ISNS was founded in 2002 through the cooperation of the Government of Canada, the Province of New Brunswick and Dr. Francis Pang to fulfil a local need for international education.

The campus includes a large gymnasium, full outdoor track and field, playground, table-tennis, basketball, and volleyball courts.

Canadian officials support and review the educational programs and teaching methodologies.

Students also write Provincial assessments (Province of New Brunswick, Canada) to ensure curriculum consistency.

As well as being linked with the Canadian Province of New Brunswick's Department of Education, ISNS is also affiliated with UNESCO, and ACAMIS (Association of China and Mongolia International Schools).
