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 (July 2020), the Liberal Party loses four points from 39% to 35%, the Conservative Party is up one point (variation smaller than moe), and the New Democratic Party climbs three points from 17% to 20%.
