Kept: publicly funded schools of six boards (Halton DSB, Halton CDSB, Peel DSB,
Dufferin-Peel CDSB, Conseil scolaire Viamonde, Conseil scolaire catholique
MonAvenir) in Burlington, Halton Hills, Milton, Mississauga or Oakville.
383 schools.

City of each school: taken from the community in its address ("City"), not
from the workbook's "Municipality" column, which is wrong for some schools.
The postal code and the coordinates must agree with it; coordinates are
checked against Ontario's municipal boundaries (Ministry of Natural
Resources, "Municipal Boundary - Lower and Single Tier", https://ws.lioservices.lrc.gov.on.ca/arcgis2/rest/services/LIO_OPEN_DATA/LIO_Open03/MapServer/14,
effective 2024-02-15, sha256 d4c51e0716c37e2f301fffdbc91314ab2488f0f3daa46b8d76981f03abb90fa5,
Open Government Licence – Ontario) and against OpenStreetMap (ODbL) schools
of the same board and name: 372 schools compared, none more
than 200 m apart and none on another school's grounds while off its own;
362 of them sit inside their own school's outline. Schools sharing an
address must sit within 300 m of each other.
On 2026-10-29 every position was also compared, by hand, with the school's
own OpenStreetMap site and with its municipality's address point for its
address (Mississauga, Milton, Oakville and Burlington open data). A school
off its own site and either on another school's grounds or more than 100 m
from its address point (which lay inside the site) was moved to that address
point, and the one school placed by estimate (not yet on OpenStreetMap) was
moved to its address point; each is listed under "Corrected by hand" with its
sources. Schools on their own site, or at its edge and within 100 m of their
address point, are shown where the workbook puts them, unless the pin is on a
house lot: on 2026-10-30 one such pin (737147, Our Lady of Fatima CES, 18 m
off its site) was moved to its address point the same way.
St. Veronica CES (709332) was checked the same day and left as published: its
pin is at the edge of the school site that OpenStreetMap labels "St. Kateri
Tekakwitha Catholic Secondary School" (way/1138047934), and the Town of
Milton's address point for 675 Kennedy Circle lies inside that site, 74 m
from the pin; St. Kateri Tekakwitha CSS itself is at 1125 Kennedy Circle.
No OpenStreetMap school of the same name to compare with (11); their
position is checked against their city and postal code only (a school marked "corrected" was
found misplaced by hand and is placed from its address; see "Corrected by hand" below):

Street names corrected by hand (a typo in the workbook's street; house number,
postal code and position unchanged):
  810355 "311 Salvoline Blvd" -> "311 Savoline Blvd". Source: HCDSB, the school's contact page elem.hcdsb.org/queenofheaven/contact-us/ ('311 Savoline Blvd, Milton, Ontario, L9T 7M4', read 2026-10-29); the Town of Milton's address points (api.milton.ca Datasets/Address_Pts, read 2026-10-29) have 311 SAVOLINE BV and no street named Salvoline.
Shown under the name the board now uses (the workbook has an early or
placeholder name, which the school's page still shows and search still finds):
  847380 "ÉÉC Mississauga" -> "École élémentaire catholique Sainte-Kateri-Tekakwitha". Source: Conseil scolaire catholique MonAvenir: the school's site skt.cscmonavenir.ca (name; 5450 Festival Drive, Mississauga L5M 0G6; kindergarten to Grade 6) and the board's release of 2026-09-08, 'Rentrée scolaire 2026-2027 au Conseil scolaire catholique MonAvenir' (cscmonavenir.ca), both read 2026-10-28.
Left out by hand (no attendance area a family could buy or lease into):
  506613 Peel Alternative - South Elementary (referral-only program)

  736228 St. Oscar Romero School (referral-only program)

  951404 West Credit Secondary School (application-only regional program)
  958431 Peel Alternative South ISR (referral-only program)
Left out by the workbook's special condition: "Adult" and "Online School".
A school with any other special condition (for example "Alternative" or
"Vocational/Occupational") stops the refresh until it is reviewed: left out
by number (above), or kept with the review recorded (none is kept).
A school whose name reads like an alternative, re-engagement or adult program
stops the refresh until it is reviewed, and so does a left-out number that
changes its name or disappears.
Columns read: Board Number, Board Name, School Number, School Name, School Special Condition Code, School Level, School Language, Grade Range, Street, Municipality, City, Postal Code, Latitude, Longitude, Extract Date.
The workbook's achievement (EQAO) and student demographic columns are not read
or published: the site does not rank schools and does not describe students.
Rows left out, by reason (every row of the six boards whose address is in one
of the five cities, or that the workbook's Municipality column files under one
of them, is either one of the 383 schools or counted here once):
  application-only regional program: 2
  referral-only program: 7
  special: Adult: 1
  online school: 1
  special: Online School: 1
  special-education placement: 1
  address outside the five cities: 1
Name typos fixed by exact match: "St. Giovanni Scalabrini Catholic School School" -> "St. Giovanni Scalabrini Catholic Elementary School"; "St. Kateri Tekakwitha Catholic Secondary Catholic School" -> "St. Kateri Tekakwitha Catholic Secondary School"; "St. James Catholic Global Learning Centr" -> "St. James Catholic Global Learning Centre".

Not included: school attendance areas (catchments). They are set by each school
board and change from year to year. The tool shows one board's areas: the Halton
Catholic District School Board's (HCDSB), for the 2026-27 school year only, with
HCDSB's written permission (2026-11-02). They come from HCDSB, not from this
list; see /data/hcdsb-areas-method.txt. No other board has given permission, and
none publishes its boundary data under a licence that allows reuse on another
website, so for every other board the tool links to the board's own address look-up instead. A school that opened after the 2024-25 school year
may not be in the file yet, and some newer schools appear in it under early or
placeholder names; each board's own site is the current source.
