Dear Hava, I quite agree

, pencil is - supersweet. Sublime, even.
In the interests of ever greater clarity, permit me to expand my answer somewhat re:11th hour nailbiting ...(forgive me if this is all or mostly already familiar to you as I understand the Knesset system is not dissimilar regarding the mechanics of seat distribution...) - ahem:
There are five parties worth tracking in this horse race - NDP, Conservative, Liberal, Bloc and Green. Of those, the Green has certainly earned it's fair share of merit badges, but it is only the other four that rise to the surface in such numbers as may determine the nation's fate.
There are 308 seats up for grabs when the music stops. We can give the Greens 1 of them for the sake of argument which leaves us with 307. In order to claim a majority, one party must occupy a total of at least 155 seats - meaning all other parties combining their will could not defeat the government on the floor of the house. This is also known as
'the divine right of kings' ...
Any party across the floor from the governing party can introduce a motion of no-confidence, which, if it has 50%+1 support of voting members, dissolves parliament, triggering an election. Conversely, a minority government need only count on as many loose seats as give them the 50%+1 to hold them up.
Practically speaking, this math works just as well when going through the formal dance moves of 'forming the government' ... The first party past the post is called on by the Governor General to form a government and is considered first past the post with as little as 1 measely seat more than any other contender. It's easy to see how, given a radically different distribution of seats than we are used to in Canada, a minority could be held by considerably fewer members than is usually the case here. It just so happens that our house has been eternally dominated by one or the other or both of the allegedly "sensible" parties. This is also the conundrum that leads many of the more circumspect among us to conclude that we really ought to abandon this first past the post SHIT. It leads to wildly unrepresentative results.
In a minority situation (fewer than 50%+1 out of 308), the governing party will always be dependent to a greater or lesser extant on the favour of some portion of the remainder of the house whenever budgets and/or no-confidence motions are at issue. When a minority government fails to maintain the support of a majority of the house it is alternatively possible for a formal coalition agreement to be struck between two or more parties who then present it to the Governor General and request that he/she grant them the opportunity to form a government. This is the thing that IGGY swears he would never invite Uncle Jack to do. This is the thing that prime sinister Harper says will cause cancer and and boils, not to mention rain doom and blight down upon us all and whatnot. God bloody forbid any self proclaimed servants of democracy and the people's will and welfare ought to pledge to cooperate or anything. That would be unthinkable.
When Harper and his scabby minions were found
in contempt by the speaker of the house, and parliament was dissolved, they set out on the campaign trail with 143 incumbents. He will most certainly come away with fewer than that many when the last ballot is counted. The burning question is HOW MANY fewer - and who will profit from his loss???
