 Several sources ( Lenton , Lynch , Macpherson ) show that in July 1945 Fredericton was transferred to Sydney , Nova Scotia to be decommissioned for disposal and scrapping . Other sources ( uboat.net , Royal Canadian Navy ) claim that a mistake in Lloyd 's Register switched its records with HMCS Saskatoon ( K158 ) . The alternative information shows that Fredericton was sold in 1948 . She was registered under the Panamanian flag as Tra los Montes . In 1950 she was renamed as Olympic Fighter for use as a whaler . Subsequent names included Otori Maru No. 6 in 1956 and Kyo Maru No. 20 in 1961 . The last notation in Lloyd 's Register was for 1978 – 79 .
