The Dionne quintuplets (French pronunciation: [djn]; born May 28, 1934) are the first quintuplets known to have survived their infancy. The identical girls were born just outside Callander, Ontario, near the village of Corbeil. All five survived to adulthood.The Dionne girls were premature. After four months with their family, custody was signed over to the Red Cross who paid for their care and oversaw the building of a hospital for the sisters. Less than a year after this agreement was signed, the Ontario government stepped in and passed the Dionne Quintuplets' Guardianship Act, 1935 which made them wards of the Crown until the age of 18. The Ontario provincial government and those around them began to profit by making them a significant tourist attraction.

The identical quintuplet girls were, in order of birth:

Yvonne douilda Marie Dionne (died 2001)

Annette Lillianne Marie Allard (living)

Ccile Marie milda Langlois (living)

milie Marie Jeanne Dionne (died 1954)

Marie Reine Alma Houle (died 1970)

The Municipality of Callander (formerly the Township of North Himsworth) 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."
