“A dust cloud was seen at the base of the funnel, however, there were no reports of damage,” Environment Canada said. “Therefore, this tornado has been given a preliminary rating of EF0.”

“This was considered a landspout tornado that was generated by weak rotation under rapidly growing clouds or weak thunderstorms,” Environment Canada stated. “Landspout tornadoes do not usually cause significant damage but can still be dangerous as they can topple trees, damage roofs, or toss debris a short distance.”
