WINDSOR, Ont. -- Environment Canada says at least one tornado touched down in the Windsor, Ont., area Wednesday night, though the strength of the storm isn't yet known.

Meteorologist Geoff Coulson says there were reports of tornadoes in Windsor and LaSalle, a nearby bedroom community, and it's unclear whether they were one and the same.

He says teams are in the area today to make that determination, gauge the width and the length of the storm's path and get a sense of how powerful the winds were based on the severity of the damage.

Meanwhile, residents and officials are dealing with the aftermath of the storm, which damaged more than a dozen homes and injured four people, though none critically.

In a news conference this morning, Mayor Drew Dilkens said power had been restored to all but approximately 40 properties and public works crews are out clearing debris from roads.

He said about 15 households were displaced by the storm and inspectors are examining the damaged homes to see if and when residents can return.

Dilkens said seeing the destruction in the city's industrial complex and other areas was difficult.

"It's the type of event that you see that happens in other communities, you never anticipate that it would happen in your community. And so when it does happen in your community and you see that level of devastation, it's striking," he said.

Some residents have asked why there was no emergency warning about the storm, the mayor said, adding such a system would only work with advance notice of the storm, which the city did not receive Wednesday night.

The city will look into the possibility of creating such a system for extreme weather and other emergencies, he said.

Environment Canada said an eyewitness saw a tornado near LaSalle, a bedroom community near Windsor, at about 7:10 p.m. ET.

The agency described the storm and tornado Wednesday as a "dangerous and potentially life-threatening situation" before lifting its tornado warning at about 8 p.m.
