Flowing through Ontario’s capital region, the Rideau River ( Ojibwe: Pasapkedjinawong) winds its way from Upper Rideau Lake, past historic Ottawa, and out to the Ottawa River. Along its course you’ll find scenic green spaces, paved pathways, and access points perfect for paddling or enjoying a riverside stroll. Nearby, the iconic Rideau Canal, a UNESCO world heritage site, is recognized as the oldest continuously run canal in North America. Together, the river and canal corridors deliver a peaceful, accessible slice of Ontario’s waterways and heritage.
