Diving in Canada
Including Fathom Five National Marine Park (Tobermory), God's Pocket Marine Park (Port Hardy), and Halifax Coastal Wrecks. On the map.
The vibe
Diving in these waters is a serious, technical pursuit focused on historic shipwrecks and vibrant, cold-water marine life that thrives in the depths. You need to plan your dives for the warmer months to avoid the harshest conditions, and the scene is dominated by dedicated local clubs rather than casual holiday operators. Expect a professional, gear-heavy atmosphere where safety and thermal protection are the primary concerns.
