Seven principles chart a truly sustainable future for the St. Lawrence Seaway and the shipping industry as a whole. These principles outline the basis of how commercial navigation can benefit the people and economies of the Great Lakes region, ensure its own viability, and become a true steward for this spectacular, yet fragile, natural wonder. The Seaway and shipping industry is at the headwaters of challenging and exciting future. The decisions they make today will set a legacy that lasts well beyond the next 50 years.

1. Ships must not introduce or spread aquatic invasive species.
2. Climate change is a real threat, and proactive steps must be taken to meet this challenge head on.
3. Unnecessary and costly system expansion proposals must be abandoned.
4. Air emissions should be cleaned up for shipping to truly be the cleanest mode of transportation in regards to air pollution.
5. Work towards the elimination of all pollutants into the Great Lakes.
6. Minimize ice-breaking, especially in sensitive areas.
7. Citizen engagement and industry transparency should become the norm in Seaway governance.
