The Halifax area contains over 70 documented wreck sites spanning centuries. Among the most popular are HMCS Saguenay, a World War Two destroyer lying in 27 metres near Herring Cove, and the SS Havana, a steel-hulled steamer broken up on a reef near Sambro. The approaches to Halifax were heavily used during both World Wars as a convoy assembly point, resulting in numerous losses from U-boat attacks and maritime accidents. Colonial-era wooden sailing vessels, though less intact, can be explored at several sites within the harbour. Many wrecks are actively researched by local maritime archaeological groups.

Halifax's North Atlantic waters require serious exposure protection. Water temperatures range from near freezing at 2 degrees Celsius in winter to a maximum of about 18 degrees in late summer. Dry suits are standard for all Halifax diving, even during the warmest months, as bottom temperatures at wreck depths can be significantly colder than the surface due to thermoclines. Thick gloves, hoods, and warm undergarments are essential. Most local dive operators provide dry suit orientation for visiting divers not accustomed to cold-water equipment.

While some shallower wreck sites and shore dives near Halifax are suitable for certified beginners with cold-water experience, most of the significant wreck dives are recommended for intermediate to advanced divers. The combination of cold water, variable visibility, currents in the harbour approaches, and the depth of many wrecks creates conditions that benefit from experience. Several Halifax dive shops offer guided wreck dive packages that include thorough briefings and experienced divemasters. Beginners are typically directed to calmer, shallower sites before progressing to the deeper wrecks.
