Paul Martin has announced June.28 as the election day. Four major parties r fighting for the seats in the Parliament. The party which gains more seats, will introduce the Prime Minister, as far as I'm concerned. It means Martin could be a very short-time Prime Minister. But I don't know why it's like this!
