In  June 1945, U-190 surrendered at Bay Bulls, Newfoundland, and was officially commissioned into the Royal Canadian Navy. The ship was piloted from Bay Bulls by RCN Lt. Peter Woods who resides in Halifax to this date.

One of U-190's first duties as a vessel of the Royal Canadian Navy was to undertake, in the summer of 1945, a ceremonial tour of communities along the St. Lawrence River and Gulf of St. Lawrence, with stops in Montreal, Trois Riviéres, Quebec City, Gaspé, Pictou, and Sydney. Back in Halifax it commenced duties as an anti-submarine training vessel, which role it continued to fulfill until 24 July 1947. On October 1947, U-190 was at last sent to the bottom during Operation Scuttled.

Michael Hadley, in his book entitled "U-Boats Against Canada" described the end of the U190 this way:

"Operation Scuttled" marked paid to U-190s account. Touted on two occasions in the press as an exercise designed to train inexperienced post-war recruits in the art of combined operations, it was in fact a final touch of rather raffish theatre. Painted in bright red and yellow longitudinal stripes, U-190 was towed to the spot where the sub had sunk HMCS Esquimalt, and where at precisely 1100 hours on 21 October 1947 the tradition bound RCN intended to celebrate Nelson's "glorious" Trafalgar Day victory over  the French fleet in 1805 by pounding the empty hulk into the depths. While the hapless "enemy" drifted, the "friendly" forces gathered for the kill: Tribal Class destroyers HMCS Nootka , HMCS Haida and the Algerine minesweeper New Kiskeard.

The Naval Air Arm provided a collection of "string bag" aircraft: eight Seafires, eight Fireflies, two Ansons, and two Swordfish. The scenario, staged for twenty four representatives of press and radio, called for a carefully choreographed sequence of battle escalating from airborne rocket attack to the grand finale of destroyer bombardment with 4.7 inch guns and a death blow with Hedgehog. The RCN's final sally against a German U-Boat ended on much the same comic operatic note as its first foray against suspected invaders off Quebec City in 1939 .... Almost before the ships had a chance to enter the act, U-190 pointed its bows into the air after the first rocket attack and slipped silently beneath the sea - just 19 minutes after "Operation Scuttled" had begun.

The hulk of U-190 lies on the ocean floor somewhere near the hulk of its former prey, HMCS Esquimalt. A fitting end to the story..
