Officials with Environment Canada confirm Saturday night’s storm damage was not caused by a tornado, but instead straight line winds. Severe weather meteorologist Rob Kuhn estimates the winds reached 100 km/hr.

“It looked like a classic downburst, straight line winds coming out of a thunderstorm and the thunderstorm was pretty fast moving in itself.”

Kuhn is part of a damage survey team from Environment Canada. He was called to investigate after receiving multiple reports of a possible tornado touch down.

Kuhn says when doing this kind of search, he looks for distinct patterns in the damage left behind.

“One thing that suggests straight line winds is that all the trees are knocked down the same way.”

According to city of Kitchener’s web page most of the damage occurred in the Strange and Cherry Street areas.

In some locations the heavy winds up rooted trees, tore out air conditioner units from their roof tops and knocked over hydro poles.

Christine Filipowicz lives on Wellington Street in Kitchener, she says while the thurnderstorm scared her, she's thankful no one was hurt. At the time of the storm she was in her bedroom, her son and his friend, upstairs in the attic.

“Suddenly there was a big bang in the wall the front wall and the window just burst into pieces.”

“They just were trying as well to close the front window and the tree fell on - right close to their face."

The storm rolled through the area at around 10:45 p.m. At the height of the storm 6,800 people were left without power.

Vice President of Operations for Kitchener-Wilmot Hydro Wilf Meston said hydro workers have had no rest since last week's big storm.

“We're not even cleaned up from the last weekend storm we've been working all week there’s still a lot of branches and trees that need to be cleaned up.”

The Manager of Engineering for Kitchener-Wilmot Hydro Greig Cameron said, crews were called late last night to restore power to customers.

By 5 a.m. all but 1,200 homes had their power restored. Officials said by 9 a.m. Sunday they expected to have every one back up with full power.

In an email to CTV Kitchener, Cameron said some customers will need to make repairs to their service and get Electrical Safety Authority's connection authorization before they can restore power to their homes.

Meteorologists with Environment Canada say while this was not a tornado, it is not uncommon to see them during the summer months.
