Presqu'ile Provincial Park is a park in southeastern Northumberland County on the north shore of Lake Ontario near the town of Brighton in Ontario, Canada. The park occupies an area of 9.37 km2 (3.62 sq mi). The name of the park is the French word for peninsula, or literally "almost island", and was believed to be named by Samuel De Champlain on his second expedition. The peninsula was formed when a limestone island was connected to the mainland by a sand spit; this kind of formation is referred to as a tombolo.
The Slate Islands are a small archipelago in Lake Superior, Ontario, Canada, about 12 kilometres (7.5 mi) south of the town of Terrace Bay. The island group, consisting of 15 islands in total, was created by a meteorite impact which formed a crater about 32 km (20 mi) wide. In 1985, the Ontario government established the Slate Islands as a natural environment provincial park. The islands are notable for having Ontario's largest herd of boreal woodland caribou.
Middle Island is a small island, just 18.5 hectares in area. It is the southernmost point of land in Canada, located at 41°41'N, 82°41"W (41.685,-82.684), or about 41.7 degrees north latitude. It lies in Lake Erie, just south of Pelee Island, and is part of Point Pelee National Park. It forms part of the province of Ontario.

Mohawk Island is a small island in the northeast of Lake Erie, in Haldimand County, Ontario, Canada. It is composed of limestone with almost no vegetation, and is close to the water level. It was formerly known as Gull Island and contains the ruins of the Gull Island Lighthouse which was built in 1848 to guide ships into the Welland Canal at Port Maitland. In 1933, the lighthouse was automated to no longer require a human keeper and lost significance in 1934 due to the realignment of the canal at Port Colborne. It was decommissioned in 1969 when the mechanism was destroyed by a fire. The lighthouse is located close to the shore of Rock Point Provincial Park.
Carleton Island is located in the St Lawrence River in upstate New York. It is part of the Town of Cape Vincent, in Jefferson County.
The Cove Island Light, at Gig Point on the island, is located in Fathom Five National Marine Park, but is not part of the Park. It is situated on the Bruce Peninsula, Ontario, Canada. It has been a navigational aid in the narrow channel between Lake Huron and Georgian Bay since 30 October 1858. It was the first of six stone Imperial Towers to be completed; all were illuminated by 1859. Most other lighthouses of the era were built of brick, wood, iron or concrete.
Trillium Power Wind 1 (TPW1) is a proposed 450 to 500 megawatt (MW) far-offshore wind farm in the Canadian waters of northeastern Lake Ontario at least 17 to 28 km from the nearest mainland. This renewable energy project is being developed by Trillium Power Wind Corporation, a privately-held, Canadian-owned company headquartered in Toronto, Ontario. The project was placed in moratorium by the Ontario government on February 11, 2011 at exactly the same hour that Trillium Power was completing a $26 Million financing. A larger follow on equity investment of $400 Million was in discussion with two large global pension funds at the time. Had it not been placed in abeyance, TPW1 would have been the first offshore wind farm built in the Great Lakes. Recently, on January 19, 2023, the Ontario Court of Appeal heard an appeal by Trillium Power, focusing on evidence provided by Trillium Power of spoliation in an ongoing litigation by the Ontario Government.
