Dominique Ollivier is a Montreal City Councillor for Vieux-Rosemont with Projet Montreal, elected in 2021. Before politics she chaired the Office de consultation publique de Montreal (OCPM), the city's arms-length public-consultation body. Served briefly as President of the Montreal Executive Committee under Mayor Valerie Plante from November 2021 to October 2023 before resigning over a controversy about an OCPM expense claim from her previous OCPM tenure that included a $4,300 hotel stay during a 2019 trip. Continues as a sitting councillor and the first Black woman elected to Montreal City Council.
