posts were. Provoked by a prolonged tax dispute with Port Arthur and its seizure of a locomotive in 1889, the CPR relocated all its employees and facilities to Fort William. The collapse of silver mining after 1890 undermined the economy of Port Arthur. It had an economic depression, while Fort William thrived.
The 20th century
In the era of Sir Wilfrid Laurier, Thunder Bay began a period of extraordinary growth, based on improved access to markets via the transcontinental railway and development of the western wheat boom. The CPR double-tracked its Winnipeg–Thunder Bay line. The Canadian Northern Railway established facilities at Port Arthur. The Grand Trunk Pacific Railway began construction of its facilities at the Fort William Mission in 1905, and the federal government began construction of the National Transcontinental Railway. Grain elevator construction boomed as the volume of grain shipped to Europe increased. Both cities incurred debt to grant bonuses to manufacturing industries. By 1914 the twin cities had modern infrastructures (sewers, safe water supply, street lighting, electric light, etc.) Both Fort William and Port Arthur were proponents of municipal ownership. As early as 1892, Port Arthur built Canada's first municipally owned electric street railway. Both cities spurned Bell Telephone Company of Canada to establish their own municipally owned telephone systems in 1902.
The boom came to an end in 1913–14, aggravated by the outbreak of the First World War. A war-time economy emerged with the making of munitions and shipbuilding. The cities raised men for the 52nd, 94th and 141st Battalions of the Canadian Expeditionary Force.
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
