The CAR was merged into the Grand Trunk on 27 Mary 1914 and the subsidiary company's name started to disappear as the Grand Trunk's timetables and equipment started to usurp those of the former subsidiary. Despite further Grand Trunk investments in the former CAR infrastructure, including new depot facilities, improved roadbeds and heavier track, the increased freight tonnage, passengers and income did not keep pace with the more rapidly increasing costs, so that net losses increased year by year. After the First World War, the bankrupt (or near-bankrupt) Grand Trunk Railway was finally taken over in 1923 and absorbed into the new government-owned Canadian National Railway, which also took over ownership of the former Canada Atlantic properties.
