The Interior Plains is a vast region of North America that stretches from Canada's western arctic region all the way down to the border of Mexico. The Great Plains is a term used mainly in the US, referring to a large section of the Interior Plains, west of the Mississippi. The term includes Canadian territory, but is rarely used in Canada. In Canada it is more common to refer to the entire Interior Plains as one unit, or to use the term prairie. Alberta, Saskatchewan and Manitoba are commonly called the Prairie Provinces.
