About grand harbour

Nestled within the heart of Lagoon City, Grand Harbour Marina is a landmark destination set against one of Ontario’s most distinctive and picturesque waterfront communities. Known for its winding canals, direct access to Lake Simcoe, and vibrant boating culture, Lagoon City has long been celebrated as “Ontario’s Venice”—a place where life flows effortlessly between land and water.

For generations, this marina has served as a gathering place for boaters, families, and visitors drawn to the beauty, tranquility, and sense of community that defines Lagoon City. From leisurely canal cruises to open-water adventures on Lake Simcoe, the marina has always been central to the lifestyle and rhythm of this remarkable destination.

Today, Grand Harbour Marina is entering an exciting new chapter.

With deep respect for the marina’s history and its importance to the community, our vision is to thoughtfully restore and elevate the property—bringing it back to its glory days while reimagining what a modern marina experience can be. Our focus is on delivering a truly luxury waterfront lifestyle: enhanced services, elevated amenities, and a welcoming environment that reflects the sophistication and pride of ownership our members expect.

Every improvement we make is guided by a simple philosophy—honouring the past, investing in the future, and creating an exceptional experience for our boaters. At Grand Harbour Marina, the water is more than a view; it’s a way of life, and we are committed to making it unforgettable.
