MONTREAL (Reuters) - A regional commuter plane crashed in central Canada on Tuesday, killing four of the 17 people on board, police said. The Brazilian-made Embraer EMB-110 turboprop aircraft owned by Manitoba-based Sowind Air Ltd. went down in freezing rain near the airport of Little Grand Rapids, an isolated aboriginal community of 900 people 186 miles (300 km) northeast of Winnipeg, the capital of Manitoba province. The Royal Canadian Mounted Police said three people died at the crash scene. Two critically injured adults and a child were airlifted in a small plane to Winnipeg's Health Sciences Center for treatment. "Unfortunately, we were not able to resuscitate the child and he was pronounced dead shortly before 10 p.m. (11 p.m. EST) (0400 GMT)," Jim Rodger, spokesman for the Health Sciences Center, told Reuters. Rodger said the two adults remained in critical condition. Other survivors had less severe injuries and were being treated at a small nursing station in Little Grand Rapids, but officials could not provide further details. Local residents had rushed to the crash scene in dense bush on snowmobiles to help the injured. Weather plagued rescue efforts throughout the afternoon and evening. A Canadian Armed Forces Hercules transport plane carrying search and rescue technicians was unable to land at the community's airstrip because of fog and freezing drizzle. The twin-engine plane went down in bad weather at about 3:30 p.m. local time (1630 EST) (2130 GMT) while trying to land, crashing in the bush about 328 feet (100 metres) short of the runway, officials said. The flight originated at the St. Andrews airport outside Winnipeg and was destined for Little Grand Rapids. Little Grand Rapids is accessible only by air for most of the year. In the winter, it can be reached by snowmobile or overland ice-roads.
