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 ±2.5%, 19 times out of 20 (for entire sample only) around the 50%-mark.

If we compare these national numbers with the previous poll from Léger (June 2020), the Liberal Party is up one point (variation smaller than moe), the Conservative Party remains stable at 28%, and the New Democratic Party loses two points from 19% to 17% (variation similar to moe).
