This page contains all the information required to understand the significant work involved in the delimitation of Québec’s electoral map.
Every two general elections, the Commission de la représentation électorale must review the delimitation of electoral divisions to ensure the effective representation of electors at the Assemblée nationale. Anyone interested in the matter can send us their comments on the reviewed proposal up until the final decision is made.
Official resumption of the process
On May 2, 2024, the Assemblée nationale du Québec passed the Act to interrupt the electoral division delimitation process. Citizens and various organizations, including the Conseil des préfets et des élus de la région des Laurentides, asked the court to invalidate the Act. Pending judgment, on December 5, 2024, the Superior Court of Québec allowed the Commission de la représentation électorale to finalize its second report (in French) without making it public or tabling it at the Assemblée nationale.
On May 29, 2025, the Superior Court dismissed the plaintiffs’ case (in French). However, it was appealed. On December 1, 2025, the Court of Appeal of Québec ruled in favour of the plaintiffs (in French) and declared the Act to interrupt the electoral division delimitation process unconstitutional. As a result, the Commission de la représentation électorale was able to table its second report, which presents its reviewed delimitation proposal, at the Assemblée nationale.
In this second report, the Commission de la représentation électorale presents a reviewed proposal for the delimitation of Québec’s electoral divisions. This document follows the public hearing the Commission held in the fall of 2023 concerning the delimitation proposal presented in its preliminary report.

The delimitation of electoral divisions proposed in the preliminary report aims to ensure the effective representation of electors. This principle is linked to the relative equality of the vote of electors and respect for natural communities.
The preliminary report was the subject of a public hearing in the fall of 2023. It was also submitted to the Commission de l’Assemblée nationale for consideration during a hearing held on February 13, 14 and 15, 2024.

This table provides the electoral population of each electoral division as well as the deviation from the provincial average of electors per electoral division.
As part of the electoral map revision process, the electoral population is rebalanced between divisions to ensure fair and equitable representation of electors.
