Which he only lost as they restructured his riding by adding a heavy lieberal section of Kanata north to the largely rural riding which skewed things a bit,
Not how it played out. The riding also shed a major suburb in the south end that definitely did not skew CPC.
In fact, as they always do when there are redrawing of ridings, Elections Canada released the poll by poll data from the previous election for both the new and old boundaries. In 2021, Poilievre took 49.9% of the riding, or 35,356 votes. Had 2021 been tallied under the new riding boundaries, he instead would have won 51.86%, or 36,534 votes. Both the LPC and NDP would have seen both a percentage and a vote count drop.
So, based on poll by poll results from 2021, the changed riding boundaries actually made Carleton lean slightly more Conservative than it was before. He simply lost anyway despite the slightly more downhill fight he had under the new, slightly more advantageous boundaries.
He also lost by a full 5+%, or 4,500 votes. It wasn’t close. Even if the shift in riding lean had been the exact opposite direction from what it actually was and HAD advantaged the Liberals (though it did not), he still lost by a margin several times any measurable change in votes in any direction. He earned an utterly honest loss.
