Part of their recent work has involved the updating of the CANTAT transatlantic cable system that connects the United Kingdom and Newfoundland under the Atlantic Ocean.
After the 1984 election, Prime Minister Brian Mulroney began the process of privatizing Crown corporations and Teleglobe Canada was one of the target assets.
It was finally sold to a small telecommunications equipment maker Memotec Data Incorporated of Montreal in 1987 and Teleglobe Canada became a unit of its new owners.
Renamed again, it became Teleglobe International Holdings Limited with incorporation in Bermuda and its corporate office in Virginia.
During its life as a Crown corporation and as part of Memotec Data, Teleglobe still maintained operations in Canada.
