Just to remind everyone: Layton pulled this same stunt, toppling Martin's government.
The result was the loss of a number of progressive initiatives Martin's people were working on, the election of fucking Stephen Harper and the most conservative Canadian political landscape since Borden. Science was suppressed, lslamophobia went from being a dogwhistle to a bullhorn, we narrowly avoided economic catastrophy. Harper even fucked with the Census in an attempt to remake Canada.
A lot of dippers really idolized Layton, but honestly he was a shameless opportunist and I don't forgive him for giving us almost a decade of Harper.
And Singh is pulling the same fucking stunt.
