Witnesses reported seeing a funnel cloud above the area where the damage occurred. This was one of two tornadoes that occurred on May 26; the other was also an F0 that touched down on Windy Lake.

Figure 1 depicts the surface observations at 2:00 pm EDT, which shows a cold front slicing through central Ontario and a warm front clashing with said front. This frontal interaction would have caused substantial vertical motion, triggering thunderstorms. These thunderstorms would ultimately lead to two F0 tornadoes across Ontario.
