Environment Canada says the tornado was rated F1 on the Fujita scale, with peak winds of between 120 and 170 km/h.

Private pilot and Weather Network viewer Jason Dixon sent in pictures of the devastation left by the event, including a shot of a trail of downed trees trees 300 m across at its widest point, and 1.5 km long, that was instrumental in confirming a twister swept through the area.

"The nature of some of the tree damage was consistent with the type of damage that would be caused by a tornado, with some of the trees overlapping as they were uprooted," a report from the agency reads.

The tornado was generated by a severe thunderstorm that passed through the Bread Lake area, 35 km east of Sioux Lookout, in the afternoon and early evening of Monday, June 18.

Environment Canada says they will continue to investigate the area for other possible tornadoes that may have touched down on June 18.

Ontario sees an average 13 tornadoes a year between late April and early October.
