Meanwhile, Transition Montréal leader Craig Sauvé and Action Montréal's Gilbert Thibodeau secured about 19% of the vote collectively.
Originally from Chile, Martinez Ferrada is now the first mayor of Montreal from an immigrant background. Her win brings a major political shift to the city, while voter turnout sat at 36.5%, according to the official results.
But while the city picked a new mayor overall, the vote looked very different depending on where you live. Some boroughs went all-in for Martinez Ferrada, others stuck with the party of Valérie Plante, and a few races were surprisingly close.
While some votes are still being tallied, here's a borough-by-borough look at who different neighbourhoods cast their ballots for.
