Song for the Mira and other songs by the Cape Breton songwriter Allister MacGillivray for sheer love of place.

For just plain silly: "Mermaid of Ontario" by Shel Silverstein & Pat Dailey A favorite around Lake Erie - has been recorded by Lee Murdock - whose exploration of Great Lakes songs isn't limited to the American Side - many of his (serious) songs have Canadian context and place names.

David Mallet's Ballad of St. Anne's Reel mentions Prince Edward Island
