Equal scores share a regional position. To display ten profiles, ties are ordered alphabetically by the current common school name, ignoring the French École prefix. A tied school outside the ten-profile selection is named on the relevant list; it is not academically lower-ranked.
List coverage. English- and French-language schools are included in the regional comparison. Schools without a score in this report are not ranked here.

Your questions,

How were these catholic secondary schools selected?
This list follows scores in the 2025 Fraser Institute report for the 2023/2024 school year. We checked all 151 rated public and Catholic school records located within Halton Region: 75 public elementary, 17 public secondary, 48 Catholic elementary, 11 Catholic secondary. The census includes English- and French-language schools across Burlington, Oakville, Milton and Halton Hills. Public and Catholic schools are compared separately. Unrated schools are not treated as lower-rated schools. Regional positions are calculated by Offplan Canada from the published scores; they are not a separate Fraser Institute regional ranking. Equal scores share a regional position. To display ten profiles, ties are ordered alphabetically by the current common school name, ignoring the French École prefix. A tied school outside the ten-profile selection is named on the relevant list; it is not academically lower-ranked.
Does a higher score guarantee the best school for my child?
The Fraser Institute score measures selected academic indicators. It is one starting point for research, not a complete assessment of teaching, student support, wellbeing or school fit. Consider programs, learning support, travel arrangements and your child’s needs alongside the academic results.
Are the linked new home developments inside these school boundaries?
The developments on each school guide are grouped by municipality. They are not represented as inside the school’s attendance boundary or as eligible for admission. Confirm the exact home address and registration requirements with the school board.
