We make boating easy

Trust Keswick Marina: Your Full Service Marina

We are located on beautiful Lake Simcoe and can be found off Cooks Bay 5 minutes down the Maskinonge River. We are just 45 minutes north of Toronto.

Looking for a motor? We have a variety of Mercury outboards in stock ready to go.

Today, under a new ownership for our former boaters and customers, we plan to continue to upgrade and improve the Marina and continue the tradition of high-quality service from our technicians, excellent customer service and dedicated employees.

We hope that you enjoy our Marina as much as we do.
