There has been only one vessel named Corner Brook in the Royal Canadian Navy.

HMCS Corner Brook (878)

On 6 April 1998, the Canadian Government announced its decision to acquire the four Upholder Class submarines from the United Kingdom, which had been placed in reserve by the Royal Navy when it switched to an all-nuclear submarine fleet in the early 1990s. All boats were re-named and the class designator was changed from Upholder to Victoria.

Operationally, Canadian Forces submarines are a specialized element of Canada’s maritime forces. They directly contribute to Canadian security and national defence through their ability to undertake lengthy covert patrols in Canadian maritime areas of responsibility and more distant waters. Such patrols frequently involve operations with national or allied forces or in support of Other Government Departments. In addition to operations, Victoria Class submarines participate in national and international naval exercises in which a variety of patrol and war-fighting skills are honed to a high level of perfection. In times of tension or conflict Victoria Class submarines, armed with heavyweight torpedoes, are powerful tools of coercion and dissuasion able to operate in waters adjacent to Canada or globally.

Formerly HMS Ursula, HMCS Corner Brook was accepted by Canada in February 2003 after her re-activation in the United Kingdom. She was commissioned as HMCS Corner Brook on 29 June 2003 in her namesake city and then transited to Halifax, Nova Scotia, where she underwent a modernization that featured installation of equipment optimized for Canadian naval operations. Since 2006 she has undertaken a busy programme of exercises and operations. Notable activities have included a deployment to European waters, a Canadian sovereignty patrol in northern waters, and an operational deployment to the Caribbean. On 23 May 2008, the Chief of Defence Staff presented HMCS Corner Brook with a unit commendation. The award was for the particular breadth of operations the boat was able to plan for and successfully carry out during her European deployment, Arctic sovereignty mission, international and domestic exercises and her Caribbean deployment. Currently, Corner Brook is completing the first of two work periods that will see her sea-going capability extended until the middle of 2011, at which time she enters a two-year maintenance refit. She is scheduled to conduct further exercises and operations throughout the first half of 2009 and for the entirety of 2010.
