Grand River Naval Depot

Grand River Naval Depot was a planned base on Lake Erie in what is now Port Maitland, Ontario, Canada.

Located at the mouth of the Grand River, the naval base was to have been built as a second naval base on Lake Erie intended to complement the base at Navy Island. It was to have stationed 1,000 sailors and 3 frigates and was to have been a key player in the War of 1812 and the Rush-Bagot Treaty of 1817. It was never completed and the site was abandoned by the Royal Navy. It is now the site of Esplanade Park in Port Maitland.
