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 down one point (variation smaller than moe), the Conservative Party loses three points from 28% to 25%, and the New Democratic Party climbs three points from 17% to 20%.
