“Toby” is likely the best known dive destination in all of Ontario among non-divers. It was the site of Canada’s first underwater national marine park, and continues to attract hordes of divers each season to it’s cold water and good visibility. Those hordes have been steadily declining in numbers as other Ontario locations become better known (and zebra mussels continue to clear up the visibility making Lakes Erie and Ontario more diver friendly). Tobermory has never heard of warm water, at least not when it comes to diving. Even on the warmest summer day leaving your hood on the boat is not advised if you are going below 20’. Wrecks range in depth from 10’ to 150’ so there’s something for everyone. The most intact wrecks are the schooner Arabia and sand-sucker barge Niagara II which was intentionally sunk as a dive site.
