     NOTES

†Prior to 2010, Petit-Mécatina belonged to Minganie Regional County Municipality which was given explicit EST/EDT status under the 2006 time act. Given that Petit-Mécatina is no longer part of Minganie, and given that it is entirely east of 63°W, a careful interpretation of 2006 time act will place Petit-Mécatina on permanent Atlantic Standard Time (AST) from 2010 onwards. This may be considered moot because Petit-Mécatina is a vast wilderness with no infrastructure and no inhabitants.
