Capital of Nova Scotia, Canada, on the eastern shore of the province; population (2001 est) 359,100. Halifax is situated on a fortified height (the 18th-century Halifax Citadel, which has become Citadel Hill Museum). The harbour mouth has two entrances, formed by McNab's Island, and is connected by a narrow channel with Bedford Basin in the north.

It is the Atlantic terminus of the Canadian National Railway and is served by a branch of the Canadian Pacific Railway. Halifax is the eastern terminus of a transcontinental railway.

The 19th-century Shubenacadie Canal links Halifax to the Bay of Fundy across the Nova Scotia Peninsula. The opening of a container terminal in 1970 made shipment via Halifax one of the quickest routes for freight from Europe to central Canada because of the easy transfer between ships and trains. The port of Halifax became so busy that a second container terminal was opened in 1981.

It is the largest and most important city of the Canadian Maritime Provinces (consisting of Nova Scotia, Prince Edward Island, and New Brunswick), and is the main port in eastern Canada; industries include oil refining, food processing, and aerospace.

Halifax harbour is ice-free all year round, due to the warm Gulf Stream current. There are six military bases located here, and the city is a centre for oceanography.
