About the Property
Known locally as “The Big White House in Port,” this historic Port Dalhousie mansion is a rare blend of coastal grandeur and modern luxury. Set on 109 feet of private Lake Ontario shoreline, this three-storey estate—originally dubbed “The Breakers”—was fully restored in 2017 and reimagined for entertaining, relaxing, and taking in cinematic lake views from every floor.
Inside, the 4,400 sq. ft. home features a professionally designed interior with smart home amenities, in-floor heating, and a chef’s kitchen that flows into formal living and dining spaces. A show-stopping third-floor home theatre boasts a 120-inch screen, wet bar, and panoramic water views, while a 500-bottle wine cellar adds character and charm with cherry wood cabinetry and cobblestone floors.
Outside, the property includes a heated garage, new landscaping and stonework, and composite decking. The location—steps from Lakeside Park beach, Port Dalhousie Yacht Club, the pier marina, and local shops—cements this home as a true Niagara gem.
