Context:

Ottawa’s Rideau Canal Skateway may be kept frozen through artificial cooling by embedding refrigeration pipes along a 900-metre downtown stretch, covering just over 10% of the ice while the rest would rely on natural conditions. The plan, assessed by the National Capital Commission, aims for carbon neutrality and would require funding from federal programs as it could extend the skating season—potentially tripling open days—though not before 2030. The Skateway, which stretches about 7.8 kilometres and draws tens of thousands of visitors, has been heavily affected by unusually warm winters in recent years. If implemented, the move could bolster Winterlude tourism and provide more predictable skating opportunities amid climate change. Ongoing feasibility and funding decisions will determine whether this approach advances in Ottawa’s iconic winter landscape.

Dive Deeper:

• The National Capital Commission is evaluating a feasibility study that would place refrigeration pipes in concrete to freeze a 900-metre segment of the Rideau Canal Skateway, effectively making the ice more resilient to warmer winters while the remainder relies on natural cold.

• Project cost is described as significant and likely in the millions; the NCC would seek funding from a federal program and explore other sources, according to Bruce Devine, the NCC’s senior manager of facilities and programs.

• If approved, the plan could triple the number of days the canal is open, but material implementation would not occur before 2030, indicating a staged rollout aligned with planning and funding timelines.

• The initiative emphasizes reducing carbon footprint and aims for carbon neutrality, including opportunities to recover and reuse heat within the system.

• Historically, the Skateway opened in 1971 and has grown into the world’s largest skating rink, offering about 7.8 kilometres of ice and drawing roughly 19,000 visitors daily in winter.

• Winterlude, Ottawa’s festival around the Skateway, typically attracts about 500,000 visitors over two and a half weeks, underscoring the project’s potential tourism impact amid changing climate conditions.
