John Polanyi Collegiate Institute (JPCI), formerly Bathurst Heights is a public high school in Toronto, Ontario, Canada. It is housed in the former Bathurst Heights Secondary School building. It is located in the North York district, near Lawrence Avenue West and Allen Road in the area of Lawrence Heights. Prior to 1998, the school was part of the North York Board of Education.

It is a semestered school offering a "full range of university, college and apprenticeship programs."

Bathurst Heights was opened in 1952 and later closed in 2001. Upon its closure, students were transferred to Sir Sandford Fleming Secondary School. Sir Sandford Fleming Secondary School was constructed and opened in September 1964. Fleming's school was created with the same design as Newtonbrook Secondary School. Fleming's teams were known as the Chargers. On September 6, 2011, Fleming was closed with the Fleming staff and students moving into the former Bathurst Heights Secondary School on Lawrence and Allen. Bathurst, in turn, was renamed John Polanyi Collegiate Institute . The name of the school team was changed to the Jaguars with their colours being blue and black.

Bathurst Heights Secondary School opened on September 4, 1951, as North York's second high school (the first being Earl Haig Secondary School) and officially opened on May 29, 1952. Six additions were made throughout the years and adult education was introduced before its program being abolished in 2000. After years of declining enrollment, Bathurst Heights closed its doors as a regular operating school on June 23, 2001. The sports teams were known as the Bathurst Bears with team colours being green and white. The school was well equipped with a cafeteria, a separate theatrical auditorium, swimming pool, wood shop, metal shop, auto body shop and an auto mechanic shop. To help prepare students for University, the school had a lecture hall, named in memory of John F. Kennedy (Kennedy Hall).

In 2004 the school was used in the filming of the Zero Hour episode: Massacre at Columbine High.

In the 2000s, the Toronto Catholic District School Board used the Bathurst Heights building to house the students from Brebeuf College School during re-construction and later Dante Alighieri Academy Beatrice Campus.
