Railway employment was hurt when the federal government took over the National Transcontinental Railway and Lake Superior Division from the Grand Trunk in 1915, and the Canadian Northern Railway in 1918. These were amalgamated with other government-owned railways in 1923 to form the Canadian National Railways. The CNR closed many of the Canadian Northern Railway facilities in Port Arthur. It opened the Neebing yards in Neebing Township in 1922. By 1929, the population of the two cities had recovered to pre-war levels.
