Andrea Chreston of the Toronto and Region Conservation Authority (TRCA) observed trumpeter swans and their cygnets in Tommy Thompson Park, a five-kilometre urban wilderness park on Toronto’s waterfront.
Twenty years ago, the park was a barren landscape created from construction waste and dredged sediment deposited into Lake Ontario starting in 1959. The TRCA assumed responsibility for developing the area into a public park in 1973 and began habitat restoration projects in 1995.
The park now supports a diverse ecosystem including river otters, white-tailed deer, monarch butterflies, and over 300 bird species. It attracts roughly 300,000 visitors annually, primarily cyclists, walkers, and birdwatchers. The TRCA notes that Tommy Thompson Park is unique in Canada and possibly North America, as it is a man-made wilderness surrounded by water. The park’s success has drawn international interest, with officials from Korea visiting this spring to study its restoration methods.
In November 2025, the TRCA will receive an award in Geneva recognizing Tommy Thompson Park as a model for ecological restoration. The TRCA has also applied lessons learned to a new conservation area in Mississauga, and local groups like Friends of the Spit advocate for preserving the park’s natural state.
