Formerly called | Mississauga Garden Council |
The Riverwood Conservancy (TRC) is a volunteer- and member-based registered charity that operates programs in environmental education, conservation, and horticulture at Riverwood, a 150 acres (61 ha) public park on the Credit River in Mississauga, Ontario, Canada. The organization was founded in 1985 as the Mississauga Garden Council.[1][2] The park, co-owned by the City of Mississauga and Credit Valley Conservation, contains heritage structures, gardens, and ecosystems that the City of Mississauga has described as among the most diverse in the Credit River watershed.[3]
History
Pre-colonial and early settlement
The land occupied by Riverwood was originally the territory of Indigenous peoples within the Credit River valley. In 1833, the Crown land was granted to Peter McDougall, and the property changed hands among several owners over the following decades.[4] A barn constructed around 1865, now known as the MacEwan Barn, survives from this agricultural period. Built of heavy hewn timber and clad in vertical boards, the structure retains its original form.[4]
The Parker estate (1913 to 1954)
In 1913, Toronto lawyer and mining executive W. R. Percy Parker and his wife Ida Margaret Kerr purchased the property as a summer retreat.[5] Ida Parker named the estate "Riverwood" after the Credit River and surrounding woodlands. The Parkers first rebuilt an earlier stone cottage on the site (now the MacEwan House), spending six summers there before commissioning a larger residence.[5]
In 1919, Parker hired the Toronto architectural firm Mathers and Haldenby to design a main house in the Arts and Crafts style. The house was constructed from Credit Valley stone gathered on the property and featured a U-shaped floor plan, a steeply pitched cross-hip roof with wood shingles, and an external chimney with a hand-carved stone shield.[4] Landscape architects William Harries, Alfred Hall, and Arthur Kruse designed the grounds, which moved from formal gardens near the house to naturalistic plantings further afield.[4]
The Parkers entertained prominent figures at the estate. According to Heritage Mississauga, Prime Minister William Lyon Mackenzie King visited the property on at least three occasions, in 1921, 1925, and 1929, and a bedroom was reportedly reserved for his use.[5] The property was featured in Canadian Homes and Gardens magazine in May 1929.[5]
After Percy Parker's death, Ida Parker sold the property in stages due to financial difficulties. In the late 1930s, her daughter Margaret MacEwan purchased the parcel containing the stone cottage. In the 1940s, John and Theodosia Zaichuk acquired the upper farm portion. In 1954, Hyliard Chappell, a Queen's Counsel who later served as Member of Parliament for Peel South (1968 to 1972), and his wife Grace purchased the main house and surrounding land.[4][1]
Municipal acquisition and park creation (1985 to 2005)
In September 1985, the Mississauga News reported that the City of Mississauga sought to acquire riverside land for a public garden.[6] The City purchased the Chappell property in 1986 and the Zaichuk property in 1989, reassembling the estate into a single 150 acres (61 ha) parcel.[6][1]
Plans for the site generated public debate. The Toronto Star reported in January 1992 that opponents criticized a $39.5-million public garden proposal, and in March 1992 the newspaper reported that Mississauga council voted to override the critics.[6] An environmental assessment was conducted, and the Mississauga News reported in November 1994 that the garden project had been "dealt a stinging blow."[6] According to The Globe and Mail, after a six-year environmental study the city "lost an appetite for the project and money was scarce," and plans stalled until the mid-1990s.[1]
Momentum revived when the Mississauga Board of Trade relocated its offices to the Parker/Chappell residence in 2001.[1] In 2002, the City retained the landscape architecture and urban design firm du Toit Allsopp Hillier to develop a master plan for the site, including restoration of the MacEwan House and barn, new road infrastructure, and an inventory of architectural remnants on the property.[1]
On December 15, 2004, the City of Mississauga designated Riverwood as a property of heritage significance under By-law 505-2004, pursuant to Part IV of the Ontario Heritage Act. The property was subsequently listed on the Canadian Register of Historic Places on October 21, 2009.[4]
In September 2005, The Globe and Mail architecture columnist Dave LeBlanc described the site as a potential peer to Toronto's High Park, reporting that landscape architect John Hillier of du Toit Allsopp Hillier called working on Riverwood a rare opportunity. The same year, a new building designed by architect Brian Brownlie opened as the home of Visual Arts Mississauga.[1]
Post-2005 development
The MacEwan Terrace Garden, a two-acre accessible perennial garden, opened in 2012.[3] In 2016, the conservancy joined the Brueckner Hybrids Test Project, a cross-border study evaluating more than 100 Rhododendron hybrids developed by the late Dr. Joseph Brueckner of Mississauga to test cold-hardy cultivars.[7]
In 2020, the Mississauga News reported that the conservancy received a $213,800 grant from the Ontario Trillium Foundation to fund a three-year expansion of volunteer conservation, wildlife tracking, and citizen science programs.[2]
Site and ecology
Riverwood spans 150 acres (61 ha) along the east bank of the Credit River and includes meadows, old-growth forest, ravines, wetlands, and creeks.[3] The City of Mississauga states that over 160 bird species have been identified at the site, and the conservancy reports more than 200 species observed, along with populations of white-tailed deer, mink, beavers, and opossums.[3]
The park is divided into four interpretive terraces named for former property owners: Bird Terrace, MacEwan Terrace, Zaichuk Terrace, and Chappell Terrace. Each terrace reflects a different period of the property's agricultural and residential history.[4]
Heritage structures
The site contains several structures recognized in the heritage designation:
- Chappell House (1919): Designed by A. S. Mathers in the Arts and Crafts style, constructed of Credit Valley stone. Currently serves as the Riverwood Conservancy's headquarters.[4][3]
- MacEwan House (c. 1914): A single-storey vernacular stone cottage built on the ruins of an earlier structure using local shale. Enlarged in the 1950s.[4]
- MacEwan Barn (c. 1865): A one-and-a-half-storey barn of heavy hewn timber with vertical board cladding, retaining its original 1850s hand-hewn beams.[4][3]
- Visual Arts Mississauga Building (2005): Designed by architect Brian Brownlie to complement the heritage structures in material and style.[1]
Gardens
The conservancy maintains several public gardens on the property:[7]
- Chappell House Garden: Designed in the Arts and Crafts style around the original circular driveway and lily pond.
- Rhododendron Garden: Contains cultivars from the Brueckner Hybrids Test Project.
- MacEwan Terrace Garden: A two-acre accessible perennial garden opened in 2012.
- Vegetable Garden: Produces food donated to the Compass Food Bank in Port Credit.
Limitations and criticism
The original public garden proposal faced sustained opposition in the early 1990s. The Toronto Star reported in January 1992 that critics objected to the estimated $39.5-million cost, and the paper described opponents calling for a scaled-down effort.[6] The Mississauga News reported in 1994 that the project was dealt a setback, and the Globe and Mail noted that the city lost interest in the project for several years due to funding constraints.[1][6]
As of 2005, The Globe and Mail reported that Riverwood remained "little known outside of Mississauga's borders and, perhaps, even by city residents themselves," despite its size and central location.[1]
Conservation challenges
The conservancy has identified habitat degradation from surrounding urban development, invasive plant species, and the effects of increased public use as ongoing ecological pressures on the site.[8] The City of Mississauga has published an invasive species management plan that encompasses properties within the Credit River corridor, including Riverwood.[9]
Governance and funding
The Riverwood Conservancy operates as a registered charity governed by a volunteer board of directors. Funding comes from membership fees, donations, program fees, and government grants. The Ontario Trillium Foundation has awarded multiple grants to the organization, including $213,800 in 2020 for conservation programming and $20,300 in 2026 for program space upgrades.[2]
The 150 acres (61 ha) park itself is co-owned by the City of Mississauga and Credit Valley Conservation, with the conservancy serving as the programming and stewardship partner.[3]
Other organizations at Riverwood
Visual Arts Mississauga, a non-profit organization offering art classes and exhibitions, has been based at Riverwood since 2005.[1][3]
