While at 110,000, East York has an ideal riding size, so do its constituent ridings. East York in of itself is less of a community of interest than it used to be, due to amalgamation. Don Valley West has slightly more people than average, so it might be an idea to move the neighbourhood of Thorncliffe Park into Toronto--Danforth, as it has similar demographics. That neighbourhood is separated from the rest of Don Valley West by industrial areas and railroads while it is separated from Toronto--Danforth by the Don River.
Until 1999, East York was divided into two ridings: Don Mills and York East. York East made up the bulk of the borough, whereas Don Mills included the area north east of Taylor Creek. For the purposes of our analysis, we will look at York East, which has been in existence since 1867:
1) H.P. Crosby (1867-1874)
2) Jno. Lane (1874-1879)
3) G.W. Badgerow (1879-1886)
4) G.B. Smith (1886-1894)
5) Jno. Richardson (1894-1904)
6) Alex. McCowan (1904-1913)
7) G.S. Henry (1913-1943)
8) A.C. Macphail (1943-1945)
9) J.A. Leslie (1945-1948)
10) A.C. Macphail (1948-1951)
11) H.E. Beckett (1951-1967)
12) A.K. Meen (1967-1977)
13) R.G. Elgie (1977-1985)
14) Christine Hart (1985-1990)
15) Gary Malkowski (1990-1995)

Political geography (2008 election)
The Liberals won Don Valley West and Beaches-East York, so those were their best areas. Specifically, The Liberals had their best showing in parts of Woodbine Gardens, Crescent Town and Topham Park . The NDP did their best in the Pape Village area, which is part of Toronto--Danforth, a riding they won. However, they also won many polls in Woodbine Gardens, and even one in Don Valley West, specifically in Thorncliffe Park. The Tories had their best showing in Leaside, winning just two polls outside of that area.
