Tornado confirmed in Muskoka

Environment Canada has confirmed that a tornado touched down during fierce thunderstorms that swept through the 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.   

It's too early to know how strong the tornado was, but it damaged several structures.   

The powerful winds also knocked down trees and powerlines, cutting the electricity to 13-thousand Hydro One customers.  

About four-thousand customers were still without power Saturday afternoon.
