After Confederation, boosters of Halifax expected federal help to make the city's natural harbor Canada's official winter port and a gateway for trade with Europe. Halifax's advantages included its location just off the Great Circle route made it the closest to Europe of any mainland North American port. But the new Intercolonial Railway (ICR) took an indirect, southerly route for military and political reasons, and the national government made little effort to promote Halifax as Canada's winter port. Ignoring appeals to nationalism and the ICR's own attempts to promote traffic to Halifax, most Canadian exporters sent their wares by train though Boston or Portland. No one was interested in financing the large-scale port facilities Halifax lacked. It took the First World War to at last boost Halifax's harbor into prominence on the North Atlantic.
