Oak Hall is a 37-room, three-story Tudor-style stone mansion that was built in the late 1920s for mining tycoon Harry Oakes (1874–1943). It is located in Niagara Falls, Ontario, approximately 1/4 mile southwest of the Canadian Horseshoe Falls. In 1959, Oak Hall was bought by the Niagara Parks Commission and opened to the public in 1964. The estate's original 9-hole golf course was turned into a public course in 1966. The mansion has housed the offices of the Niagara Parks Commission since 1982, and several historic rooms are still open for public viewing.

Marineland (official name Marineland of Canada Inc.), is a themed zoo and amusement park in Niagara Falls, Ontario, Canada. The park has performing marine animal shows, exhibits of marine and land animals, and amusement rides. It keeps dolphins, sea lions, and beluga whales. Until 2023, the park also kept walruses and orcas. The park also keeps bears, deer, and other land animals. It was founded and operated by John Holer, a Slovenian immigrant, from 1961 until his death in 2018. It is privately owned and operated by his family. The park's keeping of marine mammals is controversial, and the park is involved in several lawsuits related to the practice. The keeping of the sea mammals is opposed by animal rights activists, and Marineland has been the site of numerous animal rights demonstrations.

The Niagara Scow (also called the Old Scow or Iron Scow) is the unofficial name of the wreck of a small scow that brought two men perilously close to plunging over the Horseshoe Falls, the largest of the Niagara Falls, in 1918. The wreck can still be seen, upstream of the falls.

The Toronto Power Generating Station is a former generating station located along the Niagara River in Niagara Falls, Ontario, Canada, slightly upstream from the newer Rankine power station. Completed in 1906 in the Beaux-Arts-style, the station was designed by architect E. J. Lennox and was built by the Electrical Development Company of Ontario (owned by William Mackenzie, Frederic Thomas Nicholls, and Henry Mill Pellatt) under supervision of Hugh L. Cooper to supply hydro-electric power to nearby Toronto, Ontario.The plant is built on top of a deep wheel pit, with turbines at the bottom of the pit, turning generators at the top by means of long vertical shafts. The water from the turbines runs out through a brick-lined tailrace which eventually comes out at the base of the falls. In its prime, it had a generating capacity of 137,500 horsepower (102,500 kW).The plant ceased operations on February 15, 1974 as Ontario Hydro looked to make better use of the available water downriver at the Sir Adam Beck Hydroelectric Power Stations in Queenston. In addition, the plant produced "25 Cycle" electricity, now largely unused. The vacant plant was designated a National Historic Site of Canada in 1983, due to its importance in the development of business, industry and technology in Ontario, its status as the first wholly Canadian-owned hydro-electric facility at Niagara Falls, and the unusual application of Beaux-Arts design to an industrial plant.Ownership of the Toronto Power Generating Station was transferred to the Niagara Parks Commission in 2007. Structural assessments were subsequently undertaken in order to consider future adaptive reuse options for the facility. In its current empty state, the plant has been the subject of urban exploration activities.

The Rankine Generating Station is a former hydro-electric generating station along the Canadian side of the Niagara River in Niagara Falls, Ontario, slightly downstream from the older Toronto Power Generating Station. It was built in for the Canadian Niagara Power Company and named for company's founder William Birch Rankine (b. 1858), a New York City (and later of Niagara Falls) lawyer originally from Geneva, New York who died three days after (in Grafton, New Hampshire) the station opened in 1905 and renamed in 1927. Acquired by Niagara Mohawk Power Corporation in 1950 and in 2002, the station became a wholly owned subsidiary of FortisOntario (and part of Canadian owned Fortis Inc.). It was decommissioned in 2006. It reopened in July 2021 as a tourist site.

Horseshoe Falls is the largest of the three waterfalls that collectively form Niagara Falls on the Niagara River along the Canada–United States border. Approximately 90% of the Niagara River, after diversions for hydropower generation, flows over Horseshoe Falls. The remaining 10% flows over American Falls and Bridal Veil Falls. It is located between Terrapin Point on Goat Island in the US state of New York, and Table Rock in the Canadian province of Ontario. These falls are also referred to as the Canadian Falls.

Brother Island is a small, uninhabited island off the coast of Goat Island in the U.S. state of New York. It lies in the Niagara River, close to the Horseshoe Falls and the Three Sisters Islands. It is part of the city of Niagara Falls. It is one of only five islands in the area surrounding the Horseshoe Falls which have not been claimed by Canada.

The Three Sisters Islands are islands which lie off the south shoreline of Goat Island. The islands are part of Niagara Falls, New York. Accessible from Goat Island, the Three Sisters Islands are located just beyond the Canada/U.S. border in Niagara Falls, New York. The islands are named after Celinda, Angelina, and Asenath Whitney (all three of whom are buried in Oakwood Cemetery in Niagara Falls, NY), daughters of General Parkhurst Whitney of Niagara Falls, New York. General Whitney (also buried in Oakwood Cemetery), was a prominent early settler of Niagara Falls, New York. The General moved to Niagara Falls, N.Y. in 1810 and is best known as the founder and operator of the Cataract House Hotel located near the upper rapids just above the falls. General Whitney's daughters are believed to be the first settlers to have trekked to the three small islands. Before European settlers arrived in North America, Iroquois shamans made sacrifices of food and gifts on the islands and communed with He-No (Mighty Thunderer), the spirit who dwells in the mist-enshrouded cave at the base of the falls. Modern day psychics believe any one can hear the voices of the spirits if they listen carefully while visiting the Three Sisters Islands. Each island supports a variety of microhabitats and has its own floristic character. The Three Sisters Islands are connected by bridges, allowing pedestrians to walk to all three for grand views of the raging rapids in the Niagara River right before its descent over the Horseshoe Falls.

Cedar Island was a small, uninhabited and elongated island located in the Niagara River near the Canadian shore, opposite the Table Rock observation area at the brink of the Horseshoe Falls.

The Niagara River () is a river that flows north from Lake Erie to Lake Ontario. It forms part of the border between the province of Ontario in Canada (on the west) and the state of New York in the United States (on the east). There are differing theories as to the origin of the river's name. According to Iroquoian scholar Bruce Trigger, Niagara is derived from the name given to a branch of the locally residing native Neutral Confederacy, who are described as being called the Niagagarega people on several late-17th-century French maps of the area. According to George R. Stewart, it comes from the name of an Iroquois town called Ongniaahra, meaning "point of land cut in two".The river, which is occasionally described as a strait, is about 58 kilometres (36 mi) long and includes Niagara Falls in its course. The falls have moved approximately 11 kilometres (6.8 mi) upstream from the Niagara Escarpment in the last 12,000 years, resulting in a gorge below the falls. Today, the diversion of the river for electrical generation has significantly reduced the rate of erosion. The total drop in elevation along the river is 99 metres (325 ft). The Niagara Gorge extends downstream from the Falls and includes the Niagara Whirlpool and another section of rapids. Power plants on the river include the Sir Adam Beck Hydroelectric Power Stations (built in 1922 and 1954) on the Canadian side, and the Robert Moses Niagara Power Plant (built in 1961) on the American side. Together, they generate 4.4 gigawatts of electricity. The International Control Works, built in 1954, regulates the river flow. Ships on the Great Lakes use the Welland Canal, part of the Saint Lawrence Seaway, on the Canadian side of the river, to bypass Niagara Falls. The Niagara River also features two large islands and numerous smaller islands. Grand Island and Navy Island, the two largest islands, are on the American and Canadian sides of the river, respectively. Goat Island and the tiny Luna Island split Niagara Falls into its three sections, the Horseshoe Falls, Bridal Veil Falls, and American Falls. Unity Island lies further upstream, alongside the city of Buffalo. The Niagara River and its tributaries, Tonawanda Creek and the Welland River, formed part of the last section of the Erie Canal and Welland Canal. After leaving Lockport, New York, the Erie Canal proceeds southwest until it enters Tonawanda Creek. After entering the Niagara River, watercraft then proceed southward to the final lock, where a short section of the canal allows boats to avoid the turbulent shoal water at the river intake and enter Lake Erie. The Welland Canals used the Welland River as a connection to the Niagara River south of the falls, allowing water traffic to safely re-enter the Niagara River and proceed to Lake Erie.

The Niagara Tunnel Project was part of a series of major additions to the Sir Adam Beck hydroelectric generation complex in Niagara Falls, Ontario, Canada. Water delivered by the major new tunnel complements other upgrades to the Sir Adam Beck Hydroelectric Generating Stations, resulting in more efficient use of the Niagara River's hydro power. The project's new 12.7 metres (42 ft) diameter, 10.2 kilometres (6.3 mi) long tunnel was officially placed into service on 21 March 2013, helping to increase the generating complex's nameplate capacity by 150 megawatts, with the extra power produced enough for approximately 160,000 homes.

Niagara Falls State Park is located in the City of Niagara Falls in Niagara County, New York, United States. The park, recognized as the oldest state park in the United States, contains the American Falls, the Bridal Veil Falls, and a portion of the Horseshoe Falls (also known as the Canadian Falls).
