::::::trackratte, I still do not see any reliable sources.  The book by Bousfield and Toffoli, the first source, merely says, "Rideau Hall was her home, as much as Buckingham Palace in London or Holyroodhouse Palace in Edinburgh."  No explanation is made of what that means and no sources are pCrovided.  Also, the book is basically a fan book, with lots of pictures.  Certainly there are royalists who claim Rideau Hall is the Queen's official residence, but we need a reliable source to prove it.  And if there are no official records that it is the official residence, then how is it official?  Maybe it is the "unofficial" official residence?
