From heatwaves to hailstorms: Environment Canada's top 10 weather stories of the year

Bullets and buckets from the sky, a wildfire threatening a historic town and extreme heat records broken above the Arctic Circle.

These are just some of the top weather stories Environment and Climate Change Canada has included in its list this year, which saw seemingly every coast affected by some form of extreme or unusual weather.

Alberta hailstorm in August 

One of the most dramatic — and damaging — events this year was an end-of-summer thunderstorm that struck hard and fast. Residents in Calgary and surrounding areas shared photos and videos of shattered windshields and dented roofs.

Summer flooding in Ontario 

Heavy July downpours turned a major artery into the city of Toronto into a pool — twice in one week. The next month, nearby Mississauga saw flash flooding and rain that had fire crews rescuing dozens of people.

The shock exposed infrastructure gaps, with experts saying that climate change's unpredictability means cities can't rely on past records to build future systems.

Jasper's July wildfires

Nestled in the heart of natural forest beauty, the people of Jasper, Alta., had very little notice in late July to get out of the way of fast-moving wildfires.

By the time the smoke cleared, one-third of the town was destroyed. The national park saw more than 32,000 hectares burned — the worst in more than a century.

Atmospheric rivers in British Columbia 

The most recent on ECCC's list were the atmospheric rivers that parked over British Columbia in September and October. The latter, so intense, it killed two motorists on Vancouver Island and an elementary school teacher in Coquitlam.

The mid-October event dumped as much as 300 millimeters of rain in some parts of B.C. over a couple of days.

The duality of June 19

Two extremes hit two regions of Canada on the same day: June 19. The East baked — and set more than 100 new daily temperature records.

But in the West, Alberta set 13 records for low temperatures, with Hendrickson Creek (about 150 kilometres north of Jasper) recording a new daily minimum record of -2.7 C.

Scientists with Environment Canada say this summer see-saw is normal, but the record setting extremes were not.

Arctic heat waves 

Canada's North is warming four times faster than the rest of the world, and this summer, people saw daily temperature records broken.

In Inuvik, N.W.T., more than 200 kilometres north of the Arctic Circle, temperatures in early August were well above 30 C — with a peak of 34.8 C on Aug. 7, the highest temperature ever recorded there.

"With nearly constant daylight, nighttime temperatures barely dropped, hovering at 27 degrees at midnight," said Jennifer Smith, National Warning Preparedness Meteorologist at Environment and Climate Change Canada, in a news briefing today.
