Of those, 2 are charter schools, giving families genuine alternatives to the traditional neighbourhood assignment model.

Schools must report at least five campuses in a city to appear in this listing, which is why very small towns may redirect to the broader county or state view.

Ontario High School accounts for 24.7% of all Ontario public-school enrollment
That concentration means Ontario-wide averages can mask substantial variation outside the dominant entity. Grade level: High. A dominant campus often anchors a city's program landscape and absorbs a disproportionate share of district capital and staffing decisions. When one entity dominates a region's footprint, its programmatic and budget decisions effectively set policy for a majority of the affected population.
Ontario school enrollment varies 7.9× across entities
Ontario school enrollment ranges from 90 students (lowest) to 709 students (highest), a spread of 619 students. That relatively narrow ratio reflects an unusually homogeneous school portfolio for a city this size. Per-school staffing, programme depth, and capital-renovation cycles often diverge inside the same city based on enrollment shape, a 200-student magnet runs a different operational model than a 2,000-student comprehensive high school.
Ontario has higher-than-average Title I eligibility — 88.5% of the population qualifies for free or reduced-price lunch
free or reduced-price lunch eligibility is the federal threshold for Title I funding allocations, established under the Every Student Succeeds Act (ESSA, 2015). Eligibility here is a supermajority of the population — well past the 75% concentration-grant threshold that unlocks extra funding on top of the basic Title I formula. Regions with eligibility this high typically draw a substantially larger federal funding share relative to their local tax base, which can either offset or reinforce existing gaps depending on allocation policy.
Ontario student-teacher ratio is 17.3:1 — near the typical range (US average ~15.7) — aligned with the U.S. average of approximately 15.7:1
student-teacher ratio is the simplest comparative metric but it does not capture the full picture: the ratio counts FTE classroom teachers against total enrollment, push-in specialists, English-language aides, special-education co-teachers, and counselors are not included in most reporting Variation between sub-units within Ontario is typically wider than the Ontario-aggregate figure suggests.
Ontario has higher-than-average charter school authorisation eligibility — 22.2% of the population qualifies for charter-school enrollment options
charter-school enrollment options eligibility is the federal threshold for charter school authorisation funding allocations, established under the state-specific charter law. Eligibility here is approaching the 30% concentration-grant threshold; it does not yet unlock the extra funding tier but sits meaningfully above the baseline 10% majority mark. Regions with eligibility this high typically draw a substantially larger federal funding share relative to their local tax base, which can either offset or reinforce existing gaps depending on allocation policy.
