The Provincial Parks

Buildings on Wellington Street Ottawa and the north side of the Mall on Sparks Street. How will Senate Bill S-203 impact the future of these federal properties?
Will Commissioner's Park on Carling always be public? The King and Queen of the Netherlands did not visit the park on their last visit to Ottawa. The people of Canada own or owned  Mile Circle, Gatineau Park and the Major's Hill land that was sold to the American Embassy. You are a gatekeeper/ a protector of Crown land, National Capital Commission.
Will the NCC remove the National Interest Land Mass designation from the Greenbelt, Greenbelt Research Farm, etc.
