Currently led by interim leader Patrick Paquet since November 8, 2022, it has been registered with the Directeur général des élections du Québec since June 8, 2017.
As the 2017 Quebec municipal elections approached, some voters came out against the bus rapid transit project proposed by Mayor Régis Labeaume.
Frédérick « Fred » Têtu, a Right-wing climate-skeptic and philosophy teacher, ferociously critiqued initiatives aimed at encouraging modes of transportation other than by car.
[2] To lead the party, Têtu approached Jean-François Gosselin, former Action démocratique du Québec MNA in 2007.
When Mayor Régis Labeaume announced a project to build a tramway for 2026, the party weakened its policy against public transit.
Six members of the party executive, including president Serge Marcotte and general-director Nancy Piuze, resigned on April 3, 2019.
In May 2021, Gosselin announced that for the 2021 Quebec City municipal election, Patrick Paquet would run in Neufchâtel-Lebourgneuf and Stevens Mélançon in Chute-Montmorency-Seigneurial.
Mercier promised to evolve the party, collaborate with new mayor Bruno Marchand, but that he would watch his administration closely.
[9] By the end of November 2021, Québec 21 lost one of its members, as Stevens Mélançon left the party and chose to sit in the council as an Independent.
