The Great Migration of Canada (also known as the Great Migration from Britain) was a period of high immigration to Canada from 1815 to 1850, involving over 800,000 immigrants. Though Europe was becoming richer through the Industrial Revolution, population growth made the relative number of jobs low, forcing many to look to the New World for economic success, especially Canada and America.
In the late 18th and early 19th century, there occurred a transition in parts of Great Britain's previously manual-labour-based economy towards machine-based manufacturing. It started with the mechanization of the textile industries, the development of iron-making techniques and the increased use of refined coal. Though the Revolution began an era of expanded economic growth and higher standards of living, it was at the same time met with a rapid population explosion. A slow rise in quality of living standards throughout the past two hundred years allowed more children to survive and made child bearing more economic. As well, jobs that were previously done by poor peasants could now be done even more cheaply by machinery. This led to the loss of many jobs. The combined effects made it difficult for some to find jobs, leading them to look to the colonies in the Americas for work.
Because the Industrial Revolution began in Britain, the first (and therefore the majority of) settlers were English-speaking British. Sixty percent of these immigrants to Canada were British. This made them the largest group in Canada. The Irish came to escape the Great Potato Famine.
Other people from other countries migrated as well. Americans went to British Columbia in order to look for gold, a material that was quickly evaporating because of the California gold rush. Chinese went to British Columbia too in order to help build the Canadian Pacific Railway, and to escape war and famine in their own country. These migrations can be considered apart from those in earlier times.
