Technological and industrial history of Canada

The technological and industrial history of Canada encompases the country's development in the areas of transportation, communication, energy, materials, public works, public services (health care), domestic/consumer and defense technologies. Most technologies diffused in Canada came from other places. Only a small number actually originated in Canada. For more about those with a Canadian origin see Invention in Canada.

The terms chosen for the "age" described below are both literal and metaphorical. They describe the technology that dominated the period of time in question but are also representative of a large number of other technologies introduced during the same period. Also of note is the fact that the period of diffusion of a technology can begin modestly and can extend well beyond the "age" of its introduction. To maintain continuity, the treatment of its diffusion is dealt with in the context of its dominant "age". For example the "Steam Age" here is defined as being from 1840 to 1880. However steam powered boats were introduced in 1809, the CPR was completed in 1885 and railway construction in Canada continued well into the twentieth century. To preserve continuity, the development of steam, in the early and later years, is therefore considered within the "Steam Age".
