Key Findings Climate change will affect the natural environment of all regions of Quebec and may damage or cause service interruptions to transportation systems. Nunavik has, and will continue to, experience significant climate change and will have to deal with the thawing of the permafrost on which transportation infrastructure is built. In eastern Quebec, the increase in relative sea level, loss of ice cover, freeze-thaw cycles and changes to storm systems will contribute to further erosion of riverbanks and shorelines. For all regions of Quebec, Surface runoff management is a challenge. The vulnerability of transportation systems to climate change varies according to regional characteristics, the type of infrastructure and its use. The condition and maintenance of infrastructure, the current use of transportation systems and the availability of alternatives during service interruptions, are all factors that influence the scope of climate change impacts on transportation systems. Extreme weather events represent one of the greatest risks for the transportation sector, in all the regions of Quebec. Episodes of heavy rain, floods, coastal erosion and landslides will affect both the transportation infrastructure and the mobility of people and goods. The isolation of communities that depend more on one particular mode of transportation could be accentuated by extreme weather events. Although thawing permafrost is the most significant climate change impact affecting Quebec's northern communities, similar to the northern territories, rising temperatures are also reducing winter mobility due to shorter freezing periods. The shorter winter season and loss of ice cover make access to the region and its resources more difficult for individuals who depend on them for their way of life. Climate change adaptation issues represent significant social, institutional, environmental and economic challenges. Success stories in this area are the result of multisectoral initiatives, involving players from the public and private sectors and civil society, and their inclusion in existing planning efforts. Acquiring data to monitor the condition of infrastructure and efforts to search for effective solutions for transportation systems are key means of adapting to the inevitable changes. Adaptation options will affect both the design and management practices for the operation and maintenance of infrastructure. Analysing the potential performance of these options depends on a solid knowledge of the transportation systems and the environment in which they operate.
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.
