The Green party won 1 seat in the last Canadian federal election. They then won another seat in a by-election this year. They then had a sitting MP cross to the Green party, bringing their total in the current Parliament to 3.
What are their prospects for the upcoming election? This is how things look right now in the latest internal official Canada 2019 campaign.
You can see that they’re leading in 5 ridings. You can also see their riding strength is concentrated in B.C. (where they already have 2 ridings) and P.E.I. (where they almost won the Premiership recently).
(Note these numbers don’t account for the recent new MP in Quebec, which could make them competitive in another seat.)
If the Greens run a good campaign, given these numbers, it seems they could win double-digit seats in 2019.
