If the polls hold up and the Conservative win people should realize that the LIberal’s could have changed things dramatically by implementing Voting Reform but refused to do so

They don't care.

If they lose, they know they'll be back in, depending on how bad the Conservatives do, on four to eight years, likely with a majority. Both parties are quite amenable to a periodic chair-switch.

However, if they had put through electoral reform, they'd never get another majority again. They'd have to share power with other, likely left-leaning, parties, which they wouldn't like. It would mean less power, less exclusive access to donations and reciprocation, and the ire of their donor class, who very much don't want to see a goverment that aligns with Canadians instead of the investor class.

The Liberals would ratther lose every seat in parliament than implement electoral reform.
