Prime Minister Stephen Harper's decision to move Peter MacKay into defence from foreign affairs, which former Industry minister Maxime Bernier will take over, and Bev Oda from heritage to international co-operation, has resulted in numerous staff changes in the ministers' offices. While Dan Dugas remains Mr. MacKay's press officer and John MacDonell will stay on as his chief of staff, Simon Burke's one-year tenure as senior policy advisor has come to an end. Carole Piovesan, who served for a time as Mr. MacKay's policy advisor at Foreign Affairs, will take over in his stead. Isabelle Fontaine moves with Mr. Bernier to Foreign Affairs as his spokeswoman, while Nadia Burger, who has served as DFAIT's deputy director of the East Asia division, becomes his senior policy adviser. Aaron Gardiner, former Defence minister Gordon O'Connor's former chief of staff, takes that role in Mr. Bernier's office, replacing Michele Austin. At CIDA, Joanne McNamara remains Ms. Oda's chief of staff and Jean-Luc Benoit moves maintains his position as the minister's spokesman. Officials could not say who Ms. Oda's senior policy advisor is as the team is still being assembled.
