Aging infrastructure refers to public facilities, utilities, and structures that have reached or exceeded their expected lifespan and need major repair or replacement. This includes water and sewer pipes (some over 100 years old), roads, bridges, public buildings, and transit systems. Much of Canada's infrastructure was built in the 1950s-70s and is now deteriorating. The 'infrastructure deficit'—the gap between what needs to be spent on repairs/replacement and what's actually being spent—is estimated at hundreds of billions of dollars nationally. Addressing aging infrastructure is expensive, and municipalities often struggle because property taxes alone can't fund the massive investments required. This is why infrastructure funding from federal and provincial governments is so important.
