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 (May 2020), the Liberal Party loses three points from 44% to 41%, the Conservative Party climbs three points from 25% to 28%, and the New Democratic Party climbs two points from 15% to 17% (variation similar to moe).
