This downtown Toronto riding mixes the wealthy enclave of Rosedale with the densely populated apartments of St. Jamestown and a noted gay district.

The riding stretches north from Toronto Harbour to the southern boundary of Mount Pleasant Cemetery, between the Don River in the east and Avenue Road, Queen's Park, College Street and Yonge Street in the west.

The riding of Rosedale was established in 1933. Its name was changed to Toronto Centre-Rosedale in 1996 and to Toronto Centre in 2004, when it added a small part of St. Paul's in the northwest and Toronto-Danforth in the northeast.

Population: 121,407 (2006 census; an increase of six per cent since 2001)

In the 2008 election, Liberal Bob Rae easily held the riding he had won in a byelection to replace MP Bill Graham earlier in the year. Rae garnered almost three times the number of votes of second place candidate Conservative David Gentili. In 2006, Liberal incumbent Bill Graham beat New Democrat Michael Shapcott and received twice the number of votes to win his fifth term. Graham also defeated Shapcott in the 2004 election.

In February 2006, Graham was appointed interim leader of the Liberals and became Opposition leader. Graham was minister of foreign affairs from 2002 to 2004, when then prime minister Paul Martin made him minister of national defence.

In 1988, PC David MacDonald, who had served four terms in Egmont riding in Prince Edward Island, defeated Graham by 80 votes. In 1993, Graham defeated MacDonald. In 1997, MacDonald transferred to the New Democrats and was defeated in Toronto Centre-Rosedale.

Liberal Donald Macdonald, who was government House leader; minister of defence; minister of energy, mines and resources; and minister of finance in the Trudeau era, was MP for Rosedale from 1962 to 1978, when he resigned.

In a byelection to replace him in October 1978, Conservative David Crombie was elected. Crombie was re-elected in 1979, 1980 and 1984, and was minister of health and welfare, minister of Indian affairs and northern development and minister responsible for multiculturalism in the Mulroney era. He resigned in 1988.
