No harm to you at all, but I'm avoiding that site completely and advising everyone I work with and care about to stick with one of the other poll prediction sites like 338 if they have to use anything (scroll down for tl;dr).

Originally called polarispolls, smartvoting is run out of Polaris Entertainment.

When the smartvoting site was launched during the last Ontario election and started showing up on facebook/twitter/lemmy/etc, they didn't include specific information about their (proprietary) methodology, but they've put together a pdf for the federal launch. If anyone cares to read it, it's here.

Polaris Entertainment is made up of 3 people, afaict, and they're all podcast influencers. The youtube link here is a joint podcast they did 5 months ago. In it, the guy who claims he made the smartvoting website suggests twice just in this one interview that the NDP should bow out federally. Pretty standard Hot Take these days so not particularly sus, except that it's coming from a guy who made a vote recommendation website.

The person running the site used the royal WE a tonne when smartvoting was just one person during the Ontario election, and he now claims to have a "bipartisan data board." The site also now has someone they're naming as a general manager of the site, and she's said the NDP is running a harassment campaign against them, which is affecting everyone's mental health. Now, the same guy who claims he made the site says the reason he won't name any of the people on his new board and won't share any of his data is because of the NDP.

tl;dr: At best, smartvoting is a do-gooder project by someone trying to save us all from ourselves. With project 2025 rushing down the pipe and the mass media influence of the rightwing, I totally get it. People with fab intentions don't always come up smelling like roses, and I never require Purity from my left allies. But at worst, smartvoting could be another disinfo campaign, claiming to be anti-conservative, openly interfering with our elections to amplify the appearance of division between Canadians on the left, when we're already pretty cool with strategic voting and have been doing it when necessary for decades.

[disclaimer: this is the second comment I've left about being suspicious of this site since I made my lemmy account.]

There's also 338Canada's per-riding projection. There's the one by Eric Grenier too (CBC Poll Tracker).

One should check more than one to ensure there's no funny business going on.
