Toronto’s Don River was declared “biologically dead” decades ago — now fish are returning after a major wetland restoration. Monitoring in 2025 recorded more than 20 fish species in Toronto’s Don River, including Atlantic salmon and native predators such as walleye and northern pike. The rebound follows a C$1 billion renaturalisation that rebuilt wetlands, reshaped the river’s course, and restored spawning habitat.
