Around 11:30 last night, Warman RCMP notified the public that the Highway 11 northbound lane between the south and north entrances to the Town of Osler was closed following a three-vehicle accident earlier that evening, with detours in place. A collision analyst is investigating. Those are all the details at this point. The Osler Fire Department posted Sunday night on Facebook that the highway is closed. As of noon Monday, there has been no update.
