The Dominion Building in downtown Charlottetown has been sold to developers from Halifax.
A deal was signed Friday to sell the former post office edifice to a company called Rank Incorporated, the developer behind a proposed new convention centre in Halifax.
Plans for the Dominion Building are said to include retail and commercial space.
Canada Lands took over the building in 2007 and put it on the market late last year.
What Rank Inc. paid for the Dominion Building has not been made public.
The building has been vacant since 2008, when the last government employees moved out.
