Otter 412 was delivered on 28th March 1962, but was retained by DHC as a demonstrator, registered CF-NWX. It flew for DHC for many years. When it was no longer required as a demonstrator, it remained in use as a test aircraft. There was a proposed sale to the United States in April 1970 and marks N6225 were reserved, but the sale did not proceed and NWX continued in use as a test aircraft, and  also as a company transport. It was often flown by DHC test pilot George A. Neal.

The last trip he recalls flying in NWX was to a lake in Québec with a load of newly hatched fish, to re-stock the lake which senior people in DHC used to entertain customers. The Otter was eventually sold, being acquired by Austin Airways Ltd., of Timmins, Ontario to whom it was registered in November 1978. It was then sold on to Ignace Airways Ltd., of Ignace, Ontario and registered to that company in December 1980. It continued to fly for Ignace Airways until a crash at McKenzie Lake, Ontario on 10th October 1987.

The purpose of the flight on that day was for the captain to check out the co-pilot on the float- equipped Otter. The aircraft, with the two pilots, one passenger and a cargo of sawdust on board was near the maximum take-off weight. It took off for a VFR flight to nearby South Smoothrock Lake. The take-off run and lift off appeared normal. The pilot selected climb flap, reduced engine power and turned to fly along a valley leading away from the lake. The aircraft was at an altitude of 75 to 100 feet and approaching trees near the edge of the lake when it began to lose altitude. The captain applied power but this did not arrest the descent and the aircraft struck the trees and crashed one quarter of a mile from the shoreline. An accumulation of hoar frost on the wing surfaces and downdrafts common in the area led to the aircraft's descent into the trees.

The Otter was taken to Kuby's Aircraft at Kenora, Ontario for a slow rebuild and in May 1992 was registered to Slate Falls Airways (1987) Inc., based at Sioux Lookout, Ontario. In August 1999 the company was reconstituted as Slate Falls Airways (1999) Ltd., and it continued to serve the Ontario bush country from its base at Sioux Lookout. On 18th October 2004 NWX arrived at Fort Frances, Ontario where it underwent conversion over the winter of 2004 / 2005 to a Vazar turbine Otter, the conversion work being performed by Lakeland Aviation.
