Tommy Thompson Park Toronto s Urban Wilderness
Park History Early Construction Construction began in 1959 by Toronto Harbour Commissioners Expand port related facilities Dispose of rubble and fill from the construction industry Create opportunities for dredged material disposal
Park History In the 1970s Expected increase in shipping not realized Vegetation communities naturally established on constructed lands Wildlife and public benefiting from the lands TRCA awarded the responsibility of interim management and Master Plan development 1978 2002
Master Plan (1989) and Addendum (1992) The main objectives of the Master Plan are to: Preserve significant species Protect environmentally significant areas Enhance aquatic and terrestrial habitat Enhance public recreational opportunities
Ecological Significance The ecological health of the shoreline and adjacent watersheds are closely connected and dependant on Tommy Thompson Park Don River Watershed Portlands Toronto Islands Tommy Thompson Park

Recaptures The Story of 2210-5811 - Yellow Warbler Adult male originally banded on May 20, 2003, has been recaptured at TTPBRS 21 times! He has migrated back and forth between Toronto and Latin America at least ten times covering 30,000 kilometres! He establishes a territory at TTP in almost exactly the same place year after year.
Winged Migration Education Program I loved watching the birds and learned the great things about nature. I took some pictures and I will never forget the memory of the beautiful birds. ~ Grade 6 student
