Confirmed: Ontario's ninth tornado of 2016

Monday, September 12, 2016, 3:01 PM - Saturday's wicked thunderstorms in eastern Ontario produced the province's ninth confirmed twister of the 2016 season. 

Environment Canada says a thunderstorm in the early evening produced a tornado that began as a waterspout over Lake Ontario before coming ashore at the Hideaway Trailer Park near Bloomfield in Prince Edward County, tracking about 3.5 kilometres to the east before dissipating.

The weather agency says the twister was ranked EF-0 on the Enhanced Fujita Scale, with maximum estimated winds of around 100 km/h. Only Environment Canada can officially confirm a tornado.

Environment Canada says the storm that produced the twister also caused downburst damage, with maximum winds of 90 km/h, to trees and roofs in the area, from Wellington to near Picton.

Saturday's system was intense, with some 17 tornado warnings declared over the course of the evening. Trees were down and some properties were damaged, mostly in the east and the Niagara region, and tens of thousands of Hydro One customers lost power.

Ontario's annual average tornado count is 12, though individual years vary. The province is one of Canada's most tornado-prone, though it has not had a tornado fatality since the Goderich tornado of 2011.

The 1946 Windsor tornado, which killed 17 people, was Ontario's deadliest tornado, and Canada's third deadliest.
