John Martin has fought the project on the grounds the city should have held an open competition on the plans for the park, rather than partner with an organization called Ottawa Sports and Entertainment Group.
The Supreme Court’s decision brings Mr. Martin’s series of legal appeals on the project to an end, city clerk and solicitor Rick O’Connor said in a note to the mayor and council.
Mr. O’Connor added the city will attempt to recover its legal costs from Mr. Martin on top of the $11,000 it is already seeking from the local resident.
Construction at Lansdowne, which is supposed to make it home to new sports teams, condominiums and stores, has already begun. It is scheduled to be completed by the end of 2015.
