Canada East

Canada East (French: Canada-Est) was the northern-eastern portion of the United Province of Canada.Lord Durham's Report investigating the causes of the Upper and Lower Canada Rebellions recommended merging the two Canadas. The new provincial colony was created by the Act of Union 1840 passed by the Parliament of the United Kingdom, having effect in 1841. It continued to exist as part of the Province of Canada until Canadian confederation in 1867. An estimated 890,000 people lived in Canada East in 1851.

It consisted of the southern portion of the modern-day Canadian province of Quebec. Formerly a British colony called the Province of Lower Canada, based on Lord Durham's report it was merged with the Province of Upper Canada (present-day southern portion of the Province of Ontario) to create the United Province of Canada.

It was primarily a French-speaking region.

Due to heavy immigration, the population of English-speaking residents of Canada West soon outstripped Canada East. Under the Act of Union 1840 the seats in the lower legislature were evenly divided between East and West. There was no provision under the Act for representation by population.
