John Alexander Macdonald (1815-1891) was the first federal prime minister after the establishment of the dominion of Canada (1867 ~ 1873) and the father of the Canadian Pacific Railway. 1867 after the establishment of the dominion of Canada, the western part is still mostly undeveloped wilderness, and the traffic connecting the eastern and western parts of the mainland is extremely inconvenient. 1869 after the completion of the trans-American Pacific Railway, the voice of Great Colombia (B.C.) appeared to join the United States. 187 1 year, British Columbia joined the Canadian Federation and became an administrative province. It is proposed that the Pacific Railway, which runs through the mainland and can connect British Columbia and Canadian provinces, be the condition of the agreement. Prime Minister MacDonald met their demands. After MacDonald left office, the Pacific Railway project came to a standstill. After many twists and turns, during MacDonald's second term as Prime Minister (1878 ~ 189 1), the Canadian Parliament decided to build the Pacific Railway at 1878. 1in April, 880, the Canadian Pacific Railway started construction. The railway starts from Montreal in the east and extends to Halifax, a port city on the Atlantic coast; It extends westward to Vancouver, with a total length of 3,800 kilometers, and is divided into three sections: East, Middle and West. The western section from the Rocky Mountain to the Pacific coast is very difficult. MacDonald decided to contract the most dangerous western section of the Pacific Railway to Andrew Dunk, an experienced American engineer. Andenko had a good impression on the hard-working and cheap labor force of Chinese workers, and insisted on hiring a large number of Chinese workers, believing that only Chinese workers could be competent. MacDonald strongly advocates hiring China workers who are good at building railways, with low wages and easy management. China workers are more diligent, agile and efficient than white workers, and have won the praise of white engineers. The hardest work in the most dangerous section of the Pacific Railway, such as mountain cutting, stone cutting, foundation laying and filling, is all done by China workers. MacDonald emphasized that "without China workers, there would be no railway". The Canadian Pacific Railway was completed on 1885. On June 28th of the same year, the first train left Montreal for Vancouver. The completion of the railway has played an important role in the development of western Canada, promoting the unification of the autonomous region and economic prosperity.
