When the PM wishes to, or is forced to, disolve his government he goes to the Governor General and announces his intention to do so. The GG then asks the leader of the opposition if he can form a government. If he can do so and choses to do so there is no election. The opposition leader forms a government. This is actually possible here as the Tories and Bloc together would have a majority of seats in the house. While this is unlikely it is still a possiblity. Most people think the opposition parties will go for an election hoping to pick up seats but they may choose to form a coalition government instead. All the parties are holding emergency meetings this weekend to decide what to do.
All: Thanks for the responses/descriptions. I have my fingers crossed that the leftist Canadian government will fall, just like the Clinton one did in this country.
