Ottawa police say two children were struck by cars while riding two-wheeled vehicles in separate incidents on Wednesday. Police say they responded to the area of West Ridge Drive and Eliza Cresent in Stittsville at approximately 11:19 a.m. after a collision with a vehicle involving a nine-year-old child on a scooter. The child was assessed at the scene by paramedics with non-life threatening injuries, police say. The driver of the vehicle, a man in his 40s, was charged with fail to yield to a pedestrian. A little over an hour later, police responded to a collision between a cyclist and a vehicle in the area of Greenbank Road and Larkin Drive in Barrhaven at 12:35 p.m. Emergency crews attended the scene and assessed a nine-year-old boy for non-life threatening injuries, according to Ottawa paramedics spokesperson Marc-Antoine Deschamps. The boy was taken to hospital in stable condition, he said. The driver was not injured. The crash led to a brief closure at the time of the crash. The collision is still being investigated, police say. The collisions comes less than a day after a woman in her 30s on a bike was critically injured in Stittsville on Sweetnam Drive. Her injuries are considered “life threatening.” A 27-year-old female pedestrian was killed on July 11 after being hit by a pickup truck at the intersection of Elgin Street and Laurier Avenue West.
