Ontario's industrial and transportation heritage can be traced back to the first mills and dams built
along major waterways in the eighteenth century. From waterpower to steam engines to hydroelectricity,
industry powered the Upper Canadian economy in tandem with agriculture and it supported the settlement and
growth of communities, villages, towns and cities. Transportation networks soon followed, expanding with the
exportation of goods and the importation of immigrants. Aboriginal pathways evolved into rutted, muddy roads,
improved over time, and land patents required new settlers to clear the surveyed right of way adjacent to
their holdings. New forms of transportation such as railways in the nineteenth-century and automobiles in the
twentieth further transformed the landscape with increasingly intricate social, economic and communication
networks.

Canada's industrial and transportation heritage can be seen in the built environment and uncovered below
ground in historic archaeological deposits. The need for historic research and evaluation of industrial and
transportation heritage sites has grown steadily in Ontario as individuals in the public and private sector
consider adaptive reuses of older properties as well as the replacement of an aging transportation
infrastructure. Adaptive re-use offers up many possibilities for the developer while heritage conservation
offers new life to significant historic properties whose original functions and forms may be obsolete.
