The Conservative Party of Canada decided to hold a national party convention on October 11, 1927, to choose a new leader and set a new party platform. This would be the first time the Conservatives would hold such a convention.
The Conservative convention was held in Winnipeg, Manitoba, and there were six candidates at the start. R.B. was one of them. It took two ballots to declare a winner, who needed to receive a majority of the votes. R.B. was that winner. After the results of the second ballot were read, each of the other candidates made their way to the microphone to officially withdraw from the race in the old tradition of making the vote unanimous. Besides selecting a leader, the party also reshaped the planks of its platform and adopted twenty-two resolutions marking the change perceived in the political landscape.
As the leader of the federal Conservative party, R.B. was also now the leader of His Majesty's Loyal Opposition in the House of Commons. He had a huge job ahead of him. He set out to rebuild the party into an efficient political machine that could lead the country.
