For the busy voters of Ottawa–Vanier, it's back to the ballot box again.

Since the last federal election in 2015, the Ottawa riding has seen a provincial vote, a municipal campaign and byelections at all three levels, if you count the part that makes up the city's Rideau-Rockcliffe ward.

Federally, Mona Fortier kept the seat for the Liberals in an April 2017 byelection, with more than 51 per cent of the vote.

The riding has elected a Liberal in every federal election since it was created in 1933.

Fortier faces:

Independent Joel Altman;

Former New Brunswick MLA and current policy adviser Joel Bernard for the Conservatives;

Former public servant and veteran Paul Durst for the People's Party;

Christian Legeais of the Marxist-Leninist Party of Canada;

Independent Daniel McHugh;

Overdose Prevention Ottawa co-founder Stéphanie Mercier for the NDP;

Derek Miller of the Rhinocerous Party;

Green Party candidate Oriana Ngabirano, who ran in that Rideau–Rockcliffe byelection and runs Ottawa's Healthy Transportation Coalition;

Feminist Canadian art historian Michelle Paquette of the Communist Party.

Candidates are included in this riding profile once they've been listed as a confirmed candidate by Elections Canada, chosen as the winner of a nomination contest or who were the chosen candidate by a party that got at least one per cent of the national popular vote in 2015.
