Canadian cities are facing escalating costs due to the impacts of climate change, with billions of dollars being spent on repairing infrastructure damaged by extreme weather events. A recent analysis suggests that a shift towards proactive climate-proofing of public infrastructure could save the country significant sums each year.
Reports indicate that without adaptation measures, Canada could face average annual infrastructure costs of approximately $15.1 billion over the next 75 years. However, investing around $4.1 billion annually in climate-resilient infrastructure could reduce these costs to $2.5 billion per year. This proactive approach could lead to annual savings of up to $8.6 billion. Roads, bridges, and water systems are particularly vulnerable, with decades of deferred maintenance exacerbating their susceptibility to damage from rising heat and heavy rainfall.
Experts like Ryan Ness from the Canadian Climate Institute emphasize that the current infrastructure was not designed for the increasing frequency and intensity of extreme temperatures. This leads to issues such as buckling roads and degrading bridges, requiring more frequent and costly repairs. Beyond physical infrastructure, experts also call for changes in community policies and bylaws to better support residents during extreme weather, such as establishing maximum indoor temperatures for homes.
The Federation of Canadian Municipalities and the Insurance Bureau of Canada have also highlighted the substantial financial burden on municipalities, estimating annual adaptation costs at $5.3 billion. They advocate for long-term investment plans and exploring innovative ways to engage private sector capital to enhance community resilience. This call for action underscores the urgent need for a strategic, forward-looking approach to mitigate the financial and social impacts of climate change across Canada.
