It’s nice to be first. And High Line Condos by Branthaven will be that – the first condo development on Mississauga’s Ninth Line Lands, an 870-acre strip that has been described by the city as “the final frontier” of undeveloped land in Mississauga. The lands will eventually be home to more than 4,000 new housing units, starting with High Line Condos’ six-storey, 205-suite building overlooking a protected forest.
