The electoral reform story is Trudeau wanted Ranked ballot in 2015-2016 when he won his first election and everyone wanted something else. So they ended up doing nothing.

Mostly true, except that the CPC didn't want anything. At all.

Neither the LPC nor the CPC really want a change, but the LPC would accept ranked ballots because they're everyone's second choice. The CPC is no one's second choice, and under anything other than FPTP they'd never be in office again.

The LPC would probably be permanently enshrined in government under ranked ballots, but PR (which everyone wanted) would see them never forming a majority ever again. 50% vote shares are incredibly rare in Canada; you have to go back half a century and even then they weren't common. But, majority governments with ~35% of the vote happen often, and the LPC and CPC would prefer to switch chairs every four to eight years than find themselves permanently exiled from power and having to negotiate with parties like the NDP, and appease an electorate that, if you look at it, is much more economically left-wing than the CPC or LPC are.

My issue with that is that, historically speaking, movement on electoral reform doesn't happen that often. If we can get something through, we had better make sure it's the best option that it can be because we are probably not going to revisit the issue for another 150 years. Further, when Trudeau ended up not moving on electoral reform, he had just recently won a strong majority. The calculus now is very different. Perhaps he can be pressured to accept the better system rather than his personally preferred system.
