An Elevated Waterfront Experience
Our Marina Experience
What truly sets Grand Harbour apart is its exceptional setting within Lagoon City, Ontario’s only canal-front boating community. With more than 16 kilometres of beautifully engineered, man-made canals, the area offers rare direct-to-dock access for homes and cottages throughout the community—earning Lagoon City its reputation as the “Venice of Ontario.” These serene waterways provide seamless access to Lake Simcoe, creating a uniquely effortless and immersive boating experience.
More than a traditional marina, Grand Harbour blends the charm of a resort-style neighbourhood with comprehensive marine services and amenities. Boaters can step from their back door to their vessel or enjoy unhurried cruises along the picturesque canals that weave through the community. Surrounded by natural beauty and a vibrant boating culture, with convenient access to fuel, amenities, and waterfront dining, Grand Harbour delivers a refined waterfront lifestyle that is both distinctive and truly memorable.
Your Boating Paradise
Lagoon City Experience
The experience surrounding Grand Harbour is unlike anywhere else in Ontario. Set within the heart of Lagoon City, this extraordinary waterfront destination is defined by more than 16 kilometres of navigable canals that connect homes, docks, and pathways—earning the area its iconic reputation as Ontario’s Venice.
Located along the eastern shore of Lake Simcoe, the community blends the ease of small-town living with the energy and refinement of a resort-style waterfront lifestyle. Each season offers its own rhythm: summer days spent boating, swimming, fishing, enjoying sandy beaches, and cruising the canals, followed by winter adventures including snowmobiling, ice fishing, and scenic trails.
With its distinctive canal layout, vibrant boating culture, and a full-service waterfront destination at its centre, the lifestyle at GRAND HARBOUR is centred on connection—to the water, to the community, and to a way of life that feels both relaxed and elevated. It is a place to arrive, unwind, and create lasting memories on the water.
