CCGS C.P. Edwards was a Canadian Coast Guard ship. Entering into service as a coastal freighter in 1946 with the name Ottawa Mayhill, it was commissioned in 1947 as CGS C.P. Edwards for the Department of Transport's Marine Service, serving as a light vessel. C.P. Edwards was transferred into the newly created Canadian Coast Guard in 1962, and was decommissioned in 1972. The vessel was sold to private interests that year. An engine was acquired by Canadian Science and Technology Museum in 1976. The Canadian registry of the vessel was closed in 1979 and the ship was sold to U.S. interests.
