2015 Federal Election

[plam]

I don’t think that’s correct; the Liberals don’t necessarily favour one system over another – they’ll be appointing a team of people who will research what system is best, by talking with Canadians and then will come back to the house with their findings to vote on what system they should go with.

That's right.  All they are saying is that this will be the last PPTP election, and that they will introduce the legislation within 18 months.

Incidentally, one of their other policies is "a truly independent Senate not based upon partisanship or patronage".  It's a good concept, and hearkens back to the original days as a chamber of "sober second thought" some 140 years ago.  And it doesn't require a constitutional amendment.  But I'm not sure how they can actually make this work in practice.

I can imagine ways to have such a Senate, and there's got to be some countries where it's the case. But I don't know of any.

It is, however, consistent with Justin Trudeau booting all of the Senate Liberals from being Liberals though.
