro has also confirmed multiple outages throughout its service area. Utility crews are currently assessing damage to ensure power is restored quickly and safely. As the storm tracks toward the Niagara region—impacting areas including St. Catharines, Welland, Fort Erie, and Cayuga—utilities remain on high alert.
Preparedness for Extended Outages
Hydro One has encouraged customers to maintain a 72-hour preparedness kit to manage potential electricity loss. Recommended supplies include a battery-powered flashlight and radio, portable chargers for smart devices, a first aid kit, and at least two litres of water per person per day.
Residents are further advised to unplug electronics and appliances to prevent damage and to keep refrigerator and freezer doors closed to preserve internal temperatures. As the storm continues to move through the late afternoon and early evening, individuals are urged to monitor weather alerts and seek immediate shelter if conditions deteriorate.
