This is my estimate of Canadian vote intention based on polls listed on Wikipedia. The predictions for voting intention assume that the polling errors are the same both pre- and post- 2021 election. That may or may not be true, but I suspect that polling errors are correlated between these periods.

Using polls up to and including August 16, 2022, the CPC is ahead. Estimated vote intention for August 16th was:

Party Vote share 95% bounds
LPC 32.2% (29.5%, 35.1%)
CPC 34.4% (32.0%, 38.1%)
NDP 17.6% (15.7%, 19.6%)
BQ 7.8% (6.0%, 8.8%)
GPC 3.4% (2.5%, 4.6%)
PPC 3.3% (1.3%, 5.0%)
Other 1.4% (0.8%, 2.1%)

Ontario vote intention

Last updated: August 16, 2022

A few months ago, Ontario held a provincial election. Altough no election will be held for 4 years, below is my estimate of Ontario vote intention based on polls listed on Wikipedia. Because there are fewer polls here than at the federal level, the underlying vote intentional is much more impercise. Nonetheless, we can see the PCs are well in the lead.

Party Vote share 95% bounds
CPC 41.6% (32.6%, 50.7%)
NDP 24.9% (22.0%, 32.4%)
Liberal 20.1% (24.8%, 31.7%)
Green 6.7% (4.5%, 10.5)
Other 5.8% (3.9%, 7.6%)
