Canada East () was the northeastern portion of the United Province of Canada. Lord Durham's Report investigating the causes of the Upper and Lower Canada Rebellions recommended merging those two colonies. The new colony, known as the Province of Canada, was created by the Act of Union 1840 passed by the Parliament of the United Kingdom, having effect in 1841. For administrative purposes, the new Province was subdivided into Canada West and Canada East. The former name of "Lower Canada" came back into official use in 1849, and as of the Canadian Confederation of 1867, it formed the newly created province of Quebec.
