Well, actually, The Queen won't be living there - the house is for Canadian Consul General Stephen Brereton. But you already know that because you read the article
And, since you did, you probably saw that is was prominently covered in the press - not on TV, but on the front page of the BN City Section. Even gave the exact address. Also metioned the price - which, btw, is probably double the house's actual value. (Dumb Canadians.)
And, also btw, if I rent a property to someone who doesn't take possession and start paying rent until July 1st, I can do whatever the fk I want with my property between now and then - including media tours, if I so please.
