Originally, LaSalle Park Marina was a bustling dock, transferring concrete to and from the Cooke Concrete Block plant just up Waterdown Road. Today, LaSalle Park Marina supports 219 boat slips and is managed by volunteers of the LaSalle Park Marina Association. The marina also provides several community outreach programs including Sailing for the Disabled and Sea Cadets. In addition to being a source of community development, the marina supports fish and wildlife populations, most notably the trumpeter swan; LaSalle Park has the largest concentration of trumpeter swans in Ontario during the winter months. The Marina currently has plans to reconstruct the wave break that protects the boats from the Harbour’s waves, to build an additional 120 slips and add year-round electricity that would power ice prevention devices in the open water.
