Mere weeks following the general election, Harper's Conservative government launched a series of controversial economic proposals, spurring the three opposition parties — the Bloc, the Liberal Party and the NDP — to begin talks regarding a coalition to defeat the Conservatives in a vote of non-confidence. On 1 December, the three party leaders committed, in an historic accord, to introduce a non-confidence motion as early as the following week. Ultimately, Harper's request to prorogue government was granted by Governor General Michaëlle Jean and the durability of the coalition became questionable.
