About this Quebec poll from Synopsis Recherche
This Quebec sovereignty poll was fielded by Synopsis Recherche in September 2026, with a middle field date of September 12, 2026. The poll collected data from a total sample of n=1,000 Quebec respondents via an online panel.
The margin of error for an online sample is not applicable.
For comparison purposes, a random sample of this size would yield a margin of error [moe] of ±3.1%, 19 times out of 20 (for entire sample only) around the 50%-mark.
If we compare these numbers with the previous poll from Synopsis Recherche (August 2026), opposition to Quebec sovereignty loses three points from 63% to 60% (variation similar to moe), and support for Quebec sovereignty climbs two points from 29% to 31% (variation smaller than moe) among all respondents.
