NDP Leader Jagmeet Singh has orchestrated a major overhaul of his front bench, reassigning critic roles for 13 MPs as he prepares to assume his seat in the House of Commons.

Singh has elevated Saskatoon MP Sheri Benson to deputy leader, where she will serve alongside Montreal’s Alexandre Boulerice, who is also the party’s Quebec lieutenant. Boulerice’s appointment was announced earlier this week.

Quebec MP Ruth Ellen Brosseau will take over as party whip, while former leadership hopeful Peter Julian has been appointed House leader and energy critic. Julian represents a riding in Metro Vancouver that includes parts of Burnaby, the terminus for the contentious Trans Mountain pipeline.

Karine Trudel, who represents a riding in Quebec’s Saguenay region, will take over as deputy House leader, while Vancouver East MP Jenny Kwan has been appointed deputy whip. Failed leadership candidate Guy Caron, who has served as the party’s parliamentary leader in Singh’s absence, will take over the foreign affairs post.

The shuffle comes on the heels of several high-profile NDP MPs announcing they will not seek re-election in 2019, including B. C.’s Nathan Cullen and Murray Rankin and Quebec’s Hélène Laverdière . Collectively, 13 of the 44 NDP MPs elected in 2015 are not running in this year’s vote.

It also comes as Singh prepares to enter the House after winning last month’s byelection in Burnaby South.

Other notable changes include Windsor-area MP Tracey Ramsey being named justice critic and Laverdière taking over a new role as special adviser to the leader on foreign affairs.

The rest of the changes are posted below:

Courtenay—Alberni MP Gord Johns is the critic for fisheries, oceans and coast guard

North Island—Powell River MP Rachel Blaney is the critic for veterans

Elmwood—Transcona MP Daniel Blaikie is the deputy critic for ethics

Victoria MP Murray Rankin is the deputy critic for justice

Port Moody—Coquitlam MP Fin Donnelly is the deputy critic for fisheries, oceans and coast guard
