In 2007, the average age of Canada's public infrastructure reached 16.3 years, down from its peak of 17.5 in 2000.
A reduction in the average age is indicative of a general trend toward a younger stock of investments. It doesn't necessarily imply that each physical asset is younger or in better condition, or that a greater proportion of assets meets specific quality standards.
Ontario had the youngest public infrastructure system in the country in 2007, followed closely by Prince Edward Island and Alberta. Nova Scotia had the oldest, followed by Manitoba and Saskatchewan.
The average age of the five public infrastructure assets was higher than the national average in all provinces east of Ontario in 2007. The single exception was Prince Edward Island, where infrastructure on average was a relatively young 15.5 years, thanks to the Confederation Bridge. Average age in British Columbia was equal to the national average.
In Quebec, all five infrastructures were still older than the national average in 2007, even though investment in highways and roads has been strong since 2001.
