CCGS Terry Fox is a Canadian Coast Guard Heavy Gulf (and Arctic) icebreaker. Named after the late cancer research activist Terry Fox, the vessel was built in 1983 as MV Terry Fox by Burrard Yarrows Corporation in Vancouver, British Columbia. Terry Fox, along with her sister ship MV Arctic Kalvik supported Gulf Oil's operations in the Beaufort Sea during the 1980s. Not limited to escorting tankers through ice, these multipurpose ships were designed to act as heavy tugs and supply vessels to support offshore oil rig platforms in a hostile environment.
