Prince Edward Island (or PEI) is one of the Atlantic Provinces of Canada. It is Canada's only island province. It is the smallest province by both area and population, but is also the most densely populated province. "The Island", as locals call it, is well known for its beautiful sandy beaches and dunes. It is also the home of the gregarious Anne Shirley from Lucy Maud Montgomery's classic Anne of Green Gables. It became the "Cradle of Confederation" after the Fathers of Confederation met there in 1864 to discuss the possible union of five British North American colonies. Canada was formed three years later in 1867.
