The Canadian Coast Guard (CCG) maintains a fleet of Cape-class motor lifeboats based on a motor lifeboat design used by the United States Coast Guard. In September 2009 the CCG announced plans to add five new lifeboats, bringing the total number of Cape-class lifeboats to 36.

The vessels are staffed by a crew of four, two of whom are rescue specialists. In spite of its name, the CCGS Cape Roger is a larger patrol vessel, not a Cape-class lifeboat. The CCG also maintains some larger motor lifeboats based on Arun-class lifeboats designed in the United Kingdom. In 2021 a contract was awarded to Ocean Pacific Marine to upgrade the class over a 7 year period.
