No, he didn't. This is the fantasy narrative that election reformers tell themselves.
The reality is that these efforts always blow up because there is never a consensus on what to change it to, and the general public just doesn't care.
And with the blowback they got for their efforts, they won't touch it again for at least another 15-20 years. The CPC would never even consider it. The NDP are as far from power as ever being essentially dead east of Ontario, and spotty through the rest of the country.
So people can sulk if they want to, but it's going to be status quo for the foreseeable future.
