 Final damage assessments from this destructive storm are unlikely ever to be fully known, in part because of the remoteness of large portions of the affected area.The precise injury count and death toll are also uncertain, again due to inaccessibility to parts of the region, especially with trees blocking so many remote roads.Environment Canada investigated areas with heavy damage to ascertain whether tornadoes touched down, particularly on the Manitoulin Island and in Larder Lake, near Kirkland Lake but, at this stage, almost all damage reports are straight-line in nature and radar imagery favours a classic 'progressive derecho storm' with winds of up to and possibly exceeding 200 km/h (120 mph) at its peak, possibly with embedded tornadoes.
