Heavy rain, high winds and even hail was reported across Toronto, the GTA and parts of southern Ontario tonight as a powerful summer storm hit the region.

Toronto was placed under a severe thunderstorm warning by Environment Canada late Sunday afternoon, a weather advisory that was later downgraded to a severe thunderstorm watch shortly before 7 p.m.

Three hours later, the national weather agency once again issued a severe thunderstorm warning for the city and several parts of the GTA ahead of the second wave of the storm late Sunday night.

About 1,000 Toronto Hydro customers were without power in the area of Bathurst Street and Eglinton Avenue and the area that is bounded by Burnhamthorpe Road, Kipling Avenue, Dundas Street and the East Mall but as of 10:45 p.m. the power was restored to all customers.

A transformer fire near Bloor Street and Lansdowne Avenue also caused a power outage for residents in the area, according to Toronto Hydro, however power was restored to the west-end neighbourhood at around 10:45 p.m.

Hydro One said that approximately 38,000 of its customers were without power across the province after the storm.

"It is expected that the number of customers affected by these storms will increase as the system continues to move across the province," Hydro One said in a news release issued Sunday night.

"Hydro One will provide updates on restoration times once the extent of the storm damage has been determined in each of the affected areas."

There have been no reports of injuries following the severe weather conditions.

Arnold Ashton, severe weather meteorologist for Environment Canada, told CP24 Sunday night that sporadic storm damage, including downed trees and power lines, has been reported from the Bruce Peninsula all the way to the Toronto area.

"It was pretty powerful," Ashton said of the storm. 

"This one sure packed a punch." 

At the height of the weather event, the wind speed clocked in at 94 kilometres per hour at Pearson International Airport, he added.

Reports of funnel clouds and tornadoes surfaced on social media however Ashton said Environment Canada can not confirm any of those reports.

“Usually when there is a fairly significant tornado that’s done appreciable damage with roofs off of houses or certainly injuries, we will hear of that but as of this stage we have not heard," he said. 

"We’ve heard all kinds of rumours about something and some rotation in the clouds and this sort of thing but really it is just been sort of an impressive squall that roared through with sporadic swaths of wind damage."

VELD Music Festival shut down:

The threat of severe weather prompted organizers of the VELD Music Festival to evacuate thousands of concert-goers from Downsview Park.

While spectators were understandably disappointed, many appeared to understand why the organizers chose to shut down the show.

"You can’t really blame the promoters. You can’t tell which days are going to be rainy or not," one festival-goer said as he was leaving Downsview Park Sunday. 

Many concert-goerers said they hope organizers will provide a refund due to the cancellation.
