Infrastructure encompasses the foundational physical systems and facilities that enable a community to function: transportation networks (roads, bridges, transit systems), water systems (treatment plants, distribution pipes, reservoirs), wastewater systems (sewers, treatment facilities), stormwater management, electricity and communications networks, and public buildings. Infrastructure also increasingly includes "soft" infrastructure like social service facilities and green infrastructure like parks and natural systems. Municipal infrastructure represents enormous asset value—typically the largest investment a community has made over its history. Infrastructure enables economic activity, protects public health, and shapes quality of life. Canada faces a significant infrastructure deficit—decades of deferred maintenance and renewal have created backlogs requiring major investment. Infrastructure decisions have long-term implications: facilities built today will serve communities for 50-100+ years, and choices about location and capacity shape development patterns for generations.
