This report introduces the Costing Climate Change Impacts on Public Infrastructure project, which provides projections of the long-term costs that certain climate change hazards will impose on Ontario’s provincial and municipal infrastructure budgets. The report outlines the context and methodology, describes the climate hazards included in the project, and discusses the projections of these hazards to public infrastructure. Results will be published in three sector reports for buildings, transportation, and water infrastructure.
This report estimates the impacts of changes in extreme rainfall, extreme heat and freeze-thaw cycles on the long-term costs of maintaining public buildings in a state of good repair. The report shows that these climate hazards will materially increase the cost of maintaining public buildings in Ontario, and the future severity of climate change will have a direct impact on provincial and municipal infrastructure budgets.
