Trinity—Spadina

Trinity—Spadina occupied the western portion of downtown Toronto, stretching from Lake Ontario north to the CP Rail line near Dupont Street. Its eastern boundary ran along Avenue Road, Queen's Park Crescent, and Yonge Street, while its western edge followed a jagged line along Ossington Avenue, Dovercourt Road, and Dufferin Street before wrapping around the Canadian National Exhibition grounds to the lakeshore. The riding contained some of the most iconic neighbourhoods in the city, including Chinatown, Kensington Market, Little Italy, Little Portugal, the Annex, and the emerging CityPlace condo district along the waterfront.

Candidates

Olivia Chow (NDP) — Chow had represented Trinity—Spadina since winning the seat from Liberal incumbent Tony Ianno in the 2006 federal election. Born in Hong Kong, she immigrated to Canada with her family in 1970 at the age of thirteen and attended Jarvis Collegiate Institute. Chow began her political career as a Toronto school board trustee, elected in 1985, a position she held for six years. She then served on Metropolitan Toronto Council starting in 1991 and continued on Toronto City Council after amalgamation until 2005. In Parliament, she focused on immigration, transit, and child nutrition. She was married to NDP leader Jack Layton, making them the second husband-and-wife team to serve simultaneously in the House of Commons.

Christine Innes (Liberal) — Innes was a political organizer and the wife of Tony Ianno, who had served as the Liberal MP for Trinity—Spadina from 1993 to 2006. She had worked as a political aide to Ontario Tourism Minister Michael Chan. Innes had run against Chow in the 2008 election as the Liberal candidate for Trinity—Spadina and was seeking a second attempt at the seat in 2011.

Gin Siow (Conservative) — Siow immigrated to Canada from Malaysia in 1982 and was co-owner of Markham Mazda. He was the founder of the Malaysia Association of Canada and received the Outstanding Asian Canadian Community Award from the Canadian Multicultural Council in 2009.

About the Riding

Trinity—Spadina was one of the most densely populated and diverse ridings in Canada, with a population of approximately 130,000. The riding was a microcosm of Toronto's multiculturalism, home to long-established Chinese, Portuguese, Italian, and Korean communities alongside newer immigrant populations. Kensington Market, a hub of independent shops and street vendors, was a defining feature of the riding's character.

The riding's economy was driven by the downtown service sector, with major employers including the University of Toronto's St. George campus, the CBC's Canadian Broadcasting Centre, and the cluster of financial and media firms along the southern waterfront. The Rogers Centre, Air Canada Centre, and Metro Toronto Convention Centre anchored a significant entertainment and tourism economy. The CN Tower, one of Canada's most recognizable landmarks, stood within the riding's boundaries.

A defining feature of the riding heading into 2011 was the rapid pace of condominium development along the waterfront and the King–Spadina corridor. The CityPlace development alone was adding tens of thousands of new residents, raising questions about infrastructure capacity, transit access, and community services. Many of these new residents were young professionals and renters, altering the riding's traditional demographic balance. Transit, including the future of streetcar service and waterfront access, was a key local concern. The riding also grappled with homelessness and affordable housing pressures, particularly around the Spadina Avenue corridor and Queen Street West.
