Key Findings Flooding associated with extreme precipitation events has been driving climate adaptation efforts for transportation in the Prairies, and increasing frequency and intensity of such events is a key future concern. Flood-control strategies (e.g., expanded and enhanced culvert programs to reduce washouts, impermeable runway treatments) represent key adaptations for rail operations, airports (particularly in the northern Prairies), and roadways in the region to date. The high variability inherent in the climate of the Prairies means that adaptation in the transportation sector is likely to involve both reactive and proactive measures. Given climate uncertainties and cost challenges in the transportation sector, decision-makers in the Prairies tend to view operational adaptations on a case-by-case basis. The importance of long-term planning for infrastructure (including zoning requirements), however, is illustrated by damage sustained in recent flood events in southern Alberta and Manitoba. Efforts are underway to address the vulnerability of winter roads to increasing temperatures in the Prairies. While routing changes and technical adaptations have contributed to longer operating seasons in recent years, further projected warming may require more significant adaptations (i.e. the construction of all-weather roads). Thawing of permafrost in the Hudson Bay Lowlands will continue to challenge the operational viability of rail in the region. Since the track was laid in the 1930s, geotechnical engineers have made costly efforts to stabilize the rail bed. Over the long term, thawing permafrost is likely to increase stabilization challenges, although disappearing permafrost could also improve the viability of some techniques.
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.
