Prince Edward Island
From RationalWiki
Prince Edward Island is Canada's smallest province, both in terms of size and population. It is given-over mainly to potato farming. It is also the only province which is entirely off of the mainland.
PEI is primarily notable because Stompin' Tom Connors wrote a song about it. And honestly, that's plenty.
