in Mont-Laurier and the popular tourist village of Mont-Tremblant in the Upper Laurentians. The cities of Ottawa and Gatineau were brushed by the storm but escaped the worst of the effects. Southern Quebec During the rest of the late evening, the storm weakened as it travelled through southern Quebec and eastern Ontario, but still brought lightning to the Laurentians north of Montreal. The following day, the remnants of the derecho reformed over parts of New England, including Maine, with effects less severe than the original cluster. Aftermath As a result of the storm at least one person died in the Algonquin Park region while another person was severely injured by a fallen tree. Other injuries occurred in many areas hit by the storms. Two people were briefly missing at the La Vérendrye Wildlife Reserve northwest of Maniwaki, Quebec during the height of the storm. Hydro One in Ontario reported that over 170,000 customers were left without power in the northeast part of the province and that 90% of the city of North Bay lost power. All of Manitoulin Island was without power. Many others areas including the Sudbury area and the Upper Ottawa Valley towns of Pembroke, Mattawa and Petawawa also had major power outages. Major outages were reported in several areas in Quebec particularly in the Outaouais region. Hydro-Québec estimated that 145,000 of their customers lost power but separate storms in the areas around Rouyn-Noranda, Val-d'Or, Montreal, Trois-Rivières and Quebec City contributed to some of the outages. 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. Later that evening a powerful cool front crossed southern Ontario causing further storm damage in Ontario (see below).
