This booklet seems to have been issued solely to extoll the virtues of socialized railroading. While the Canadian Pacific had received capital subsidies, it was operationally profitable. After it was built, the Canadian government continued to subsidize new rail construction, including the Grand Trunk Pacific, Canadian Northern, and Intercolonial. None of these were operationally profitable, so between 1918 and 1923 they were combined into the government-subsidized Canadian National Railways.
While this booklet isn’t dated, a map in the back is dated November 11, 1949, and the most recent data cited in the booklet is from 1949. So the booklet itself must have been published in 1950. Photos show steam-powered passenger trains and Diesel-powered freight trains along with hotels, steamships, and telecommunications centers.
The booklet noted that, “Much of the mileage is at present unprofitable for the C.N.R., but is maintained as a necessity in the national economy.” “Necessity” is always liberally interpreted by politicians. As Wikipedia observes, “The result of various governments using CNR as a vehicle for various social and economic policies was a subsidization running into billions of dollars over successive decades.” After shedding many of its branch lines, however, CN became mostly profitable after 1978 and was privatized in 1995.
