A powerful storm in early April that left significant damage in the London, Ont. area is confirmed to be Canada's first tornado of 2017.

Environment Canada launched an investigation following the April 11 storm, in partnership with The University of Western Ontario.

The post-storm investigation, coupled with the university's damage survey, finds that the storm damage is the product of both an EF-1 tornado with peak winds up to 150 kilometres per hour, and downburst winds.

The tornado, which intensified northeast of London, Ont., destroyed a barn roof (pictured above) and tore down trees and hydro poles.

Its path was roughly 11 km long and 200 metres wide.
