The Canadian International School (CIS) is an international school in Singapore. CIS operates under the International Baccalaureate (IB) Primary (IB PYP), Middle Years (IB MYP), and Diploma (IB DP) programs. The school accepts students from Nursery to Grade 12.

The school was established in 1989^[1] by a group of Canadian-Chinese investors^[2] and opened in November of 1990^[3] as a university preparatory day school known as the Canadian Overseas College (COC) in response to "the need for a Canadian system of education in the ASEAN region" by expatriates.^[4] The COC campus was located in the former building of the Toh Tuck Primary School at Toh Tuck Road in Bukit Timah. It was fully accredited by the Ontario Ministry of Education as well as offered education from grade 9 to 13 as a part of the Ontario Academic Credit (OAC) system and issued the Ontario Secondary School Diploma (OSSD) to graduating students.^[4] In 1991, the school only had 40 students attending the school out of its capacity of 400 students.^[3] By 1992, there were 300 students attending the school^[5] due to a spillover from Dover Court and United World College, which was caused by an influx of expat students. In September of 1992, it changed its name to the Canadian International School.^[6] Around a month earlier, the school expanded its education to grade 7 and 8.^[7] In March of 1993, it expanded its programme from kindergarten to grade 6.^[8] In September of the same year, the school starting offering Mandarin as a second language, with 15 students signing up for the elective.^[9] It was later made compulsory for primary students in 1994.^[10] In August 2001, CIS opened a new campus in Bukit Tinggi, Bukit Timah, and moved its grade 9-12 students there. Two years later, the grade 7-8 students were moved there, making the Toh Tuck campus a primary student-only campus. However, in August 2006, the grade 4-6 students moved to the Bukit Tinggi campus whilst the grade 9-12 students moved to a new campus in Kampong Bahru as the student population was growing. In 2002, the school was authorised by the International Baccalaureate (IB) to offer the Diploma Programme (DP). A year later, it was authorised to offer the Middle Years Programme (MYP). In May of 2005, it was authorised to offer the Primary Years Programme (PYP).^{[citation needed]}

In 2008, the SLA approved CIS' plans to reuse the former Tanjong Katong Girls' Secondary School campus at Tanjong Katong Road as a part of its Tanjong Katong Campus.^[11] When CIS took over the building, the school hall had " broken windows and a big hole in the roof... the requirement was to restore the hall to its original look and state" according to Angela Henderson, the school's principal. The damages were subsequently fixed and the school hall was refurbished with new flooring and a fresh coat of paint for the stage.^[12] The Tanjong Katong Campus closed in June 2023, and students transferred to the Lakeside campus in August 2023.

On March 21 2012, the Lakeside Campus of CIS was opened by then Education Minister S. Iswaran. Talks were made with other schools on sharing playing spaces.^[13] In January 2023, CIS opened the Toh Tuck Wing, a Kindergarten wing and sporting facility.^[14][15]
