About Aethra

CCGS Sir Humphrey Gilbert is a former Canadian Coast Guard light icebreaker and buoy tender that was later sold to a private owner and renamed Polar Prince. The ship entered service with the Department of Transport Marine Service in 1959 and transferred to the newly created Canadian Coast Guard in 1962, active until 2001. The icebreaker was sold to private interests in Newfoundland and renamed Polar Prince, sitting mostly idle until resold in 2009 to GTX Technology Canada Limited for service in the Arctic Ocean as a commercial icebreaker. In 2017, the vessel was temporarily rechristened Canada C3 and used for a high-profile voyage around Canada's three maritime coasts as part of the nation's 150th anniversary. In November 2021, the ship was purchased by Miawpukek Horizon Maritime Service Ltd, a joint venture between Horizon Maritime and the Miawpukek First Nation and chartered for educational and research expedition use.
