Explore Ontario
Ontario offers a unique diving experience with its diverse aquatic landscapes, making it a remarkable destination for divers. In the north, the chilly waters of Hudson Bay, near the Arctic Circle, invite adventurous divers to explore a world unlike any other. While the temperatures rarely exceed 10°C/50°F, the vibrant marine life, including rare species, makes it worth braving the cold. A warm dry suit is essential here, but those who venture in are rewarded with encounters few divers get to experience.
In contrast, Ontario's southern border features four of the Great Lakes: Superior, Huron, Erie, and Ontario. These freshwater giants offer some of the world's best shipwreck diving. With spectacular visibility, particularly in winter and spring, divers can explore historical wrecks preserved in these cold, clear waters. The sheer number of wrecks promises endless exploration. Whether you prefer shore dives or boat trips, Ontario's dive sites cater to all styles, providing an unforgettable journey through Canada's rich underwater history.

Diving in Ontario
Ontario offers a diverse array of dive sites that cater to both wreck enthusiasts and those seeking serene underwater experiences. Notable wreck dives include the "Sweepstakes", a well-preserved schooner in Tobermory’s Fathom Five National Marine Park. This site is accessible for beginners and provides an intriguing glimpse into maritime history. Another fascinating wreck is the "Niagara II", also located in Tobermory, which offers a more challenging dive with its deeper depth and diverse marine life. Popular shore dives, such as those found at the Thousand Islands, allow divers to explore vibrant underwater ecosystems just a short swim from the shore. These sites are perfect for those who prefer the flexibility of shore diving over liveaboard trips. Unique experiences include night dives, where divers can witness the nocturnal behaviors of freshwater species, offering a different perspective of Ontario’s aquatic life. The balance between easily accessible shore dives and the adventure of liveaboard options makes Ontario a versatile destination for divers of all skill levels.
The best Months to dive in Ontario
Ontario offers diverse diving conditions throughout the year. In the warmer months, water temperatures range from 18°C–23°C/64°F–73°F, providing pleasant diving conditions with visibility typically between 15-30 meters/49-98 feet. During winter, temperatures can drop to 0°C–4°C/32°F–39°F, which restricts diving to those equipped for cold water conditions, as ice diving becomes prevalent.
Visibility can be affected by seasonal plankton blooms, especially in spring and early summer. Wind and surface currents are significant factors, particularly in larger bodies of water like the Great Lakes, potentially limiting diving opportunities. While diving is possible all year, the most favorable conditions are generally from late spring to early fall when water temperatures are comfortable, and visibility is at its best.
