The Municipality of Callander is a township in central Ontario, Canada, located at the southeast end of Lake Nipissing in the Almaguin Highlands region of the District of Parry Sound. The municipality is located on Callander Bay, just south of North Bay. The municipality renamed itself from North Himsworth to Callander in 2003, adopting the name of its major community because, in the words of then-mayor Bill Brazeau, "Nobody knew where North Himsworth was."
