Toronto Centre () is a federal electoral district in Toronto, Ontario, Canada, that has been represented in the House of Commons of Canada from 1872 to 1925, and since 1935, under the names Centre Toronto (1872–1903), Toronto Centre (1903–1925, and since 2004), Rosedale (1935–1997), and Toronto Centre—Rosedale (1997–2004). Toronto Centre contains a large part of Downtown Toronto. The riding contains areas such as Regent Park (Canada's first social housing development), St. James Town (a largely immigrant area and the most densely populated neighbourhood in Canada), Cabbagetown, Church and Wellesley (a historic LGBTQ2 neighbourhood), Toronto Metropolitan University, the Toronto Eaton Centre and part of the city's financial district (the east side of Bay Street). At just under , it is the smallest riding in Canada by area. History Centre Toronto riding was first created in 1872 from portions of West Toronto and East Toronto. In 1903, the name was changed to Toronto Centre. In 1924, the riding was broken into Toronto East Centre, Toronto West Centre and Toronto South. A riding covering much the same area was created in 1933 named "Rosedale" after the wealthy neighbourhood of Rosedale. This riding was replaced with "Toronto Centre—Rosedale" in 1996, but the quickly growing population resulted in large areas being shaved off on all sides. In 2003, Toronto Centre—Rosedale was abolished, and a new riding somewhat to the east was created named "Toronto Centre". Each of the four major national political parties (the Liberal Party, the Conservative Party, the Green Party, and the NDP), have active federal and provincial riding associations which act as the local party organizations in the riding. Since the early 1990s, however, most contests have been between the Liberals and NDP. This riding lost territory to University—Rosedale and Spadina—Fort York, and gained a small fraction of territory from Trinity—Spadina during the 2012 electoral redistribution. This made Toronto Centre the smallest size riding in the country, beating Papineau in Montreal by 4 km2. Historically, the riding was one of the few in central Toronto where the Progressive Conservatives usually did well. The PCs held the riding for 34 of the 58 years from 1935 to 1993. However, it has been in Liberal hands without interruption since 1993. The 2012 federal electoral redistribution shifted much of the wealthier northern part of the riding, which included Rosedale, to the new riding of University—Rosedale. The riding was represented by former interim Liberal leader Bob
