OTTAWA -- Conservative Leader Andrew Scheer put the emphasis on caucus unity in his reveal of the official opposition front bench of critics Wednesday.

The roster includes both former leadership rivals, and gives files to MPs that backed Scheer in the leadership race. Absent from the lineup are Conservative MPs and former leadership candidates Brad Trost, whose social conservative supporters helped propel Scheer into the leadership seat; Kellie Leitch, who ran a divisive campaign that included a proposal to have newcomers to Canada take a values test; and Deepak Obhrai, who finished last among the 13 candidates who made it to the May leadership convention.

“Our Shadow Ministers are united, energized, and diverse,” said Scheer in a statement announcing the new critic lineup. The Conservative caucus will be coming back to Ottawa ready to take on not only Prime Minister Justin Trudeau’s government when Parliament resumes in September, but the Liberal Party in 2019, Scheer said.

The lineup of 42 Conservative MPs, counting Scheer and his House leadership team, is not gender balanced, but  includes 12 of the 17 women in the 97-member caucus.

“Ours is a movement that has room for every Canadian who believes in responsible government spending, strong borders, and a more affordable Canada for everyone,” said Scheer.

Opposition parties have critics for all the major files and cabinet positions, for the purpose of challenging ministers during question period, and to communicate how their party would approach policy differently than the current government.

The Conservative shadow cabinet lineup includes portfolios for a dozen MPs that supported Scheer during the leadership race, as well as spots for five of the candidates that ran against him for the party’s top job. A number of MPs kept the critic files they held under former interim leader Rona Ambrose, who is no longer an MP.

The full roster is as follows:

Ziad Aboultaif, MP for Edmonton Manning, Alta. is critic for international development.
