They were redistributed whenever a readjustment took place at the federal level. In 2005, legislation was passed by the Legislature to divide Ontario into 107 electoral districts, beginning with the next provincial election in 2007. The eleven northern electoral districts, including Thunder Bay—Atikokan, are those defined for federal purposes in 1996, based on the 1991 census (except for a minor boundary adjustment).

Without this legislation, the number of electoral districts in northern Ontario would have been reduced from eleven to ten.Elections Ontario web site, “New Electoral Boundaries”
