Halifax Harbour - Navigation

Navigation

Halifax's official harbour limit for navigational purposes is delineated by a line running from Herring Cove on the west side of the main channel, to the northern end of McNabs Island, then from McNabs Island across the Eastern Passage to the actual community of Eastern Passage on the east side of the island. The harbour is marked by an extensive network of buoys and lighthouses, starting with Sambro Island Lighthouse at the harbour approaches, the oldest operating lighthouse in North America.

Deep draught vessels must use the main channel into the harbour, which runs on the west side of McNabs Island. The west entrance point marking the beginning of the inner approach using this channel is located near Chebucto Head, approximately 12 kilometres (7 mi) south of the limit.

Shallow draught vessels (less than 2.5 m, 8.5 ft) may use the Eastern Passage, which runs on the east side of McNabs Island; however, continuous silting makes charted depths unreliable.

Large vessels have compulsory pilotage, with harbour pilots boarding at the pilot station off Chebucto Head. Vessels wishing to transit The Narrows between the outer harbour and Bedford Basin must travel one at a time; this rule was established after the disastrous Halifax Explosion of December 6, 1917 when a collision between the French munitions ship Mont-Blanc and the Norwegian Imo destroyed part of Halifax and Dartmouth.

The Royal Canadian Navy (RCN) maintains a large base housing its Atlantic fleet, Maritime Forces Atlantic (MARLANT), along the western side of The Narrows, as well as an ammunition depot (CFAD Bedford) on the northeastern shore of Bedford Basin. There are strict security regulations relating to vessels navigating near RCN facilities and anchorages.

There are two large suspension bridges crossing The Narrows:

• the Angus L. Macdonald Bridge, opening in 1955
• the A. Murray MacKay Bridge, opening in 1970
