The Grand Trunk Pacific Railway (reporting mark GTP) was a historic Canadian transcontinental railway running from Fort William, Ontario (now Thunder Bay) to Prince Rupert, British Columbia, a Pacific coast port. East of Winnipeg the line continued as the National Transcontinental Railway (NTR), running across northern Ontario and Quebec, crossing the St. Lawrence River at Quebec City and ending at Moncton, New Brunswick. The Grand Trunk Railway (GTR) managed and operated the entire line.

Largely constructed 1907–14, the GTPR operated 1914–19, prior to nationalization as the Canadian National Railway (CNR). Despite poor decision-making by the various levels of government and the railway management, the GTPR established local employment opportunities, a telegraph service, and freight, passenger and mail transportation.[1]

The CNoR tracklaying through the Canadian Rockies in 1913 roughly paralleled the GTPR line of 1911 and created about 100 miles of duplication. In 1917, a contingent from the Corps of Canadian Railway Troops added several crossovers to amalgamate the tracks into a single line along the preferred grade as far west as Red Pass Junction, which is misidentified as 36 miles west of Red Pass on Google Maps. The surplus rails were lifted and the heavier grade GTPR ones shipped to France for use during World War I.
In 1915, unable to meet its debts, the GTP asked the federal government to take over the GTPR.[46] The CNoR was in worse financial shape.[53][54] The royal commission that considered the issue in 1916 released its findings in 1917.[55] In March 1919, after the GTPR has defaulted on construction loans to the federal government, the federal Department of Railways and Canals effectively took control of the GTPR[56] before it was merged into the CNR in July 1920. Noting numerous construction blunders, the 1921 arbitration on worth also ranked its significance within the naïve railway schemes of that era by this observation: “It would be difficult to imagine a more misconceived project.”[57] The GTP itself was nationalized in 1922.[58]

It has already been described how the importance of the Jasper area as a transcontinental route deteriorated after the decision was made to build the Canadian Pacific Railway through another pass further south. But during the last few years of the nineteenth century, once the Canadian Pacific Railway was constructed, certain businessmen and politicians became convinced of the need for an alternative trans- continental railway line, following a more northerly route across the prairies. The advantages to railroads of the Yellowhead over the other passes through the Rockies were well known, and just after the turn of the century the Grank Trunk Pacific project was begun. However, it was to be another decade before steel reached the new national park which had been established along the right-of-way.

The National Transcontinental Railway Act became law near the end of 1903, representing an agreement between the Ministry of Railways and Canals and the newly incorporated Grand Trunk Pacific Railway Company for the construction of a railway from Moncton, New Brunswick, to the Pacific Coast. The early plans for the western line, developed in 1902, were to follow the route from Edmonton to the coast through the Yellowhead Pass, along the original Sandford Fleming survey.
