Rideau-to-Rideau Cultural Landscape Study

ERA Architects was retained by the National Capital Commission (NCC) to lead the Rideau-to-Rideau Cultural Landscape Study, a foundational component of the NCC’s Master Concept Plan for the Rideau-to- Rideau Waterfront Promenade. The study area spans approximately two kilometres of the Ottawa River (Kichi Zibi) shoreline between Parliament Hill and Rideau Hall, adjacent to nearby ERA projects Kìwekì Point and the Centre Block Rehabilitation on Parliament Hill.

Situated on the traditional, unceded territory of the Algonquin Anishinabe Nation, the area is layered with ongoing Indigenous relationships to land and water, colonial military and industrial uses, and successive phases of capital planning and municipal development. The analysis considered how topography, ecology, and human activity catalyzed cultural practices and patterns over time.

ERA’s approach emphasized understanding the landscape as experienced from the water, recognizing the Ottawa River as a primary cultural corridor and interpretive lens through which the area’s evolution and significance can be interpreted. This perspective reinforced the river’s essential role in shaping identity, movement, and meaning within the Capital Core.

Central to the methodology was a comprehensive mapping and spatial analysis process, synthesizing archival research, historical cartography, and contemporary landscape data. This work revealed patterns of change, use, and continuity, informing the identification of character-defining attributes, heritage values, and distinct cultural landscape areas.

The study culminated in a Statement of Significance and a heritage conservation framework, including area-specific conservation goals and guidelines to support future planning and design initiatives. Designed to balance conservation and renewal, the study complements NCC policy tools and sustainability, design, and circulation guidelines while supporting the integration of Indigenous perspectives, ecological stewardship, and long-term public use.

The Rideau-to-Rideau Cultural Landscape Study provides a cultural foundation for the evolving Rideau to Rideau corridor and contributes to a deeper understanding of its role within the broader cultural and natural identity of Canada’s Capital Region.
