Key Findings Recent extreme weather events (in both summer and winter) demonstrate the vulnerability of Ontario's transportation networks to climate-related impacts. The flooding of roads and rail lines in July 2013 and the ice storm of December 2013 in Southern Ontario resulted in significant damage and travel disruption, but also spurred greater organisational awareness of the region's vulnerability to more frequent extreme weather. Multiple resilience-enhancing initiatives have been undertaken in the wake of these events by public agencies, particularly for roads and rail. Warming temperatures and changing precipitation patterns are expected to contribute to altered (increased or decreased) water levels in the Great Lakes basin, with implications for shipping capacity in the Great Lakes-St. Lawrence Seaway. Fluctuations over the past 20-30 years make it difficult to predict the direction of long-term change; however, freight transportation may shift to other modes should trends toward lower water levels throughout the Great Lakes occur again. The access period for winter roads in Northern Ontario is likely to decrease as a result of warming temperatures. This carries economic impacts for remote northern communities; a modal shift from truck to air transportation is likely to be necessary if significant investments are not made in more resilient road infrastructure in Northern Ontario. Practitioners in Ontario have begun to assess the vulnerability of their assets, and in some cases, adapt their infrastructure and operations in preparation for changing climate conditions. Efforts made by the Ontario Ministry of Transportation (roads and bridges), Metrolinx (rail), the Greater Toronto Airport Authority (aviation), and the Great Lakes-St. Lawrence Seaway Management Corporation (marine shipping) reflect a diversity of adaptive practices employed in Ontario.
Summary(Plain Language Summary, not published)
This report presents the current state of knowledge about climate risks to the Canadian transportation sector, and identifies existing or potential adaptation practices. The report includes six regional chapters and one urban chapter which reflect the different climate change impacts, vulnerabilities and opportunities across Canada. Adaptation approaches are discussed and case studies highlight adaptation actions and practices. A synthesis chapter brings together the report's key findings. Co-led by Transport Canada and Natural Resources Canada, the development of this report synthesized over 700 publications and involved 42 lead and contributing authors, and over 228 expert reviewers.
