The political boundaries of York South—Weston may be redrawn. The easternmost boundary would be moved from the train tracks near Caledonia Road to Keele Street. The move would occur as a result of population shifts and growth in Toronto, and the lines would be redrawn by an independent commission. The villages of Weston and Mount Dennis would not be affected by the change.
Both the provincial and federal ridings would change; they, by law, are identical.
