After weeks of dry, warm weather, Ontario was hit with a dramatic turn on Sunday night, as heavy storms and lightning lit up the skies across the province.
From Toronto to all across the GTA and beyond, residents managed to capture jaw-dropping photos and videos of the storm, including ominous cloud formations and sheets of rain, some of which looked almost too surreal.
The storm was certainly no surprise, as Environment Canada had previously warned of severe thunderstorms moving through southern Ontario on Sunday night into Monday morning, with the potential for up to 50 millimetres of rain, wind gusts reaching 90 km/h, and hail as large as 2 centimetres.

In Waterloo Region, the storm damaged trees and power lines, and residents there and in nearby communities witnessed a striking sight — a massive shelf cloud rolling across the sky. The clouds, which often mark the leading edge of a thunderstorm, can appear to rotate along a horizontal axis.

Photos of the storms quickly spread online, with many people noting that the scenes were so surreal that they looked AI-generated. One shot, shared on X, shows lighting sparking up the sky, while another shows a massive cloud formation looming over a residential neighbourhood.

The storm comes just after a notably dry period of weather in September. Before last night's storm, Toronto-Pearson had only recorded 19.3 millimetres of rain throughout the month, which is far below the seasonal average of 69.4 millimetres.

Even with risks of localized flooding, the storm provided an astonishing display for us spectators. One video, shared by meteorologist Anthony Farnell, shows just how fierce the system was as it swept through the sky.

If you're a fan of the classic, dreary fall weather, you'll be happy to hear that Toronto is in for some more precipitation and thunderstorms this week. According to The Weather Network, there is a risk of thunderstorms on Monday in Toronto in the late afternoon to evening, as well as late night from 11 p.m. to 12 a.m.
There is also a risk of thunderstorms on Tuesday and Wednesday, as well as soaking rain on Thursday. By Friday, conditions are expected to clear up, with partly sunny skies taking us right into the weekend.
