Great Lakes St. Lawrence Seaway System Directory

The Great Lakes St. Lawrence Seaway System Directory is one of the premier marketing tools we use to attract new business to the System. This comprehensive publication is highly effective and used daily as an information and promotional resource. It is available in all formats – high quality print, interactive digital and as a free mobile app. The 2020 edition follows the successful pattern established in previous editions. It will include over 70 full-color pages of information about ports, carriers and shipping-related businesses in the Seaway System, together with feature stories on key industries, technical facts, shipping trends and market conditions.

We are pleased to announce that Harbor House Publishers, well-known to most of you as the publisher of Great Lakes/Seaway Review magazine, will once again publish the Directory. We value their experience and knowledge of the marine industry, and are confident they will produce another excellent guide to the Great Lakes St. Lawrence Seaway System.

The Directory is used around the world to promote the Great Lakes St. Lawrence Seaway System, with over 52,500 print, digital and mobile downloads annually. Please visit to view the Directory.

There are two digital options available to you:

Ellen Trimper from Harbor House Publishers will soon be contacting ports and industries in the United States and Canada to discuss your advertising options for the Directory. The success of this special publication depends largely upon your participation. We would appreciate any assistance you can provide to Ellen when she contacts you. She can be reached at or call (800) 491-1760.

Thank you for your cooperation and assistance in promoting the Great Lakes St. Lawrence Seaway System as the most reliable, efficient and environmentally-friendly waterway in the world.
