Trans Canada Microwave or Trans-Canada Skyway was a microwave system built in the 1950s to carry telephone and TV from Canada's east coast to its west coast. The towers ranged from nine metres high to over 100 metres high in northern Ontario. The system included 139 towers spanning over 6275 kilometres and cost $50 million ($452 million in 2019 dollars).[citation needed]

  • It took just 20 milliseconds for a microwave signal to travel from one coast to the other.[1]
  • The Trans-Canada Microwave system was officially completed on 1 July 1958. It was the longest microwave transmission network in the world in 1958, stretching from Sydney, Nova Scotia to Victoria, British Columbia, placing Canada at the forefront of communications technology.
  • The system was implemented under Bell Canada president Thomas Wardrope Eadie as an all-Canadian microwave network for transporting telephone conversations, Teletype messages and television signals.[2]
