IB, AP, Arts, SciTech and Strings all run as Regional Learning Choices Programs. Your address decides which programme you may apply to. A computer decides whether you get in.
1Kenollie Public School (JK-6)
Kenollie sits in Mineola, between Lakeview and Lorne Park, and holds a perfect 10.0 in the 2025 elementary report. It shares that top rank with several other schools, including three others in Mississauga. Its catchment is generally described as Mineola and Lorne Park, though that comes from a third-party source rather than an official Peel boundary map.
What to check before you offer
Peel does not publish street-level boundary text, and the school’s own contact page does not state its grade range. Treat both the boundary and the exact grade span as things to confirm directly with the board rather than assume.
No specialist streams identified
No French Immersion or gifted programme was identified at Kenollie. If a specialist stream matters to you, that is a reason to look elsewhere in the city rather than pay a Mineola premium for it.
2St. Rose of Lima Catholic Elementary School (JK-8)
St. Rose of Lima is the highest-rated Mississauga elementary school with a genuinely stable long record: 9.7 in the current report against a five-year average of 9.5. That consistency matters more than a single perfect score, because tied 10.0 ratings can move sharply year to year while a five-year average near 9.5 rarely does.
Access
Catholic board admission rules apply on top of address. Confirm current eligibility requirements with Dufferin-Peel before treating a catchment address as sufficient.
What could not be confirmed
The school’s exact grade range, parish affiliation and programme list were not available from its own site at the time of writing. Verify directly if any of those matter to your decision.
3John Fraser Secondary School (9-12)
Established in 1990, John Fraser is the best-scoring public secondary school in Mississauga and one of only two Peel DSB Advanced Placement regional centres, the other being Central Peel in Brampton.
The AP programme is a lottery, not a catchment
Advanced Placement here is a Regional Learning Choices Program. Peel’s rule is that students apply to the programme in their boundary based on home address, then face a two-step assessment: Grade 7 report card criteria plus a programme-specific component. Qualified applicants then go into random computer selection. Being in-boundary gets you into the draw. It does not get you a seat.
What could not be verified
The school’s street-level catchment boundaries were not obtainable, and its EQAO results are published only as PDFs that could not be read. Confirm both with Peel DSB directly.
4Lorne Park Secondary School (9-12)
Lorne Park is the most school-branded affluent neighbourhood in Mississauga, and the school is small by Peel standards at under 800 students. Feeder schools include Hillcrest Middle, Tecumseh PS, Green Glade Senior PS for Extended French, Allan A. Martin Senior PS, and the Catholic elementaries St. Christopher and St. Luke.
A reality check on the reputation
Its 7.6 rating is materially below John Fraser’s 8.8. The price premium in Lorne Park tracks the neighbourhood more than it tracks the school ranking. If you are paying specifically for measured academic results, the numbers do not support Lorne Park over Central Erin Mills.
Programmes
Regional Enhanced Program, Extended French serving all of southern Mississauga, and a Specialist High Skills Major in sports. Because Extended French draws from across southern Mississauga, that route is not tied to the Lorne Park catchment at all.
On the rank
We could not verify Lorne Park’s exact provincial rank; repeated reads of the source returned different positions. The 7.6 rating itself was consistent, so that is what we quote.
5Glenforest Secondary School (9-12)
Glenforest is one of four Peel DSB International Baccalaureate sites, alongside Erindale, Harold M. Brathwaite and Turner Fenton. It is the school Mississauga families most often ask about by name.
Why the rating understates it
The 6.8 figure is a school-wide rating covering the entire student body. The IB cohort is a small subset of that. The ranking is a poor proxy for the strength of the IB programme itself, and this is a case where the number and the reputation genuinely diverge for a defensible reason.
How IB admission actually works
IB here is a Regional Learning Choices Program. Students apply to the IB site assigned to their home address region, meet Grade 7 academic criteria plus a programme assessment, then enter random selection. Out-of-region applicants are considered only after local placements are filled. There is a published IB regional boundary map. Whether a written entrance exam forms part of the assessment could not be confirmed.

Frequently asked questions
Which is the best school in Mississauga?
On elementary ratings, Kenollie Public School in Mineola at a perfect 10.0. For a stable long-term record, St. Rose of Lima at 9.7 with a five-year average of 9.5. On the secondary side, John Fraser at 8.8 is the strongest public score in the city.
Can I get my child into IB or AP by buying in the right catchment?
No. Peel’s specialist programmes are Regional Learning Choices Programs. Your address determines which programme you are eligible to apply to, but admission runs on Grade 7 results plus a programme assessment and then a random computer draw among qualified applicants. An address buys a lottery ticket, not a seat.
Is Lorne Park worth the premium for the school?
Not on the measured results alone. Lorne Park Secondary rates 7.6 against John Fraser’s 8.8. The Lorne Park premium is a neighbourhood premium that happens to include a school, not the other way round.
Does Peel District School Board accept these rankings?
No. Peel DSB publishes a formal objection arguing that EQAO-only rankings give an incomplete and distorted picture, that there is no evidence ranking schools improves learning, and that they make differences between schools look larger than they are. That is worth weighing before you make a purchase decision on a rating alone.
How much is the school premium on a Mississauga house?
There is no credible current figure. The numbers circulating online trace back to 2015 and 2017 sources with no stated methodology, one of which came from a brokerage that no longer exists. Anyone quoting you a precise Mississauga catchment premium is extrapolating.

Ratings are from the Fraser Institute Report Card on Ontario’s Secondary Schools 2025 (published November 2025) and Report Card on Ontario’s Elementary Schools 2025 (published January 2026), both based on 2023/24 EQAO data. Rankings are published annually and are formally disputed by several Ontario school boards, which argue they ignore special education needs, English language learners and household income. Verify any individual figure at compareschoolrankings.org and confirm catchments with the board’s own address lookup before relying on them.
