The city's economy slumped after the war, although reconstruction from the Halifax Explosion brought new housing and infrastructure as well as the establishment of the Halifax Shipyard.
However, a tremendous drop in worldwide shipping following the war as well as the failure of regional industries in the 1920s brought hard-times to the city, further aggravated by the Great Depression in 1929.
One bright spot was the completion of Ocean Terminals and the Pier 21 immigration complex in the city's south end, a large modern complex to trans-ship freight and passengers from steamships to railways.
The harbour's strategic location made the city the base for the famous and successful salvage tug Foundation Franklin which brought lucrative salvage jobs to the city in the 1930s.
While a military airport had been in operation at Dartmouth's Shearwater base since World War I, the city opened its first civilian airport in the city's West End at Chebucto Field in 1931.
Pan-Am began international flights from Boston in 1932.

War Plan Red, a military strategy developed by the United States Army during the mid-1920s and officially withdrawn in 1939, involved an occupation of Halifax by US forces following a poison gas first strike, to deny the British a major naval base and cut links between Britain and Canada.
