On October 31, 2007, all shares in Loral Skynet were transferred to Telesat through a contract worth 3.25 billion Canadian dollars , thus merging them into one provider. Telesat is a company whose main shareholders by the Treaties indirectly the Canadian Public Sector Pension Investment Board and Loral Space & Communications Inc are.
Telesat launched the Anik A1 satellite, the first state communications satellite, into geosynchronous orbit in 1972 . In 1978 the first satellite to transmit in the Ku-band was launched and in 1981 two satellites were brought to a common geostationary position for the first time. Since 1996 the company has been offering internet services via satellite.
The company supplies signals from Canada's two most important DBS providers: Bell ExpressVu and StarChoice , as well as more than 200 Canadian television stations.

LEO constellation
Telesat plant also the operation of a constellation of communication satellites in low earth orbit (engl. Low Earth Orbit LEO), similar to the Starlink system of SpaceX , but much smaller, about 300 satellite. A first test satellite names LEO Vantage 1 was established in January 2018 a Rideshare -Flight on an Indian PSLV launch rocket. With the commissioning of this satellite, Telesat secured the radio frequencies already reserved for the planned satellite network.
Construction of the actual constellation is slated to begin with the launch of 78 satellites into polar orbits in 2022. In the same year, it should be possible to use the system in high northern latitudes . 200 more satellites should enable a global offer from 2023 . Telesat signed contracts with the US companies Blue Origin and Relativity Space for several launches each with the New Glenn and Terran 1 rockets, which are still in development .
