On what was meant to be a day of celebration, a massive storm event put an early end to Canada Day plans throughout Waterloo Region.
Between 5 p.m. and 6 p.m. on Wednesday, temperatures in the region dropped from 34 C to 23 C, and with it came winds rising to over 60 kilometres per hour.
The Waterloo Regional Police Service said that its communications centre received 64 reports of dangerous conditions brought on by the storm between 5 p.m. and 8:30 p.m. These included downed trees on roadways, damage to houses and trailers, and downed power lines. Kitchener’s Victoria Park — the site of many Canada Day celebrations — saw damage to both trees and power lines in the area.
In a social media post, the Township of North Dumfries described a chaotic scene as the winds picked up in Cowan Park for the Canada Day celebration.
“In a matter of minutes, vendor tents were badly damaged, debris was scattered across the fields, portable washrooms were tipped over, and then we lost power,” it reads. “At the same time, our Fire Department was called to respond to a structure fire due to a lightning strike, while Public Works crews were dispatched across the Township to clear fallen trees from roads and respond to storm-related issues.”
Tree clean-up, damage and the demand on municipal staff are continuing on Thursday.
“As a small municipality, our staff wear many hats. Many who were working the event were now also dealing with the storm’s aftermath,” the township noted.
A variety of other downed power lines resulted in power outages for residents throughout the region in the late evening. GrandBridge Energy posted to X shortly after 6:30 p.m. that just under 964 customers had lost power in the areas north of Concession Street and west of Franklin Boulevard in Cambridge.
Even more were affected in North Dumfries and Ayr, with approximately 2,865 residents losing power shortly after 6 p.m.
Most residents who lost power in the storm had service returned shortly before 9 p.m.
With most of the Canada Day fireworks celebrations, some municipal events were forced to cancel or postpone their activities due to the dangerous weather. In particular, the City of Cambridge announced via Instagram shortly before 7 p.m. that it would be cancelling its Canada Day fireworks display due to the incoming storm front.
The organizers would promise hopeful attendees that the display would be postponed to a later date.
The volatile heatwave that struck the region as early as Sunday is still projected to continue until sometime on the weekend of July 4-5. Thursday will see a projected high of 34 C, which will feel closer to 45 with the humidex.
The stormy conditions from Wednesday may also continue, as Environment Canada projects a 40 per cent chance or higher of thunderstorms or showers every day until July 6.
