Sorry, that link just covered the first proroguing of the government in 12 months. The second case was that the Governor General of Canada – the Queen's person in the Canada, appointed by the Queen – was this month where the government was prorogued for two months to stop budget talks. I'm looking for a good link that sums everything up, but the move has been controversial and it's really looking like the Harper government in Canada is leaning on proroguing to stop things from happening he doesn't like. Here in the US, we have nothing, absolutely nothing, so contrary to democracy. If you Google Canada proroguing you'll get a bunch of current articles about, y'know, various protests and stuff about the proroguing and they'll talk about the crisis from which you'll get the salient details – but on a quick search I wasn't able to find something that summed it all up together.
