Environment Canada has confirmed a second tornado touched down during fierce thunderstorms that swept through Ontario's Muskoka region Friday evening.
The agency says it sent an expert to Huntsville on Saturday on the strength of eyewitness reports of a twister and images of damage to trees and buildings.
Environment Canada confirms the first tornado was an EF-1 tornado. That tornado touched down south of Huntsville and moved for 3km north across Fairy Lake, ending at the Deerhurst resort.
The second tornado was stronger, touching down about 15 km north-east of Huntsville. It was on the ground for about 9 km, with wind speeds of up to 190 km per hour. That tornado has been classified as an EF-2 tornado.
Both twisters downed trees and powerlines.
The winds also knocked out power to roughly 13,000 Hydro One customers in the area Friday night.
Environment Canada staff say they estimate 80 to 90 per cent of the forest near where the second tornado touched down has been destroyed.
