Prime Minister Justin Trudeau to shuffle cabinet Friday

Prime Minister Justin Trudeau will shuffle his cabinet on Friday to fill the vacancy created by Jody Wilson-Raybould's departure over the SNC-Lavalin controversy.

A high-level government source tells CBC News that the shuffle will be small, involving no more than a handful of ministers. The source also saidthat the shuffle will be internal, and there will be no new ministers added to cabinet.

A second government source says some ministers have been called back to Ottawa to prepare for a Friday morning shuffle.

Trudeau has to fill Wilson-Raybould's post at Veterans Affairs. Defence Minister Harjit Sajjan has been acting in that role since Wilson-Raybould's resignation.

The Veterans Affairs ministrywas left vacant when Wilson-Raybould resigned from the position Feb. 12.

The former justice minister and attorney general of Canada only held the post for a month, having been moved there Jan. 14 after Scott Brison, the former president of the Treasury Board, retired from federal politics.

Wilson-Raybould told a parliamentary committee this week she believesshe was shuffled out of the Justice Department because she refused to buckle to pressure from 11officials from the Prime Minister's Officeand other departments whowanted her to give SNC-Lavalin a way out of bribery and corruption charges.

The Quebec-based engineering and infrastructure company was seeking a Deferred Prosecution Agreement, or DPA, that would allow the firm to avoid criminal prosecution, providing it met a number of conditions.
