The document discusses Canada's approach to marine spatial planning and environmental protection through ecosystem-based management of its marine waters. It outlines Canada's integrated ocean management process, including defining planning areas, identifying key ecosystem components, and setting conservation objectives. It also provides examples of three marine protected areas - Eastport, Gilbert Bay, and The Gully - and lessons learned from Canada's marine protected area planning process. Moving forward, Canada is focusing on developing a national network of marine protected areas to further advance ecosystem-based management implementation.
