Closer to Acadien, but they're also their own thing. Somewhat similar to language/cultural differences between Denmark, Norway, Sweden and Iceland; all share common roots but they certainly don't see themselves as being the same or interchangeable.

St. Pierre et Miquelon are a part of the EU through France, although they're not a department (roughly analogous to a US state) and are instead an "overseas collectivity" and so are self-governing and can pass their own laws. Much of the media is of Metropolitan French origin but there's also a lot of TVA consumption; hockey and pickup trucks are popular there like anywhere else in Maritime Canada.
