Strong winds uprooted trees and damaged homes, but nobody was injured when a tornado touched down in the Ottawa area Sunday evening. Environment Canada issued tornado warnings in eastern Ontario and western Quebec after someone spotted a twister near the Gatineau Airport just before 6 p.m. The warning, came amid a small but powerful storm that brought damaging winds, hail and intense rainfall. Debris closed several streets, including a major highway, but the city said they had all reopened by about 9 p.m. The capital region was hit by several tornadoes less than a year ago, which flattened neighbourhoods and did severe damage to the power grid. The city is still in a state of emergency over floods earlier this spring. Many residents stopped to take pictures and videos of the tornado as it formed over the city.
