Otter 432 was delivered on 9th October 1962 to Demerara Bauxite Company Ltd., registered CF- OTX. This company was a subsidiary of the Aluminium Company of Canada, and had established a major presence in the South American country of British Guiana, later called Guyana. Bauxite had been discovered in Guyana in a belt stretching across the country from the North West district to the Corentyne River, with large deposits identified in the Pomeroon, the Essequibo, Mackenzie, Ituni, Canje and Orealla Districts. The Demerara Bauxite Company had established processing and shipping facilities at Mackenzie, the head of ocean navigation in the Demerara River, where it also had a mine. From there, the bauxite was shipped as raw ore to the parent company's plants in Canada and the United States.

Otter 432, an amphibian, was acquired to service the company's operations in British Guiana and was shipped to its base at Mackenzie, re-assembled and entered service. DHC technical representatives travelled to Mackenzie in connection with its Certificate of Airworthiness renewals. By 11th December 1965 it had 1,560 hours on the airframe. It continued in use by the Demerara Bauxite Company for the next few years. In May 1968 it was leased to Terra Surveys Ltd., for a few months, for geological survey work in Guyana. The Demerara Bauxite Company continued to have first call on the Otter if they needed it, and their pilot flew it while it was on lease to Terra Surveys. Its use in South America came to an end in March 1969 when it was sold to Bradley Air Services Ltd., and flown back to Canada.

It was overhauled at the Bradley base at Carp, Ontario during April / May 1969, at which stage it had 3,189 hours on the airframe, after six and half years service in Guyana. It was registered to Bradley Air Services Ltd on 12th May 1969. In between service with Bradley it was leased out to other operators from time to time. In December 1969 it was leased to Austin Airways, based at Timmins, Ontario for a few months. In April 1971 it was leased to Laurentian Air Services, based at Schefferville, Quebec for a few months, before reverting to service with Bradley, with whom it continued in use until an accident on 24th September 1974. The Otter was on a ferry flight from Frobisher Bay, Northwest Territories back to Ottawa. It suffered engine failure in the cruise and made a forced landing thirty miles north-east of Lac Nichiquan in the remote Gagnon region of Quebec. It was badly damaged in the forced landing on rough terrain, and would never fly again. Its total time at the date of the accident had risen to 6,780 hours.

After lying out in the bush at the accident site for some time, OTX was retrieved and brought back to the Bradley maintenance base at Carp, near Ottawa. Also at Carp was a damaged Otter, number 113, tail number 53267. Bradley had purchased this damaged Otter from the USAF after it had crashed at Goose Bay, Labrador in May 1974. Bradley rebuilt number 113, using salvageable parts from OTX. This work was completed in August 1976 and Otter 113 was then registered to Bradley Air Services as C-GPHD, and the registration CF-OTX was cancelled.
