Nestled within Ottawa’s Greenbelt, the Mer Bleue Bog offers visitors a unique opportunity to explore one of Canada’s most significant and ancient wetlands. Spanning more than 3,300 hectares, Mer Bleue is a remarkable boreal-like sphagnum peat bog that serves as a crucial habitat for rare plant and animal species, while also providing a glimpse into the post-Ice Age landscape of Eastern Ontario. The natural beauty, ecological importance, and well-maintained boardwalk trails make Mer Bleue a peaceful destination for bird watchers, hikers, photographers, and anyone seeking to connect with nature close to the city.
History of Mer Bleue Bog
Mer Bleue, French for “blue sea,” is believed to have formed approximately 7,700 years ago in an ancient channel of the Ottawa River, created by the retreat of the Laurentide Ice Sheet. Its unusual acidic water and peat soil create a distinctive environment supporting hardy boreal flora and fauna typically found much further north.
In more recent history, during World War II, the Royal Canadian Air Force used the area as a bombing practice range— a testament to its rugged, untouched character at the time. Since being recognized for its ecological significance, Mer Bleue has received conservation designations including becoming a Ramsar Wetland of International Importance in 1995 and a Natural Area of Scientific Interest in 2011. Today, it is managed by the National Capital Commission, ensuring protection and public accessibility.
