Two of the five cars hit a house on Old Weston Road near Rockwell Avenue, according to Toronto Fire District Chief Stephan Powell. Emergency crews were called to the scene at approximately 9:20 a.m The driver of one of the vehicles fled on foot and police are searching for the person. No one at the scene was injured. Police do not know if the hit-and-run driver was injured. Up to seven homes were initially evacuated after the leak, but Enbridge Gas shut off the gas at 10:45 a.m. Residents in all but one of the homes have been allowed to return, Powell said. The remaining house is the one that was hit by the cars. One of the cars in the crash hit a gas line and the gas was escaping quickly, he added. “For safety reasons, after monitoring the air, we began evacuating homes on either side of the affected property,” Powell said. A side entrance of the home that was hit was deemed unsafe, he added. Structural engineers from the City of Toronto are expected at the site later Sunday. This vehicle was involved in the accident on Old Weston Road on Sunday. (Dave Hill/CBC) Krista Luxton, a spokeswoman for Enbridge Gas Inc., said an operations supervisor was heading to the scene at about 1:30 p.m. of Sunday to develop a repair plan. Luxton said the gas meter was attached to the porch of the home, which was damaged in the crash. The porch must be repaired before the gas can be turned back on, he said. Only the affected home is without gas service, he added. “In terms of natural gas, the area has become safe. There is no gas blowing, no gas leaking,” he said. “There is no danger at this time.” Enbridge Gas repair crews had to dig into the pavement to reach the pipe to shut off the gas, he added. Const. David Hopkinson, a spokesman for the Toronto Police Service, said callers told police they smelled gas after the crash. Police have cordoned off the area to secure the scene and allow officers to investigate the crash.
