Teleglobe traces its origins back to the formation of Canadian Overseas Telecommunications Corporation in 1950. COTC was a Crown Corporation operating as the exclusive provider of telecommunications services to and from Canada, first by VHF radio, later using newer technologies as they became available.
My best information at this point is that this station was opened in 1966. It became largely obsolete and finally closed in 1995. Today, the property is in private hands, but allegedly for sale for about $250,000.
Although the monster satellite dishes are gone, and with them most of the equipment, this was a fun explore. I even had an opportunity to make some new friends.
