The CPC needed to be humiliated in the last election. That was the only way for moderate conservatives to regain their voice in Canadian politics. They lost it to populist conservatives, who took over the Conservative Party of Canada, when Stephen Harper was elected leader of the CPC.
As a result the CPC has been drifting further and further to the right until they can now be truthfully called Maple MAGA.
The last election was a golden opportunity to change that. All moderate conservatives had to do what to hold their nose, for this one election, and vote Liberal. If the CPC would have been reduced to less than 100 seats then the grip of Maple MAGA could have been broken. The irony is by doing so moderate conservatives would have been voting for one of their own. Make no mistake, Mark Carney would not have been out of place in Brian Mulroney's cabinet and he would have blended into a Joe Clark cabinet very well.
However, moderate conservatives just could not bring themselves to do that, at least not in large enough numbers to make a difference. The end result is the CPC lost but not badly enough for them to believe that they actually need to change and renew their party. Pierre Poilievre will win his by-election and he will continue to rule his party much like he did before the election.
Or, he could still lose his grip on the party but his replacement will not be any different from him. Maple MAGA has been emboldened by the increase in the CPC seat count so no matter who winds up leading them into the next election their differences from Mr. Poilievre will be nothing more than differences in packaging and style. They will still be Maple MAGA.
Moderate conservatives forfeited their voice in Canadians Federal politics for at least a decade and probably longer.
