Origins
Canada was among the first countries to implement telephone service using a
In 1952, the
First links
With Bell as the only remaining contender for the CBC network, plans began for the first major link from Toronto to Montreal via Ottawa. After discussions between Bell's president Thomas Wardrope Eadie and CBC's president Alphonse Ouimet, the network would also include a link to Buffalo, New York, to allow US television programming to be rebroadcast into the Toronto market.[6]
The link went live on 15 January 1953, and the rest of the network to Montreal was completed in May the same year. The network was extended to

The network used the
Cross-country expansion
The first links in Ontario and Quebec were within areas served entirely by Bell, but this was not the case for the rest of the network, where smaller regional telephone companies held local monopolies. This required additional planning, including deciding how to split up the costs and revenues. This was carried out within the
Construction of the cross-country network began on 8 March 1955. The system required a total of 139 stations, spaced at an average of 25 miles (40 km). The stations in the original core typically used squared-off

SaskTel was the first regional carrier to complete their assigned section of the system, which went operational in 1957. The entire system carried its first signals on 18 June 1958, and was declared officially operational on 1 July, Dominion Day.[7] Stretching 6,400 km from Sydney, Nova Scotia to Victoria, British Columbia, it was the longest microwave relay in the world.[6][7]
It was further extended to
The first television program played coast-to-coast was "Memo to Champlain", broadcast on Dominion Day. Among the many programs the network enabled was Hockey Night in Canada[9] and a famous event held by CBC where people from across the country joined on television to sing Christmas carols live.[14] It took just 20 milliseconds for a microwave signal to travel from one coast to the other.[12]
Continued improvement
During the 1950s, CNCP concentrated on building a network in the more highly populated section of Canada, mostly in the area between Montreal and Toronto. This changed in 1962 when the CNCP received a contract from the
CNCP opened their new system between Montreal and
As traffic on the original network grew, Bell carried through on their own plans and built a second Skyway using the same TH system as the CNCP lines.
Demise
The seeds of the demise of the network appeared in 1972 with the launch of
The network remained in use for both data and voice, undergoing numerous upgrades to keep it effective in the era of satellites. This came to an end with the introduction of the first effective long-distance
