we are very much in a 3 party system which allows a cooperative attitude towards minority governments than spitefilled shitfests that a 2-party gov would have (seriously look at the US). in fact in a 2 party system there would never even be minority governments at all (would you really want a majority gov all the time).
mind you, i'm pro minority gov't since i see them as being a proper execution of representative parliament and it offers more scrutiny and accountability to active government.
Minority governments under FPTP only happen because of regionalism though and a fractured opposition. The last time it almost happened in the UK, for example, was because Labour was considered shit and Scottish Nationalism was on the rise. Then Nick Clegg sold his soul and we all know how that turned out.
For it to happen here again, we would either need the Bloc to surge and capture most of Quebec's seats, or for some other province to feel slighted and vote for their own party that has no affiliation to one of the three national brands. So unless Ontario decides to start separation movement and creates the Ontario Party, I'm not sure what's supposed to happen.
The American political institutions realized long ago that being the third party in a FPTP system means irrelevance and division, which is why they have either disappeared or have turned into funky party organizations like the Minnesota Democratic–Farmer–Labor Party, which represents the Democrats of course, but as the name suggests, is a coalition.
Even in Australia, which has AV for the House, they've basically found themselves in a defacto 2-party system because everyone realised that they would be better off working with other parties through mergers. I mean the centre-right government is literally called the Coalition after all.
Now would I prefer a Liberal government propped up by the NDP? Sure. But right now the only way that will happen is if Trudeau offends Quebec enough for the Bloc to steal their votes again, and I don't know if having yet another resurgent era of sovereignty is worth it.
(Of course, you just have to look at the Knesset to see that minority governments governed by coalitions can turn into a shit show as well)
