Niagara Helicopters was started back in the 70s primarily as a flight school based in Metcalfe, Ontario. The outfit used Enstroms for training in the off season. During the tourist season the helicopters were used for sightseeing at the Falls and the school employed its graduates as pilots. This worked out very well and to the best of my knowledge they never had an accident.
In 1982 the owner was killed in an un-aviation related accident. His father was not interested in keeping the business and sold it for a very good price, minus the hardware, to the present owner who never looked back. So the company went from a small operation with a handful of small helicopters to the present sophisticated operation using 407s.
