Otter 405 was delivered to the RCAF on 20th December 1960 with serial 9423. It was allocated to No.6 Repair Depot as a spare and put into storage at the Dunnville, Ontario depot. On 18th October 1961 it was assigned to 438 Squadron at St.Hubert, near Montréal. It suffered minor damage on 9th July 1962 at Winnipeg on a cross country training flight. The following month, 9423 was selected for duty with 116 Air Transport Unit (ATU), supporting a United Nations mission in New Guinea, and was flown to Trenton to be prepared for deployment. It would accompany 9424 (407). Both of these Otters were provided with amphibious floats and painted all white with large UN titles. They were loaded on board RCAF Hercules and departing on 30th August 1962 flown to Biak, New Guinea where they were re-assembled and entered service with 116 ATU. On 31st January 1963 9423 received minor damage to the port float when a truck reversed into it, but that was repaired. On 27th April 1963 the two Otters were again loaded into RCAF Hercules for the long trip home. Both were flown to Calgary, arriving on 8th May 1963, where they were put into storage at the Canadian Pacific Airlines depot at Lincoln Park.

In January 1964, 9423 was transferred from Lincoln Park to Saskatoon and remained in storage there until 11th March 1964, when it went to 6 Repair Depot, Dunnville for repaint and to be prepared again for RCAF service. On 24th April 1964 it re-joined 438 Squadron at St.Hubert. Its service  with the unit however was short as the following year, in September 1965, it was again selected for UN duty, this time with 117 ATU in Kashmir. Also selected for this duty were 9406 (365) and 9422 (404). These three Otters were flown by RCAF Hercules to Lahore in Pakistan, 9423 being the first to arrive on 5th October 1965. The three Otters were returned to Canada in early April 1966, to 6  Repair Depot, Trenton, to be prepared to return to RCAF service. On 4th May 1966, 9423 was assigned to 102 Communications Unit at Trenton and on 24th August '66 to 4 Operational Training Unit (OTU), also at Trenton. In July 1968, 4 OTU was re-designated 424 Squadron at Trenton and 9423 flew for the Squadron until damaged in an accident on 23rd May 1969, a 'B' category crash in the course of a training detail.

During a handling test, the student was briefed that the next take-off from water would be a cross- wind take-off followed by a cross-wind landing. With climb flap set and airspeed at 65 knots, the throttle was retarded to simulate an engine failure. The student then depressed the nose and commenced a turn into wind. The instructor realized that a turn from 300 feet could not be safely completed and attempted to apply power. The engine did not respond immediately and a heavy landing resulted. The Otter was taxied to the shore and beached. 9423 was taken the following month to the Mountain View depot, where it was repaired by 6 RD. On 9th July 1971, after a period of storage following the repairs, it was assigned to 400 Squadron at Downsview, also used by 411 Squadron.

While based at Downsview, as well as local duties, 9423 made a number of long-range trips, including several to the Arctic. The 411 Squadron history shows a fine photograph of 9423 on amphibious floats flying over Fort Prince of Wales at Churchill. The following month, from 13 to 15th August 1973, it made a trip from Downsview-Sioux Lookout-Fort Albany (searching the Albany River and portage points for a canoe expedition)-Moosonee-North Bay-Downsview. In the summer of 1977, 9423 accompanied by 9415 (393) flew up to Spence Bay to provide re-supply for Army engineers who were building a new runway. A Hercules or Buffalo would deliver supplies to Shepherd Bay and the Otters would in term deliver the supplies to Spence Bay.

9423 continued in service with 400 Squadron until 8th October 1981 when it was ferried to the Mountain View depot and put into storage. It was put up for disposal through the Crown Assets Disposal Corporation, one of several Otters to be sold at auction in February 1982, advertised for sale with total airframe hours of 5,874. The purchaser of the Otter was Nahanni Air Services Ltd of Norman Wells, Northwest Territories to whom the Otter was registered C-GUTW in February 1983. Nahanni Air Services had also purchased two other ex-Canadian military Otters 9406 (365) which became C-GUTL and 9421 (402) which became C-GUTQ. A company in Colombia agreed to purchase all three Otters from Nahanni Air Services. The proposed purchaser had the exotic name of Aerolineas de la Orinoquia & Amazonia Limitada and early in 1984 paid a deposit and obtained Colombian registrations for the three aircraft. C-GUTW (405) was to become HK-3050X. The three Otters were made ready for delivery but the final payment was never made and nothing further was heard from the would-be purchaser.

After the sale to Colombia fell through, C-GUTW went on lease to Goose Bay Air Services Ltd., based at Goose Bay, Labrador in June 1984. In July 1986 it was sold, and registered to Nakina Outpost Camps & Air Service of Nakina, Ontario and flew for that company until sold to Harbour Air Ltd., of Vancouver. It arrived in Vancouver on delivery on 6th June 1991 and was put into service. An incident was recorded on 26th September 1991 at Vancouver River. While cruising at 2,500 feet, the number one cylinder head cracked. Engine oil created smoke, some of which drifted into the cockpit but the Otter returned safely to base. During the winter of 1991 /1992, UTW was converted to a Vazar turbine by Harbour Air at their Vancouver hangar and then joined their fleet of turbine Otters on the company's scheduled service. As at September 1999, its total airframe time had risen to 16,148 hours. It is still in service as part of the Harbour Air fleet.
