According to CBCNews:
The Queen Elizabeth portrait is out and twin paintings by Quebec modern master Alfred Pellan are back in.
Former Liberal foreign affairs minister John Manley…said displaying such a large portrait [of the Queen] in such a prominent location sent “the wrong message.”
In 2011, then foreign affairs minister John Baird instructed that the pair of historic paintings by celebrated Quebec modern master Alfred Pellan be replaced by a 2002 portrait of the Queen.
The change was ordered before the visit of Prince William and Kate in June 2011.
