Ontario operates four publicly funded school systems, with there being both English and French equivalents of the public school system and the Catholic school system. About half of Ontario's government-funded District School Boards are Catholic (37 out of 72). There are some publicly funded schools with non-Catholic religious affiliation: these include
Eden High School (under the
District School Board of Niagara) and the Burkevale Protestant Separate School (under the
Penetanguishene Protestant Separate School Board). Legislation regarding primary and secondary level education in Ontario is outlined in the
Education Act. , two million children were enrolled as students within the province.
Elementary schools teach children enrolled in kindergarten and grades 1–8, while
secondary schools teach adolescents in grades 9–12. Four and five year olds may enter
kindergarten programs but are not required by law to do so until they turn six that calendar year.
Separate school systems In 1867, the
Constitution of Canada outlined protections for educating both Protestant and Catholic students. As a result of legislative developments, only Ontario,
Alberta, and
Saskatchewan continue to keep these
separate school systems; although Ontario is the only province that fully funds such schools. Public debate regarding whether to dissolve Catholic school funding has existed since the 1980s, Catholic individuals can choose whether to direct their property taxes to Catholic or public school boards. In 1996,
Adler v Ontario determined that provinces could choose how to direct their funding to religious schools. In 1999, the
United Nations concluded that Ontario's funding of Catholic schools is a form of
religious discrimination, as other religions do not receive such funding for their schools. Possible solutions presented by the United Nations for remedying the matter were either removing faith-based funded entirely or extending such funding to other religious schools. Non-Catholic teachers cannot apply for an estimated third of total available teaching jobs in the province, as being Catholic is a requirement to work for a Catholic school board. A 2018
Ipsos poll concluded that 60% were in favour of a single school system that was publicly funded. Proponents argue that defunding the Catholic school system would be more fair to people with different religious backgrounds and save an estimated $1.2 to $1.5 billion annually.
Secondary schools High school students typically take four classes in a semester, unless the school has a
multiple subject instructional period (MSIP), where students will take five classes instead. Students are
streamed into either "applied" or "academic" tracks in grade 10. It is difficult for applied track students to switch to academic courses. Black and indigenous students are placed in applied streams more often in comparison to white students. Since streaming directly influences a student's options for postsecondary education, the practice has been criticized for discriminating against minority students. Some schools offer a
Specialist High Skills Major (SHSM) where students can apprentice trades before graduating. An expanded program involving trades apprenticeship is planned for 2025. The
Ontario Secondary School Diploma (OSSD) has various requirements. High school students must complete 30 credits. 12 of these credits are mandatory courses, while the other 18 are
electives chosen by the student. Additional academic requirements include a passing grade on the
Ontario Secondary School Literacy Test and on the financial literacy test. 40 hours of
volunteer service are also a graduation requirement. Individuals that do not graduate may enroll as
12B students, which allows for an extra year of schooling to graduate. 12B students might have already earned their OSSD and use the program for
victory lapping. There is no legal age or time constraint against attending secondary school longer than 4 years, although a limit on course credits exists. Students who graduate with an 80% average earn an
Ontario Scholar certificate. Before the discontinuation of the program in 2024, adult learners who had not earned their Ontario Secondary School Diploma could earn an equivalent certification through
General Education Development (GED). There is no replacement program for GED.
French immersion Some public schools offer a
french immersion program. It is distinct from francophone education, as it is meant to immerse anglophone students in the language. French immersion programs were first introduced in Canada in the 1960s. Students enrolled in french immersion programs in Toronto are typically middle class and white. Entrance into these programs is limited and therefore competitive, as parents want their children to have better employment opportunities. Some schools offer it to parents on a first-come, first-served basis, while others perform a
lottery. The program has been criticized as elitist and contributing to structural inequalities in Canada.
Private schools Under the
Education Act, private schools in Ontario are required to offer the Ontario curriculum or a program not of lesser educational value than it. It must also submit a
notice of intention to legally operate within the province. A private institution is considered a school if "instruction is provided at any time between the hours of 9 a.m. and 4 p.m. on any school day for five or more pupils who are of or over compulsory school age in any of the subjects of the elementary or secondary school courses of study." Private schools that meet provincial standards may offer the Ontario Secondary School Diploma. == Higher education ==
