Bridges allow people to commute faster, shorten distances and create wealth. There are more than 47 thousand public-owned bridges in Canada, 43.9% of which were on local roads, 24.6% on highways and expressways, and 26.0% on arterial and collector roads combined. Footbridges accounted for 5.5% of all bridges.
Tunnels are as relevant as bridges. They make commuting faster and shorten distances. However, tunnels are much more complex to build. Tunnels are also an important piece in the resource industry. Canada is a large resource exploration country, especially in the mining sector, for which tunnels are at the top of the infrastructure that enables that exploration.
There are over 15,000 dams in Canada, of which 1,157 are categorized as “large” dams under the ICOLD definition. The great majority of large dams in Canada were built as components of large hydroelectric projects. Canada is the world’s second-biggest producer of hydropower, generating 380 TWh/year (2019). That output represents 59.3 percent of the country’s total electricity production. Canada has developed world-renowned expertise in hydropower and dam projects design, construction and management.
