Good education for most is a fairly modern thing (tons of boomers never finished highschool), Alberta is middle of the pack when it comes to post secondary education %.

You're jumping to a weird conclusion (and I know you don't believe it yourself and that you know I never said that, you're just trying to be a contrarian), that more education = less vote when it's the contrary, although it might happen depending on the options being offered (see Ontario reelecting Ford with an abysmal vote attendance). Today's tendency is more about people that didn't use to vote now going because of polarization and having parties that "speak to them" and it works because...

The most educated also tend to live in urban locations, since they're not spread out over the territory and the FPTP system not being proportional it means that cities lean left but rural/suburban districts (leaning right/more right than cities [see Toronto vs its suburbs]) represent a majority of the seats (see... well there's tons of elections where the party that wins a majority of the seats didn't get a majority of the votes or similar aberrations, like the Alberta conservatives losing 11 seats with 2% less votes but the NDP winning 15 seats with 11% more votes compared to the previous election).

There's also more options left of the conservatives than there are right of the conservatives in Canada, so the vote on the left gets divided more.
