Whole swaths of trees were snapped and uprooted as the tornado tracked for 17.2 km through forested areas. Along its path that was 100m wide, falling trees damaged homes and cottages and a boathouse was destroyed. The touchdown occurred at 7:40 pm.

Figure 1 depicts the surface observations at 5:00 pm EDT, which shows a low pressure over Georgian Bay with a cold front stretching into Michigan. This cold front became the focus for intense thunderstorms in the evening hours of August 2nd, which ultimately led to a tornado outbreak across southern Ontario.
