Environment Canada says Ontario has its first confirmed tornado of the 2014 season.
An Environment Canada survey team investigated wind damage from severe thunderstorms that roared across the Mildmay area southwest of Owen Sound on Tuesday afternoon.
The team confirmed that wind damage was likely caused by a low end tornado with estimated wind speeds near 150 km/h.
The tornado caused a west to east damage path about two kilometres long and up to 150 metres wide close to Mildmay.
One house suffered significant damage, while two barns were also damaged, along with trees and hydro poles.
