Ottawa--Vanier--Gloucester

Ottawa--Vanier--Gloucester is a central Ottawa riding that has been a Liberal stronghold for nearly a century, with the party holding the seat continuously since 1935. Redrawn and renamed from the former Ottawa--Vanier riding following the 2022 redistribution, the constituency now incorporates the east-end community of Blackburn Hamlet, previously part of the Orléans riding. It encompasses a diverse collection of inner-city and suburban neighbourhoods including Sandy Hill, Lowertown, Vanier, New Edinburgh, Rockcliffe Park, Manor Park, Overbrook, and Beacon Hill, stretching east to Gloucester. The riding has a historically significant Franco-Ontarian population, though the francophone share has declined from over 60 percent in the early 1980s to under 40 percent today, as immigration and demographic shifts have transformed the district into one of Ottawa's most multicultural constituencies.

Candidates

Mona Fortier (Liberal)* first entered Parliament through a 2017 by-election. Before federal politics, she served as a senior director at La Cité college and sat on the board of the Montfort Hospital, a francophone healthcare institution central to the riding's identity. In cabinet, Fortier held portfolios including Minister of Middle Class Prosperity and President of the Treasury Board.

Dean Wythe (Conservative) is a New Edinburgh resident and federal policy adviser with a career spanning intelligence, national security, defence, and foreign affairs. A volunteer with organizations supporting Indigenous youth, Canadian Armed Forces personnel, and veterans, Wythe entered the campaign as a first-time candidate shortly after welcoming his first child.

Tristan Oliff (NDP) is an entrepreneur and founder of Roots of Purpose, a consulting firm for non-profit organizations. He previously served as press secretary to NDP leader Jagmeet Singh. His campaign focused on housing affordability, public transit funding for OC Transpo, and a guaranteed livable basic income.

Christian Proulx (Green Party) is a construction foreman who ran on the Green platform in the riding.

Marty Simms (People's Party) is an IT consultant who represented the People's Party in the contest.

About the Riding

Ottawa--Vanier--Gloucester is defined by its deep ties to the federal public service, its Franco-Ontarian heritage, and its role as a settlement corridor for newcomers to Canada. Vanier and Overbrook, once working-class francophone neighbourhoods, have become among the most ethnically diverse communities in the national capital, home to large Somali, Lebanese, and Haitian populations alongside longstanding French-speaking families. Rockcliffe Park and New Edinburgh, by contrast, are affluent enclaves that house diplomats, senior public servants, and some of Ottawa's most prominent residents. Sandy Hill, adjacent to the University of Ottawa campus, adds a student and academic dimension to the riding's mix.

The federal government is the riding's dominant employer, and public service issues--from pay system problems to return-to-office mandates--resonate strongly here. In 2025, the riding's political conversation centred on housing affordability, with rising rents and limited housing stock affecting both longtime residents and newcomers. Public transit reliability, francophone services, and the strain on social services from rapid population growth were recurring concerns. Despite the Conservative party's national gains, the riding's deeply embedded Liberal loyalties held firm, continuing a streak that has lasted the better part of a century.
