And if you’ve never donned a tank and fins, there are several operators in Ontario for beginning scuba divers to learn the skills and regulations you need.

Whether you’re a beginner or an avid diver, you’ll love the unique scuba diving experiences in Ontario.

Learn to scuba dive

Before you hit the open waters, you need to learn how to dive with a certified scuba instructor and get the proper designation.

The Professional Association of Diving Instructors (PADI) is a globally recognized diver training organization with thorough courses that cover the basics, like getting into the water safely, how to clear your mask, start breathing and get underwater in the safety of a pool.

Located in St. Catharine’s, Dan’s Dive Shop is the oldest PADI dive school in Canada and offers everything from beginner’s courses to refreshers for certified divers. Divers-in-training will love the scuba classes at Scuba 2000, a state-of-the-art dive shop and instruction centre in Richmond Hill. Besides certified lessons and gear, they also offer unique diving events and trips. 

Where to scuba dive in Ontario

Popular dive sites include the ‘Graveyards of Lake Ontario’, Lake Ontario's 'Bermuda Triangle' in and around the Prince Edward Bay, the wrecks of Lake Erie, the 22 historic shipwrecks protected in Fathom Five National Marine Park, off of Tobermory, in the Georgian Bay and the Kingston shipwrecks in the St. Lawrence River. The 1879 Waubuno Shipwreck is one of the most famous freight wrecks to dive to in the Parry Sound area, on the southern tip of Bradden Island.
