What age does a child start school in Canada depends on the province. Most Canadian children start kindergarten the September after they turn five, and Grade 1 the September after they turn six, but the legal compulsory age is six in most provinces, five in British Columbia and three Atlantic provinces, and seven in Manitoba and Saskatchewan. This guide gives you the per-province numbers, the kindergarten cutoff dates, and a clean grade-by-age chart so newcomer families can place a child correctly on day one.
Quick Answers (TL;DR)
- Most common kindergarten start age: 5 years old, the September after the child turns 5.
- Most common Grade 1 start age: 6 years old, the September after the child turns 6.
- Compulsory school age: 6 in most provinces, 5 in British Columbia, New Brunswick, Nova Scotia, and Yukon, and 7 in Manitoba and Saskatchewan.
- Mandatory until: Age 16 in most provinces; age 18 in Manitoba, New Brunswick, and Ontario or until a high school diploma is earned.
- Cutoff date for kindergarten enrollment: December 31 in every province and territory except Quebec, which uses September 30.
- Two-year kindergarten provinces (JK + SK): Ontario, Nova Scotia, the Northwest Territories, and Quebec (under the maternelle 4 ans rollout).
- Quebec is different. Secondary school ends one year earlier (Sec V at age 16 to 17), and post-secondary begins with two years of CEGEP before university.
When Do Kids Start School in Canada? The Short Answer
The Canadian school year starts in early September. A child starts school in the September of the calendar year in which they reach the entry age set by their province. In nine provinces, that calendar year is fixed by the December 31 cutoff: a child who turns five at any point during the year (January 1 to December 31) starts kindergarten that September. Quebec is the outlier, using a September 30 cutoff, so a child born in October who would start kindergarten in Toronto must wait an extra year in Montreal.
Education in Canada is run by the provinces and territories under section 93 of the Constitution Act, 1867. There is no national ministry of education and no national school starting age. The federal Department of Indigenous Services Canada administers schools on First Nations reserves. Every other school comes under the provincial education statute, which is why the answer to what age does a child start school in Canada changes the moment you cross a provincial line.

Compulsory School Age by Province and Territory
The compulsory school age is the age at which a child must legally be enrolled in school, either at a public school, a registered private school, or a registered home-school program. The table below summarizes the rules in effect for the 2026 to 2027 school year.
| Province / Territory | Must Start School At | Must Stay In School Until | Statute |
|---|---|---|---|
| Alberta | 6 | 16 | School Act, RSA 2000 |
| British Columbia | 5 | 16 | School Act, RSBC 1996 |
| Manitoba | 7 | 18 (or graduation) | Public Schools Act |
| New Brunswick | 5 | 18 (or graduation) | Education Act |
| Newfoundland and Labrador | 6 | 16 | Schools Act, 1997 |
| Nova Scotia | 5 | 16 | Education Act |
| Ontario | 6 | 18 (or graduation) | Education Act, RSO 1990 |
| Prince Edward Island | 5 | 16 | Education Act |
| Quebec | 6 | 16 | Education Act, RSQ |
| Saskatchewan | 7 | 16 | Education Act, 1995 |
| Northwest Territories | 5 | 16 | Education Act |
| Nunavut | 5 | 16 | Education Act |
| Yukon | 5 | 16 | Education Act |
Two things to note. First, even in provinces where the legal start age is 6 or 7, kindergarten is offered (and almost universally taken up) at age 4 or 5. The legal age is the floor, not the norm. Second, provinces that allow attendance until 18 do not force a teenager to remain in school past 16 if they have already earned their diploma; the rule is “until 18 or graduation,” whichever comes first.
Kindergarten Age in Canada by Province
Kindergarten in Canada usually means the year before Grade 1, but four jurisdictions run a two-year kindergarten program (junior kindergarten followed by senior kindergarten). The cutoff date is what determines whether a particular child starts this September or next.
| Province / Territory | Kindergarten Start Age | Two-Year Program? | Cutoff Date |
|---|---|---|---|
| Alberta | 5 (turning 5 by Dec 31) | No | December 31 |
| British Columbia | 5 (turning 5 by Dec 31) | No | December 31 |
| Manitoba | 5 (turning 5 by Dec 31) | No | December 31 |
| New Brunswick | 5 (turning 5 by Dec 31) | No | December 31 |
| Newfoundland and Labrador | 5 (turning 5 by Dec 31) | No | December 31 |
| Nova Scotia (“Grade Primary”) | 5 (turning 5 by Dec 31) | No (single Primary year) | December 31 |
| Ontario (JK + SK) | 4 (turning 4 by Dec 31) | Yes | December 31 |
| Prince Edward Island | 5 (turning 5 by Dec 31) | No | December 31 |
| Quebec (maternelle) | 5 (turning 5 by Sep 30) | Yes (4 ans + 5 ans, rollout in progress) | September 30 |
| Saskatchewan | 5 (turning 5 by Dec 31) | No | December 31 |
| Northwest Territories | 4 (turning 4 by Dec 31) | Yes | December 31 |
| Nunavut | 5 (turning 5 by Dec 31) | No | December 31 |
| Yukon | 5 (turning 5 by Dec 31) | No | December 31 |
Two of the most useful facts for newcomer families sit inside this table. Ontario and the Northwest Territories run a full two-year kindergarten program (junior kindergarten at age 4, senior kindergarten at age 5) and both are free in the public system. Nova Scotia uses the term “Grade Primary” instead of kindergarten, but it is the same year (age 5) under a different name. Quebec has been rolling out a province-wide maternelle 4 ans (4-year-old kindergarten) since 2017, and as of the 2026 to 2027 school year it is offered in most public school boards through the ministère de l’Éducation.
Is Kindergarten Mandatory in Canada?
Kindergarten is mandatory in only a handful of jurisdictions. In New Brunswick, Nova Scotia, Prince Edward Island, the Northwest Territories, Nunavut, and Yukon, the compulsory school age is 5, which means kindergarten or Grade Primary is part of the legal requirement. In British Columbia, kindergarten attendance for 5-year-olds is also part of the legal compulsory-age rule.
In Alberta, Newfoundland and Labrador, Ontario, Quebec, and Saskatchewan, kindergarten is offered but optional. Parents can keep a 4 or 5-year-old at home and start their child in Grade 1 at age 6 (age 7 in Saskatchewan) without breaking any law. In practice the vast majority of Canadian families do enroll their child in kindergarten, because Grade 1 teachers structure the curriculum on the assumption that students arrive with a year of kindergarten behind them.
In Manitoba and Saskatchewan, the compulsory age is 7, which is the highest in Canada. A child can legally start formal schooling in Grade 1 in those provinces, although both school systems make kindergarten freely available at age 5 and most families take it.
Canadian School Grades by Age
This is the chart most newcomer families need when they walk into a school board office for the first time. It is the standard placement reference for English-language public schools in nine provinces and the territories. Quebec uses a different secondary-school structure and is shown separately below.
| Grade Level | Typical Age (September) | Stage |
|---|---|---|
| Junior Kindergarten (JK) | 4 | Pre-elementary (Ontario, NWT only) |
| Senior Kindergarten (SK) / Kindergarten / Grade Primary | 5 | Pre-elementary |
| Grade 1 | 6 | Elementary |
| Grade 2 | 7 | Elementary |
| Grade 3 | 8 | Elementary |
| Grade 4 | 9 | Elementary |
| Grade 5 | 10 | Elementary |
| Grade 6 | 11 | Elementary or Middle School |
| Grade 7 | 12 | Middle School or Junior High |
| Grade 8 | 13 | Middle School or Junior High |
| Grade 9 | 14 | High School |
| Grade 10 | 15 | High School |
| Grade 11 | 16 | High School |
| Grade 12 | 17 | High School (graduation year) |
Provinces vary in how they break Grades K through 12 across school buildings. A child in Ontario might attend Grades K to 6 at one elementary school, Grades 7 and 8 at the same school or a separate middle school, and Grades 9 to 12 at a secondary school. Alberta uses a Grade K to 6, 7 to 9, 10 to 12 model in most public boards. British Columbia public schools usually run K to 7 elementary, then 8 to 12 secondary. Manitoba mixes K to 6 elementary, 7 to 9 junior high, and 9 to 12 high school depending on the division.
Quebec Grades by Age (Different Structure)
Quebec runs a six-year elementary cycle and a five-year secondary cycle, with secondary school ending one year earlier than in the rest of Canada. Students then attend CEGEP (Collège d’enseignement général et professionnel) for two to three years before university.
| Grade Level | Quebec Term | Typical Age |
|---|---|---|
| Kindergarten | Maternelle 5 ans | 5 |
| Grade 1 | 1ère année du primaire | 6 |
| Grade 2 | 2e année | 7 |
| Grade 3 | 3e année | 8 |
| Grade 4 | 4e année | 9 |
| Grade 5 | 5e année | 10 |
| Grade 6 | 6e année | 11 |
| Grade 7 | Secondaire I | 12 |
| Grade 8 | Secondaire II | 13 |
| Grade 9 | Secondaire III | 14 |
| Grade 10 | Secondaire IV | 15 |
| Grade 11 | Secondaire V (graduation) | 16 to 17 |
| Post-secondary | CEGEP (2-year pre-university or 3-year technical) | 17 to 19 or 20 |
| University | Bachelor’s, usually 3 years | 19 to 22 |
The practical effect for a newcomer family with a teenager: a 17-year-old who finishes Grade 12 in Toronto in June may be a year ahead of a Montreal peer, but the Montreal peer’s CEGEP year covers the gap before university.
Pre-Kindergarten and Daycare in Canada
Canada does not have a national pre-kindergarten system. Childcare for children under 4 is delivered through a mix of licensed daycares, home daycares, family resource centres, and (in Quebec, Newfoundland and Labrador, Manitoba, and increasingly other provinces) the federal-provincial $10-a-day childcare program funded under the Canada-Wide Early Learning and Child Care agreements. The current target is $10-a-day average fees in every province and territory by March 2026.
A few provinces offer programs that bridge the gap between daycare and kindergarten:
- Ontario runs full-day Junior Kindergarten for age 4 and Senior Kindergarten for age 5 inside the public school system, free.
- Quebec runs maternelle 4 ans inside public schools for children turning 4 by September 30, free, with rollout still in progress.
- Northwest Territories runs free junior kindergarten for age 4 across the territory, fully implemented after the 2017 to 2018 expansion.
- Other provinces typically begin school at the senior kindergarten / kindergarten / Grade Primary year (age 5).
If a child is younger than the kindergarten entry age, the family is in the childcare system, not the school system, and provincial childcare ministries set the rules.
Enrolling a Child Who Arrives Mid-Year or Out of Grade
Newcomer families rarely arrive in Canada in time for a clean September start. School boards are accustomed to mid-year enrollments and follow a fairly consistent process across the country.
- Find the right school board. A child is generally assigned to the public school in the catchment area for their family’s home address. Board websites publish a “find your school” lookup. In larger metros, separate Catholic boards (in Ontario, Alberta, and Saskatchewan) and French-language boards may also be options.
- Book the registration appointment. Bring proof of the child’s age (passport, birth certificate, IRCC document), proof of address (lease, utility bill), the child’s immunization record, and any past school records translated into English or French.
- Placement assessment. For children new to Canada, school boards typically place by age first, with a language and academic assessment in the first weeks. A 9-year-old who has never attended formal school will usually be placed in Grade 4 with English-as-a-Second-Language (ESL) or French-as-a-Second-Language (FSL) support, not held back to kindergarten.
- Start school within a few days. Most boards aim to seat the child in a classroom within 5 to 10 working days of the registration appointment. ESL and settlement workers attached to the school board (the SWIS program in most provinces) can help bridge the first weeks.
If you are coming from another province with an older child mid-year, the receiving school will use your child’s previous report card to set placement, plus a placement test if the curricula differ significantly (most often the case for French and math). Cross-provincial transfers within Canada are administratively simpler than a first arrival from abroad.
Frequently Asked Questions
What age does a child start school in Canada?
Most Canadian children start kindergarten in September of the calendar year they turn 5, and Grade 1 in September of the year they turn 6. The legal compulsory age varies by province: 5 in British Columbia, New Brunswick, Nova Scotia, PEI, the territories; 6 in Alberta, Ontario, Quebec, Newfoundland and Labrador; and 7 in Manitoba and Saskatchewan.
What age can a child start kindergarten in Canada?
A child can start kindergarten in the September of the year they turn 5 (or 4 in Ontario, Northwest Territories, and Quebec, where junior kindergarten or maternelle 4 ans is offered). The cutoff is December 31 in every jurisdiction except Quebec, which uses September 30. A child born after the cutoff date waits until the following September.
Is kindergarten mandatory in Canada?
Kindergarten is mandatory in British Columbia, New Brunswick, Nova Scotia (Grade Primary), Prince Edward Island, the Northwest Territories, Nunavut, and Yukon. It is offered but optional in Alberta, Newfoundland and Labrador, Ontario, Quebec, Manitoba, and Saskatchewan, although the vast majority of families enroll because the Grade 1 curriculum assumes a year of kindergarten experience.
What grade is a 12-year-old in Canada?
A 12-year-old in Canada is typically in Grade 7 in nine provinces and the territories. In Quebec, a 12-year-old is in Secondaire I, the first year of secondary school. Children near the cutoff date who started kindergarten as 4-year-olds may be a year ahead.
What age is Grade 1 in Canada?
Children typically start Grade 1 in the September of the calendar year they turn 6. A child who turns 6 between January 1 and December 31 of a given year starts Grade 1 that September in nine provinces and the territories. Quebec uses the September 30 cutoff.
Can my child skip kindergarten and start in Grade 1?
In most provinces yes, because kindergarten is optional. In British Columbia and the four Atlantic provinces (NB, NS, PEI, NL applies the kindergarten rule less strictly) the compulsory age is 5, so kindergarten or its equivalent is required. Skipping a grade after Grade 1 is treated case-by-case by the school board through a formal acceleration assessment.
What is the difference between Junior Kindergarten and Senior Kindergarten?
Junior Kindergarten (JK) is the first year of Ontario’s two-year kindergarten program for children turning 4 by December 31. Senior Kindergarten (SK) is the second year for children turning 5 by December 31. Both are free in the public system, full-day, and play-based. Ontario, the Northwest Territories, and Nova Scotia (single Primary year only) are the jurisdictions that use the JK / SK or equivalent structure most formally.
Can I delay my child’s school start (redshirting) in Canada?
Most provinces require attendance once the child reaches the compulsory age and do not allow voluntary delay beyond that. A formal deferral is usually only available where kindergarten itself is optional or where a documented developmental reason supports the delay. The school board has the final call, and the application is typically reviewed in the spring before the September entry date.
When does the Canadian school year start and end?
The school year runs from early September to late June in nine provinces and the territories. Quebec’s school year runs from late August to late June. Most boards have a two-week winter break in late December and early January, a one-week March or spring break (two weeks for some Quebec boards), plus statutory holidays. Summer vacation covers July and August.
How do I enroll my child in school after arriving in Canada?
Find the school board for your home address, book a registration appointment, and bring the child’s passport or birth certificate, proof of address, immunization records, and past school records translated into English or French. School boards typically place newcomer children by age first and provide ESL or FSL support. Most newcomers are seated in a classroom within one to two weeks of registration.
