Along Lake Ontario's western shore, Lakecourt Marine comprises approximately 4.6 acres across three adjoining parcels, offered as one holding. With approximately 352 feet of Lake Ontario shoreline and 562 feet of Grimsby Harbour frontage, and a sheltered private harbour, the property combines marine infrastructure, two residences, and substantial waterfront lands.With approximately 2.3 acres identified as developable land, municipal services in place, and Marine Commercial (MC) and Residential Detached 2 (RD2) zoning, the property presents three distinct directions for ownership and investment: continued marine operations, future development, or a private waterfront estate.The harbour and existing infrastructure support the potential renewal of marina operations and complementary marine businesses. The acreage and zoning invite consideration of residential development, boutique hospitality, wellness, and recreational uses, subject to municipal approvals. Alternatively, the shoreline, privacy, and existing homes lend themselves to a waterfront estate or multi-generational retreat.Improvements include a pre-war two-bedroom cottage bungalow with detached garage, a three-bedroom, two-bathroom Viceroy-style raised bungalow, and three accessory buildings. Municipal water, sanitary and storm sewers, and electrical services are in place.Rooted in Grimsby's commercial fishing history, the lands later became a family-operated marina. Still operating on a limited basis, it has approximately 60 existing boat slips designed for vessels up to 42 feet. The protected harbour remains central to its character and future.Within reach of the Greater Toronto and Hamilton Area and Niagara's wine and tourism region, Lakecourt Marine remains one of the few privately owned marina properties along this stretch of Lake Ontario, offering potential for investment, redevelopment, or continued marine use.
