The Lake Ontario 300 originated through the interest and vision of several single handed sailors at Oakville Harbour Yacht Club, now part of Oakville Yacht Squadron, and the Port Credit Yacht Club. Johan Pederson and his group envisioned a long distance race to challenge the skills of those who usually raced single-handed in the Lake Ontario Short Handed Racing Series (LOSHRS) or around the cans on their club’s race nights, or went to regattas such as the Lake Yacht Racing Association and sailed the Freeman Cup. Most, if not all, of these long distance races were for fully crewed boats. Johan realized that often the sailing done on Lake Ontario was by 2 people and racing double handed was a good way to improve and challenge skills.

​

Since then the Lake Ontario 300 has grown in both crew allowance and race length.  While there are still double-handed and solo entries, there are a number of boats that race fully-crewed.  In addition, every two year the Lake Ontario 600, that's twice around the lake, if offered.  2025 is one of those years and LOOR is pleased to offer the LO600 again this year.
