The top schools in Caledon and Halton Hills for 2027 are Macville Public School in Caledon (9.6 out of 10), Georgetown District High School (7.7), Mayfield Secondary School in Caledon (7.2), and Christ the King Catholic and Acton District School in Halton Hills (both 7.0), based on the latest Fraser Institute ratings.
This guide is for families looking at Caledon (including Bolton and Caledon East) or Halton Hills (Georgetown and Acton) who want the strongest schools for 2027. You get my five picks with their real scores and trends, how the four school boards in these towns differ, and what a home costs in each town.
How did I pick the top 5 schools in Caledon and Halton Hills?
I started with the Fraser Institute’s school ratings. The Fraser Institute, a think tank, scores each school out of 10 using provincial EQAO test results. Its latest elementary report (January 2026) ranked 3,052 Ontario schools and its latest secondary report ranked 747 high schools. I then checked each school’s score over several years, because a single strong year can be a fluke.
Two things are different here compared with bigger cities:
- Four boards, two regions. Caledon is in Peel Region, so its public schools are run by the Peel District School Board and its Catholic schools by the Dufferin-Peel Catholic District School Board. Halton Hills is in Halton Region: the Halton District School Board (public) and the Halton Catholic District School Board.
- Many small schools. Fraser’s elementary ratings are built on Grade 3 and Grade 6 test results, so a school without both grades may have no rating at all. Some rated rural schools have fewer than 20 students in Grade 6, which makes their scores jump around.
I gave weight to steady results and to high schools, because every family eventually needs one.
The five schools at a glance
| School | Town | Board | Latest rating | Ontario rank | Earlier ratings |
|---|---|---|---|---|---|
| Macville PS | Caledon (Bolton area) | Peel DSB | 9.6 | 51 of 3,052 | 9.3, 8.5, 7.8 |
| Georgetown District HS | Halton Hills | Halton DSB | 7.7 | 119 of 747 | 7.6, 7.1, 6.4 |
| Mayfield SS | Caledon | Peel DSB | 7.2 | 178 of 747 | 7.0, n/a, 6.7 |
| Christ the King CSS | Halton Hills | Halton Catholic DSB | 7.0 | 220 of 747 | 7.6, 7.1, 7.2 |
| Acton District School | Halton Hills | Halton DSB | 7.0 | 220 of 747 | 6.3, 6.0, 6.3 |

1. Macville Public School (Caledon)
What it is like: a Peel public elementary school at 7280 King Street West in Caledon. It scored 9.6 out of 10, 51st of more than 3,000 Ontario elementary schools, and has climbed every rated year, from 7.8 in 2019 to 8.5, 9.3 and now 9.6. It is the highest-rated school in either town.
Who it suits: families who want a top public elementary school in the Bolton part of Caledon. About 31% of its students were identified with special needs, a high share, so a strong score here is not about a narrow intake.
What to check: its attendance boundary. Caledon is large and rural in places, and a “Bolton” address can sit in a different school’s area. Look up the address with Peel’s School Finder before you write an offer.
2. Georgetown District High School (Halton Hills)
What it is like: a Halton public high school at 70 Guelph Street, Georgetown. At 7.7 (119th of 747) it is the highest-rated high school in Caledon or Halton Hills, and its rating has risen steadily since 2019. In its latest year, 89.6% of first-time students passed the Grade 10 literacy test.
Who it suits: families who want a range of programs under one roof. The Halton board lists Georgetown District High School as a site for French Immersion (Grades 9 to 12), the Secondary Gifted Cluster for students formally identified as gifted, and Specialist High Skills Majors, which bundle courses and co-op around a career sector.
What to check: the gifted cluster needs a formal identification through the board’s IPRC process; there is no separate application. Ask the school which Specialist High Skills Major sectors it runs, because they vary by school.
3. Mayfield Secondary School (Caledon)
What it is like: a Peel public high school at 5000 Mayfield Road, on Caledon’s southern edge near Brampton. It rated 7.2 (178th of 747), Caledon’s highest-rated high school, and 89.4% of first-time students passed the literacy test.
Who it suits: families in south Caledon, including the new subdivisions along the Mayfield corridor, and teens interested in the arts: Peel lists Mayfield as its Regional Arts program site for students north of Highway 401. My comparison of Cornerstone, Caledon Club, Southfields and Wildfield covers those communities.
What to check: Peel runs its specialized high school programs, such as IB, AP, Arts and SciTech, as Regional Learning Choices Programs. For September 2027, applications run from 3 November to 24 November 2026, marks are reviewed, and most qualified applicants go into a central random draw, with first offers on 2 February 2027. Living near a school with a program does not guarantee a seat in it.

4. Christ the King Catholic Secondary School (Georgetown)
What it is like: a Halton Catholic high school at 161 Guelph Street, Georgetown, a short distance along the same street as Georgetown District High School. It rated 7.0 (220th of 747), after 7.6 the year before, and 86.9% of first-time students passed the literacy test. Its record has stayed between 7.0 and 7.6 since 2018.
Who it suits: families who want a Catholic high school with steady results in Halton Hills.
What to check: Catholic board admission and transportation rules. Ask the Halton Catholic board what documents it needs and whether busing is available from your street.
5. Acton District School (Halton Hills)
What it is like: the Halton public high school at 21 Cedar Road, Acton. It tied Christ the King at 7.0, a big jump from about 6.0 to 6.4 in earlier years, and 88% of first-time students passed the literacy test. The Halton board lists it as a French Immersion high school and a Specialist High Skills Major site.
Who it suits: families who want Acton’s lower prices and a smaller-town high school, especially students continuing in French Immersion.
What to check: whether the improvement holds. One higher year is a good sign, not yet a trend. Ask the school about its newest EQAO results.
Which other schools in Bolton, Caledon East and Georgetown are worth a look?
| School | Town | Board | Latest rating | Note |
|---|---|---|---|---|
| Alton PS | Caledon | Peel DSB | 7.9 | About 14 in Grade 6; scored 5.7 the year before |
| St. John the Baptist | Bolton | Dufferin-Peel Catholic | 7.4 | Highest-rated Catholic elementary listed in Bolton |
| Caledon East PS | Caledon East | Peel DSB | 7.2 | About 20 in Grade 6 |
| St. Francis of Assisi | Georgetown | Halton Catholic | 6.9 | Up from 4.6 in 2022 |
| Silver Creek PS | Georgetown | Halton DSB | 6.8 | Highest-rated Georgetown public elementary |
| Humberview SS | Bolton | Peel DSB | 6.6 | 88.5% literacy test pass rate |
Source: Fraser Institute school rankings (compareschoolrankings.org), latest rating year.
Bolton’s two high schools are Humberview (6.6) and St. Michael Catholic (5.6). Robert F. Hall Catholic in Caledon East rated 5.4.
Small rural schools can post a great score one year and a weak one the next. Alton went from 5.7 to 7.9 in one year with about 14 students in Grade 6. Before you pay extra for a house because of a small school’s rating, look at at least three years of results, and check that the school is not about to change boundaries as new subdivisions fill in.
How do French Immersion and special programs work in Caledon and Halton Hills?
| Board | French Immersion starts | How you get in |
|---|---|---|
| Peel DSB (Caledon public) | Grade 1 | Apply 1 Dec 2026 to 29 Jan 2027 for September 2027; random selection; school set by home address |
| Dufferin-Peel Catholic (Caledon Catholic) | Grade 1 | Application; random selection if a school has more applicants than spaces; no busing |
| Halton DSB (Halton Hills public) | Grade 2 | Registration through the home school; 2026–27 registration has closed |
Source: Peel District School Board French programs page; Dufferin-Peel Catholic DSB French Immersion page; Halton District School Board French Immersion page (all read November 2026).
Peel’s French Immersion is half French and half English through Grades 1 to 8, and siblings get no priority in the draw. Peel also offers Extended French from Grade 7. Halton is unusual: Core French starts in Grade 1 and Immersion begins in Grade 2.
On test results, Halton’s public board is one of the strongest in Ontario. In 2025–26, 76% of its Grade 9 students met the math standard against 59% provincially, and 91% passed the literacy test against 86%.
What do homes cost in Caledon and Halton Hills?
| Home type | Caledon median | Change | Halton Hills median | Change |
|---|---|---|---|---|
| Detached | $1,180,000 | −7.3% | $1,000,000 | −8.3% |
| Semi-detached | $865,000 | −6.0% | $827,500 | +1.5% |

Detached homes cost about $180,000 less at the median in Halton Hills than in Caledon. Neither town publishes prices by school zone, so treat any “school premium” figure with caution. For areas within each town, see my guides to the best neighbourhoods in Caledon and the best neighbourhoods in Halton Hills.
If high school results are your main concern, Georgetown is the stronger bet right now: two high schools rated 7.0 or better, a Halton public board that beats the province by a wide margin, and a lower median detached price than Caledon. If you want Caledon, Macville is the standout elementary school and Mayfield the strongest high school, but check the boundary for every address, because Caledon’s growth means school areas can shift.
What to do next
- List the addresses you like and look up the assigned public and Catholic schools with each board’s school finder.
- Check three or more years of ratings for each school on the Fraser Institute site, and the newest EQAO report on the board’s site.
- If you want French Immersion in Caledon, put 1 December 2026 to 29 January 2027 in your calendar; in Halton Hills, ask your home school when Grade 2 registration opens for 2027–28.
- For a Peel specialized high school program, apply during the board’s window and plan for the chance of not being drawn.
- Compare with nearby options in my guide to the best schools in Brampton.

Georgetown District High School and Acton District School both rated 7.0 or higher in the Fraser Institute’s latest ratings.
When does French Immersion start in Caledon and Georgetown?

Dufferin-Peel Catholic Immersion also starts in Grade 1. In Georgetown and Acton, the Halton public board starts French Immersion in Grade 2.
Does living near a school guarantee my child a spot in its special program in Caledon?
No. Peel’s specialized high school programs, such as IB, AP, Arts and SciTech, are Regional Learning Choices Programs. For September 2027, students apply between 3 and 24 November 2026; marks, usually from the Grade 7 report card, are reviewed and most qualified applicants enter a central random draw. Peel applicants are offered spots first.
Is Caledon or Halton Hills cheaper for families?
Halton Hills is cheaper for detached homes. From January to October 2026, the median detached home sold for $1,000,000 in Halton Hills and $1,180,000 in Caledon, according to TRREB MLS data. Freehold townhouses were close in both towns, at about $800,000 to $820,000. Both towns saw detached prices fall about 7% to 8% from 2025.
Why do small Caledon schools have unusual rankings?
Small classes make scores jump. Alton Public School in Caledon had about 14 Grade 6 students, and its Fraser Institute rating went from 5.7 to 7.9 in one year. A few students moving in or out can swing a small school’s average. Look at three or more years of results for any Caledon or Halton Hills school before deciding.
