Coordinates: 43°04′07″N 79°04′14″W / 43.068613°N 79.070685°W Dufferin Islands are a group of scenic man-made islands located in Niagara Falls, Ontario, approximately 1/2 mile south of the Horseshoe Falls. The islands are known for their quiet seclusion and nature trails.
While Niagara Falls, New York became more well known for industry development along the lower river's edge in the 1870s, the industrial revolution started much earlier on the Canadian side. In 1794, permission was granted to erect a saw and grist mill at the eastern end of the islands. This was followed by an iron ore mill constructed in 1796. Ownership of the properties was transferred to area pioneers Samuel Street and Thomas Clark by 1801, with the islands named Clark Hill Islands in 1805. The mills were burned by American forces on July 26, 1814, following the Battle of Lundy's Lane during the War of 1812.
Thomas Clark "T.C." Street took ownership of Clark Hill Islands in 1854, renaming them Cynthia Islands. They became accessible to the public in 1877, when Sutherland Macklem, Street's heir, built a pair of suspension bridges to carry foot & carriage traffic across.
Pedestrian traffic had already been flocking to the surrounding grounds since the mid-1820s to visit The Burning Spring, billed as Niagara Falls' "first tourist attraction". It continued in operation for nearly sixty years, until the Niagara Parks Commission took over the property and Cynthia Islands as well, in 1887.
When the Parks Commission took over, they renamed the islands in honor of Canadian Governor-General Lord Dufferin, who had been instrumental in establishing parkland along the river to replace "The Front", a notoriously rowdy tourist area. The islands remained untouched until 1902, when the Ontario Power Company began construction on their lower river power facility, which required river water to be drawn from a point just east of the islands.
