Rouge National Urban Park, in the east end of Toronto and the neighbouring cities of Markham and Pickering, was established on May 15, 2015, when the Rouge National Urban Park Act came into force. Parks Canada gives the area as 79 square kilometres (about 30.5 square miles) once the park is complete, the Canadian Encyclopedia gives 79.1, and both call it Canada’s first national urban park. Parks Canada says human history in the valley goes back more than 10,000 years.
The Rouge Valley before the park
According to the Canadian Encyclopedia, people have been present in the Rouge area for more than 10,000 years. Parks Canada adds that the park holds some of the oldest known Indigenous sites in Canada. The Encyclopedia says farming began around 700 CE and Iroquoian villages followed, and that the Rouge River was part of a First Nations canoe route.
Bead Hill is the best documented of these sites. The Parks Canada register of national historic sites records it as a late-17th-century Seneca village and burial area dated to about 1665 to 1687, on 2.68 hectares, designated on November 22, 1991. The register calls it apparently the only known remaining intact 17th-century Seneca site in Canada, and notes an older Archaic campsite of about 3000 BCE. For the wider story of the First Nations of the Toronto region, see the article on Toronto’s Indigenous history and the account of the Toronto Purchase of 1787.
Europeans, mills, and farms
In 1669, Sulpician priests built a mission at the mouth of the Rouge, according to the Canadian Encyclopedia. A map attributed to Louis Jolliet is among the first by Europeans to show the Rouge and carries the word Taronto. The question of how that name reached the city is covered in the article on the origins of the name Toronto.
German Mennonite settlers arrived in the late 1700s, according to the Canadian Encyclopedia, and Parks Canada gives 1799 as the year settlers first arrived in the valley. The river powered mills: the Canadian Encyclopedia counts 54 on the Rouge by 1861. Parks Canada adds that later uses of the valley included orchards, a landfill, hotels, campgrounds, and cottages. The Canadian Encyclopedia notes that expropriation of farmland for an airport that was never built helped keep the area rural.
From citizen campaign to Rouge Park
The Canadian Encyclopedia dates the push to protect the valley to 1975, when the group Save the Rouge Valley System formed. A Rouge park was announced in 1990, a management plan followed in 1994, and the park opened in 1995. On June 15, 2019, the Toronto and Region Conservation Authority transferred 18.5 square kilometres to Parks Canada.
Creating a national urban park
The federal government committed in June 2011 to establish Canada’s first national urban park. In December 2014, Parks Canada signed a land assembly agreement with partners including the Toronto and Region Conservation Authority. The first lands, 19.1 square kilometres from Transport Canada, were transferred in April 2015, and the park was established on May 15, 2015.

What the Act says
The Rouge National Urban Park Act states the park’s purpose in section 4: to protect and present its natural and cultural heritage and diverse landscapes, to promote a vibrant farming community, and to encourage Canadians to connect with national protected heritage areas. Parks Canada says a 2017 amendment made ecological integrity the top management priority while giving park farmers long-term certainty. Section 6, as shown on the Justice Laws website, makes maintaining or restoring ecological integrity the first priority of the Minister, while allowing the agricultural activities the Act provides for. The Justice Laws page records that the Act received Royal Assent on April 23, 2015; amendments received Royal Assent in June 2017 according to the Parks Canada milestones page.
Nature in the park
The Canadian Encyclopedia lists close to 1,000 plant species, which is more than 25 percent of Ontario’s plant species, along with 247 bird, 73 fish, 44 mammal, and 27 reptile and amphibian species. All eight of Ontario’s bat species are found there. The same article states that roughly 75 percent of the park’s lands have been changed by farming or industrialization, which is why restoration is part of the work. Parks Canada began reintroducing Blanding’s turtles in June 2014, and its milestones page reported 165 juveniles released by 2019. For the geology of the nearby lakeshore, see the Scarborough Bluffs.
