A no-confidence vote in the Canadian parliament today means Canadian citizens can look forward to another election, their fourth in seven years.
The vote, engineered by the opposition Liberal Party and backed by two other opposition parties, triggers an election expected in early May.
The move stemmed from a ruling on Monday that the minority government was in contempt of parliament.
But the Conservatives are thought likely to keep power in a May election.
With the House of Commons adjourned, Mr Harper on Saturday will ask Governor General David Johnston to dissolve parliament.
Following that, an election will be held after a minimum 36 days of campaigning. Canadian analysts expect it will be called for the first week in May.
Mr Harper's Conservative Party holds 145 seats in the dissolving parliament, shy of a majority of the 308 seats.
Recent polling suggests the Conservative Party holds a lead at the start of the campaign, with the Liberal Party in second, the New Democratic (NDP) Party third and the Bloc Quebecois, which campaigns only in Quebec, fourth.
The Conservative Party is likely to emerge from the May election in power, with some polls indicating it could even gain seats.
After the vote, Mr Harper said he suspected the forthcoming election, the country's fourth in seven years, would "disappoint" most Canadians.
Analysts say Canadian voters have shown little desire for an election, although Mr Harper's minority government had set a record for its tenure.
