Canada has the world’s longest coastline, over 243,000 kilometers, and holds one-fifth of the world’s freshwater, with over two million lakes and 8500 rivers draining into five Ocean watersheds. The country’s relationship with the Ocean is shaped by regional, historical, economic, cultural, and linguistic perspectives, all contributing to the diverse ways in which people understand, value, and care for the Ocean. However, the term ‘Ocean Literacy’ does not resonate with all people who live in Canada, especially for inland and Indigenous communities. For those living inland, it may feel less relevant; for Indigenous communities, it may be seen as a modern intervention that does not fully capture their ways of knowing. This chapter shares the efforts of the Canadian Ocean Literacy Coalition (COLC)—now known as the Centre for Ocean Literacy Collaboration—which launched in 2018, to conduct a national study to assess the state of Ocean Literacy, identify gaps, barriers, and enablers, and make recommendations. The study’s multi-regional, multi-sectoral methodology is discussed, leading to the co-development of the Canadian Ocean Literacy Strategy in 2021, making Canada the first country in the world to do so. The chapter highlights the Strategy’s focus on a collaborative framework for action, while respecting regional and cultural diversity, as well as addressing the limitations of an imperfect term. Next, the National Strategy Impact Measurement Program, which tracks progress and impact of Key Initiatives, such as Ocean Week Canada, is explained, including impact themes, metric families, representation, and measurement limitations. The chapter concludes with a reflection on the coalition model, lessons learned, and future steps to advance Ocean Literacy in Canada and globally.
