[1] It is a tributary of Lake Ontario and runs from Caledon to southern Etobicoke, part of the City of Toronto.

[8]: 97 : 99  "Creek" was officially adopted by the Geographical Names Board of Canada on November 18, 1962,[1] though it existed far earlier.

[9] The name of the river in Anishinaabemowin (Ojibwe) language of the Mississaugas, in modern Fiero orthography is Edoopikaag-ziibi.

[10] Etobicoke Creek begins south of the Oak Ridges Moraine and flows through Caledon, Brampton, and Mississauga — west of the Toronto Pearson International Airport and the surrounding industrial area — to its mouth at Lake Ontario in the Etobicoke portion of the city of Toronto.

[11] The creek's southern section forms a city and county-level boundary, separating Toronto on the east from Mississauga, in Peel Region, as far north as Eglinton Avenue (north of where it flows entirely through Peel), on the west.

The position of the ravine so close to the airport's overrun area has raised some concerns among the general public,[16] despite Toronto Pearson's compliance with all safety regulations.
