in the wake of the storm as roadways in the area were blocked by felled trees and power was out throughout the region. The town of Mattawa and rural areas in West Nipissing were particularly hard hit as storage siloes were torn apart, roofs were torn from buildings, utility poles were snapped in two and roads were entirely impassable from the debris strewn across them, in some cases for weeks after the storm. At the same time, the storm affected the Algonquin Park region (mostly the northern portion) and fallen trees killed at least one man from Michigan and injured another, also from Michigan, who were on a canoe trip near Kiosk, a small community located at the northern end of the park. Ottawa Valley, Eastern Ontario and Southwestern Quebec Through the next two hours the storm entered the Upper Ottawa Valley affecting places in Renfrew County such as Barry's Bay, Deep River, Cobden, Petawawa and Pembroke. There were numerous reports of damage, particularly blown-off or damaged roofs. After crossing the Pembroke area, the derecho started to lose some steam. At times, the storm moved at a forward speed of 100–120 km/h (65-75 mph) but had slowed down somewhat when it entered the Pontiac region of western Quebec. Also, the north–south oriented line became more disorganized at its southern end. Still, the storm carried a lot of lightning and damaging wind as it crossed portions of the Outaouais region, the city of Gatineau and extreme northern portions of the city of Ottawa, primarily closer to the Ottawa River, at around 21:00 EDT. Areas such as Chelsea, Cantley, La Peche, Notre-Dame-du-Laus and Kazabazua were hit hard. Spectacular lightning was seen from downtown Ottawa and, when the storm was close enough, some pinkish colour was seen in the northern sky. In the Upper Gatineau north of the National Capital Region, several houses and cottages were damaged and scores of trees were snapped by winds in excess of 90 km/h (55 mph). Five campers were injured by fallen trees, caused by a microburst, while camping in Notre-Dame du Laus. Meanwhile, in the Maniwaki area, a local radio station antenna suffered extensive damage. Northwest of that town in Grand-Remous, several trailers in a park were heavily damaged or destroyed by the force of the winds but no injuries were reported there. Additional damage was reported in the Papineau region further east as well as
