St. Andrew's College (SAC) is an independent boarding and day school founded in 1899 and located in Aurora, Ontario, Canada. It is a university-preparatory school for boys in grades 5 to 12, with a focus on academic achievement, athletics, and leadership development. It is accredited by the Canadian Educational Standards Institute and is affiliated with other associations, including CAIS, CASE, NAIS and the International Boys' Schools Coalition (IBSC). The school's coat of arms was registered with the Canadian Heraldic Authority on August 15, 2006.

St. Andrew's College was first situated at the northeast corner of Yonge Street and Roxborough Avenue in the Toronto neighbourhood of Rosedale, in a house named Chestnut Park that was previously owned by Sir David Macpherson. The college opened on September 10, 1899 under the direction of Headmaster Rev. George Bruce and the first student to enroll was Douglas W. Fraser ('06). By the end of the first school year there were 56 students, 13 being boarders.

Rev. Bruce was succeeded by D. Bruce Macdonald as Headmaster in 1900, and in 1901 the school published its first yearbook: The Review. The Old Boys Association, still active presently, was founded in 1903.

In 1905, due to the increasing size of the student body, the school moved to a new campus within Rosedale, west of MacLennan Avenue, from Summerhill Avenue to Douglas Drive just north of Rosedale Field, in a large Collegiate Gothic structure. The Rosedale Campus was designed to serve 150 boarders, 300 day boys, and 9 masters.

By 1909, the college had students from Canada, Jamaica, the United States, Mexico, Costa Rica, Panama, China, and Bermuda. In 1911, the college became a corporation under the control of a Board of Governors.

Over 600 Old Boys fought in the First World War, and 104 lost their lives along with 2 masters. From 1918 to 1920, the college temporarily moved to Knox College, as the Rosedale Campus served as a military hospital for wounded soldiers from the First World War.

The school made its final move in 1926 to Aurora, where the current campus occupies a 126-acre (0.51 km) site in a suburban environment. Its Georgian Revival architecture is built around the traditional quadrangle form. The Memorial Gateway entrance was completed in 1928.

Over 600 Old Boys served during the Second World War with 45 losing their lives, plaques listing their names are displayed within the memorial chapel.

1956, the school newsletter The Andrean was created and has been published since.

There are four boarding houses on campus, which is home to approximately half of the 651 boys. Many members of the faculty also live on-campus.

The Aurora campus was featured in the filming of Cadet Kelly and the 5th episode of the Netflix mini-series The Queen's Gambit.

St. Andrew's is also home to Canada's second largest Royal Canadian Army Cadets Corps. Established in 1905, the #142 St. Andrew's College Highland Cadet Corps is now a multi-year leadership program, but still culminates in an annual inspection and parade in May. The cadet program focuses on developing leadership and teamwork skills in the boys.

The cadet corps was raised in the fall of 1905 under the direction of schoolteacher Grant Cooper, following the model of military training offered at Upper Canada College and Trinity College School. 70 boys initially joined the corps as only a limited number of uniforms were available. The first Cadet Inspection was held at the Rosedale Campus on May 14, 1906, under the Command of Captain Cooper, and the first student cadet commander was First Lieutenant Vincent Massey. On April 24, 1906, the corps made its first public appearance at Queen's Park where it was reviewed by the Duke of Connaught, and on May 18 it participated in training drills with the 48th Highlanders. The cadet corps provided a guard of honour during the Royal Tour of 1939.

The School's cadet corps is affiliated with the 48th Highlanders of Canada and retains the same motto ("Dileas Gu Brath" – "Faithful Forever") as well as uniform (scarlet tunic and Modern Gordon tartan). In 2005, the centennial year, the Corps was granted the Freedom of the City of Aurora.

The Pipes and Drums Band is an integral part of the St. Andrew's College Highland Cadet Corps and one of its best-known elements. The Pipes and Drums were established in 1915 under the tutelage of Pipe Major James Fraser of the 48th Highlanders, formerly of the Gordon Highlanders who had fought at Dargai and in South Africa. In 1941, a jaguar skin that had been shot by Theodore Roosevelt was donated to the college to be worn by the bass drummer.

The primary responsibility of the Pipes and Drums Band is to provide music for the Battalion when it is on the march. In this role, the Band will be front and centre at the Annual Church Parade, the Headmaster's Parade, and the Annual Inspection in May.

Internationally renowned as "North America's piping heartland" for its Piping and Drumming program, St. Andrew's College attracts hundreds of potential pipers each year to its summer "Ontario School of Piping and Drumming at St. Andrew's College" camp. In June 2019, the decision was made to field a competitive band in grade 3 alongside the existing band, which competed in grade 5.

Each year, St. Andrew's hosts' certain events that are special only to the School. Some of these activities and events involve the School's entire student body, while others invite alumni and their friends and families. These events serve different purposes, some of which are integral to the School's identity while others are used for fundraising causes.

• Annual Cadet Inspection – the annual Cadet Inspection is mandatory for the entire student body at St. Andrew's. The Inspection is usually held in May and invites prominent representatives from all across Canada to inspect the School's Cadet Corps. A tradition that finds its root since 1906, the annual inspection is integral to the School's identity and preserving both the School's Scottish background, and the history of the Cadet Corps.
• An Andrean Christmas – The annual Andrean Christmas is held at Roy Thompson Hall in December and showcases the School's musicians and singers. The Hall holds over 2,000 people and is generally filled to capacity. Like the annual Cadet Inspection, the Andrean Christmas is mandatory and everybody from the student body must attend. Traditionally, Old Boys will return to attend the performance and join in the singing of Amazing Grace. It replaces the tradition of an annual Carol Service in the holiday season.
• Focus Festival of the Arts – This program is a three-day festival of plays, a film festival, visual arts, music and social events for students, parents and guests. Boys who have never been involved in drama or on the stage before are encouraged to participate by writing their own plays, directing, producing or acting in performances large and small.
• Annual Fall Play – An annual Broadway-level play put on for parents, students, and staff during the month of November in the Wirth Theatre. Generally a Musical.
• Celtic Concert – This musical concert showcases the School's Pipes and Drums and feature many school bands, plus outstanding soloists, percussionists and dancers. It highlights traditional Celtic music, military band music, and some show tunes.
• Homecoming – an annual gathering of all St. Andrew's alumni to return to St. Andrew's in September. Held in conjunction with the 5, 10, 15, 20, 25, 30, 35, 40, 45 reunion dinners, this annual gathering is for the entire Andrean community. The Homecoming celebration includes games for the children in the Quad and in the Great Hall, and various sports competitions, culminating in the annual 1st Football match against rivals UCC, Yuill Turf Field. For Upper School students, the Homecoming event usually includes the annual Homecoming dance on Saturday evening.
• MacPherson Tournament – an annual hockey event where the St. Andrew's varsity hockey team competes with hockey teams from other top schools for the MacPherson Cup. The cup is named after three Andreans: Lloyd MacPherson, Jim Hamilton and Bob Meagher, all of whom loved hockey with passion and contributed greatly to the St. Andrew's hockey team. The tournament has a North American flavour, hosting schools from Saskatchewan, New Brunswick, New Hampshire, Massachusetts, Quebec, Indiana, Pennsylvania, Ohio, Florida, New York, Nova Scotia and Michigan as well as a variety of regions in Ontario.
• Prize Day – Prize Day is the culmination of the School's academic year, and features many awards and prizes earned by the School's students. There are two ceremonies, one for the Middle School and one for the Upper School. Prize Day takes place after exams, which are usually completed by early June.
• St. Andrew's Luncheon – every November, a traditional St. Andrew's Luncheon is held, complete with Haggis. All students must attend, wearing their kilts for this special occasion. Like the annual Cadet Inspection, the St. Andrew's Luncheon has taken place since the inception of the School and is integral to the preservation of the School's Scottish traditions.
• Spring Smash – every May, the senior business classes organize a carnival of sorts, where both Middle School and Upper School students are provided a variety of fun activities such as water slides, bouncy castles, a dunk tank for dunking teachers in, and much more. There are also mandatory sports tournaments for house points, and students are given a choice between ball hockey, basketball, soccer, among others. Upper School participates in sports prior to an outdoor BBQ and then the carnival, whereas the Middle School participates in the carnival before their outdoor BBQ and sports.

St. Andrew's College is divided into the Middle School (grades 5–8), and the Upper School (grades 9–12). More than half the students from over 29 countries attending St. Andrew's College live in boarding. Upper School day boys from York Region and the surrounding area, are a part of the four day houses: Ramsey, Laidlaw, Smith or Perrier. Macdonald House is the home to all grade 5–9 boarders, and some select grade 11's who are designated house captains and act as 'big brothers'. Macdonald House is named after the MacDonald family (J. K. MacDonald and J. K. MacDonald II both served as Board Chair and Bruce MacDonald was Headmaster).

The remaining Upper School boarders live in the remaining 3 boarding houses:

• Memorial House — named after the soldiers who died during World War I and World War II.

In 1999 the architectural firm KPMB headed a project which consisted of planning for a new middle school and parking lot on the established campus. From 2000 to 2003, the same architectural firm had an additional project which included the addition of a middle school wing onto an existing building, a parking lot and outdoor spaces and alterations to the existing college, originally constructed in 1926.

In late 2019, The Dalton Company executed a project which saw the complete internal-reconstruction of all 3 floors within the McLaughlin Hall science building. Covering a total area around 26,000 sq ft of space. The original facility was constructed in 1970, also by The Dalton Company and they were invited back 50 years later to renovate the building. Within the CAD $10 million project, the entire interior of the building was reduced back to the core structure, and introduced state of the art facilities for science and technology, university level labs for chemistry and biology, as well as a two-story maker space and robotics/computer science classrooms. The newly renovated McLaughlin Hall also houses a Foucault Pendulum on display which spans vertically through all 3 stories of the building. The pendulum was originally added in 1971 as it was donated following the death of a young student and was re-fitted to the new building.

The La Brier Family Arena is a multi-purpose hockey arena which also houses fitness facilities located on the St. Andrews College campus. It began construction in 2013 after a CAD $5 million donation from the La Brier Family of which it is named after. It was completed in 2014 and was officially opened on September 20, 2014, and will go on to serve as the home base for the school's hockey team, the Saints.

Coulter Hall – A three-floor classroom building opened in 1962—the second and third floor is designated for use by the Math and English departments, respectively.

McLaughlin Hall – A three-story wing connecting the Bedard Athletic Centre, Coulter Hall, and Rogers Hall, originally opened in 1971, it underwent a massive renovation between 2019 and 2021 and serves as the science building featuring state of the art, university level facilities for chemistry, physics, biology, with a 2 story maker space and computer science classes.

The Center for Leadership, Innovation, and Performance (CLIP) – A fairly new 3-level addition to the campus (2015), which is home to the Business, Geography, Drama, and Music classrooms. The main music classroom/band room is the rehearsal space for the School's Wind Ensemble, Symphonic Band, and Jazz Band, along with the Upper School music classes. All of the school plays are held in the Wirth Theatre, which is modelled after Stratford's Festival Theatre. The Reininger Rehearsal space is situated under the Wirth Theatre, and is where the drama classes are held in addition to playing a supporting role for the School's Fall Play, and being used as a performance venue during the FOCUS Festival of the Arts.

The donation was made by Sir Joseph Flavelle, who also donated funds to establish Flavelle House. Morning services and special services such as the Remembrance Day Service are held in the Memorial Chapel.

Dunlap Hall – This is one of the original four buildings on campus. Today it houses the School's administrative facility. Dunlap Hall is separated into two floors: the first serves numerous functions including the Headmaster's office, admission office, administration office, and university counselling. It is also serves as a connection to the library. The second floor houses the alumni and advancement office and the business office. In the basement are the day boy lockers as well as a multi-faith prayer room.

Staunton Gallery – A now-converted outdoor courtyard, it is a main part of the School where many students congregate, and was dedicated to departing Headmaster Ted Staunton. It has connections to the Wirth Art Gallery, Dunlap Hall, Ketchum Auditorium, Coulter Hall, CLIP, McLaughlin Hall, and Rogers Hall.
