The Wrights departed Edgewood three years later, leaving it vacant until it was purchased in 1884 by Octavius Henry Lambart, a son of the 8th Earl of Cavan.

Ahearn's daughter Lilias, who grew up in the house, would later become the châtelaine of Rideau Hall during her father-in-law Vincent Massey's term as Governor General of Canada.

The house was, with the assistance of the Canadiana Fund, restored and renovated in 1989 to reinstate historical features, as well as to upgrade the guest facilities.

Art and furniture from the National Capital Commission's (NCC) Official Residences Crown Collection are used throughout, as are pieces donated by the Lambart family.

However, due to renovation work at Rideau Hall that began in September 2017,[5] the house served from October 2017 as a residence for the Governor General at that time, Julie Payette.
