Preparing Infrastructure for Tomorrow’s Climate A Call to Action

As the spectre of climate change looms larger, Canada finds itself grappling with unprecedented challenges that demand a proactive and strategic response.

Spring, once a season of renewal and lightness, now serves as a harbinger of anxiety, signalling the onset of extreme weather events such as floods, wildfires, and heatwaves. These events, exacerbated by climate change, are reshaping Canada’s landscape and infrastructure, underscoring the urgent need for adaptation and resilience measures. Last year witnessed an unprecedented onslaught of wildfires across the country, accompanied by smoke that engulfed entire continents. In previous years, Canada experienced the intensity of Hurricane Fiona, leaving a trail of destruction along its East Coast. Now, as Canadians brace for the uncertainties of spring and summer 2024, the impacts of a strong El Niño and the looming threat of drought and wildfires loom large on the horizon. The economic toll of climate change is staggering, with estimates suggesting that key impacts are already costing Canadian households approximately $720 annually. By 2050, the cumulative economic burden could soar to a staggering $78 to $101 billion per year. These impacts reverberate across all regions, with infrastructure bearing the brunt of climate-driven disasters.

From the deluge in Nova Scotia to the catastrophic floods in British Columbia, Canada’s infrastructure faces unprecedented challenges. The damage inflicted by extreme weather events underscores the urgent need for resilient infrastructure that can withstand the onslaught of climate change. Governments at all levels must adopt a proactive approach to infrastructure planning and development. This entails updating codes and standards to incorporate climate resilience, investing in robust flood mapping systems, and allocating resources to build infrastructure that can weather future climate extremes.

While the upfront costs of adaptation may seem daunting, research indicates that every dollar invested in climate resilience yields significant returns in future savings. Positive strides are already being made, with examples such as the reconstruction of bridges along B.C.’s Coquihalla highway and infrastructure upgrades in St. John’s, New Brunswick, showcasing the potential for resilience-building measures. However, concerted and coordinated efforts are needed to prepare Canada’s infrastructure for the challenges of tomorrow. Without decisive action, the increasing impacts of climate change will exact a heavy toll on governments, communities, and economies. The time to act is now, to ensure that Canada’s infrastructure is not only resilient but also capable of supporting a sustainable and prosperous future.
