For families moving within Mississauga, the school conversation is often just as important as the home itself. A beautiful house matters, but the right neighbourhood package matters more: schools, sports, parks, trails, commutes, community feel and the ability for kids to grow into the area over time.

This guide looks at school performance using several public sources, including the Fraser Institute school report cards, EQAO school-result tools, school board program information and private-school comparison resources. The focus is Mississauga overall, but the recommendations are weighted toward the areas I work in most often: Lorne Park, Port Credit, Clarkson and Lakeview.

How to read school rankings without overreacting to them

School rankings are useful, but they are not the whole story. Fraser Institute rankings are largely built from provincewide test results, while EQAO provides a direct school-by-school and board-level view of reading, writing and math achievement. These are important signals, but they do not measure every factor families care about: school culture, special education support, athletics, arts, French, IB, private-school fit, commute, boundary changes or how well a specific child will thrive.

Quick answer: which schools stand out?

If you are looking strictly at academic ranking signals, Kenollie Public School stands out as the strongest elementary result in Mississauga, while John Fraser SS, ISNA High School and Olive Grove High School sit near the top of the broader Mississauga secondary list. But for families targeting South Mississauga, the practical standouts are Kenollie PS, Lorne Park SS, Port Credit SS, St. Christopher, St. James and Mentor College.

Comparison table: schools worth shortlisting

Best South Mississauga public school anchors

Kenollie Public School — Mineola / Port Credit

Kenollie is the headline elementary school for many families considering Mineola, Port Credit and the eastern edge of the Lorne Park conversation. The Fraser-based 2025 data shows Kenollie with a 10.0/10 rating and a #1 out of 3,052 Ontario elementary schools ranking. From a real estate perspective, the key point is that Kenollie’s catchment is relatively small and sits in a premium pocket.

Lorne Park Secondary School — Lorne Park

For South Mississauga high schools, Lorne Park SS is the public-school anchor. Fraser-based 2025 data places Lorne Park SS at 7.6/10, ranked #130 of 747 Ontario secondary schools, which puts it in the upper tier provincially. Lorne Park works especially well for families who want a traditional established neighbourhood with strong resale appeal and a high-quality public secondary path.

At the elementary level, Lorne Park deserves a more detailed look than rankings alone. Families often ask about Lorne Park Public School (sometimes casually referred to as Lorne Park Elementary), Tecumseh Junior Middle School, Whiteoaks Public School for French Immersion, Hillcrest Middle School and Owenwood Public School. These schools matter because they connect directly to the day-to-day family experience: walkability, neighbourhood friendships, after-school logistics and the pathway toward Lorne Park SS. Boundaries and programs can shift, so buyers should always verify the address-specific school assignment before making an offer.

In practical terms, Lorne Park often appeals to buyers because there are multiple strong public-school pathways within a highly established family neighbourhood. That mix of school choice, mature streetscapes and long-term resale appeal is a big part of why the area remains so popular with move-up families.

Port Credit Secondary School — Port Credit

Port Credit SS is another key South Mississauga option. The 2025 Fraser-based summary shows 7.2/10, ranked #178 of 747 Ontario secondary schools. What makes Port Credit particularly appealing is not just the rating; it is the program mix and the neighbourhood lifestyle: GO Train access, waterfront parks, restaurants, village feel, trails and community events.

Catholic school options in South Mississauga

Catholic school demand is very real in South Mississauga, especially for families comparing Lorne Park, Clarkson and Lakeview. St. Christopher Catholic Elementary School in Clarkson shows a 7.4/10 Fraser-based rating. St. James shows an even stronger 8.4/10 Fraser-based result in Mississauga. Mary Fix is also relevant for Port Credit/Lakeview families.

At the secondary level, Iona Catholic Secondary School is the key Clarkson/Lorne Park-area Catholic high school. Its 2025 Fraser-based rating is 6.2/10, but I would not evaluate Iona on the rating alone. It is a major local Catholic secondary option and is also associated with arts programming and the broader Dufferin-Peel Catholic system.

Private school options in Mississauga

Mentor College is one of Mississauga’s best-known private schools and is ranked #1 among Mississauga private schools in the Our Kids five-year ranking summary. It serves JK to Grade 12 and is particularly relevant to families in Port Credit, Mineola, Lorne Park and Lakeview because of its location and long-standing reputation.

For families considering private education in South Mississauga, I would keep the private-school conversation practical: compare curriculum fit, school culture, commute, class size, athletics, arts, university preparation and how the student actually feels when touring the school. Rankings can help start the conversation, but the right private-school decision is usually more personal than purely statistical.

What this means for buyers in Lorne Park, Port Credit, Clarkson and Lakeview

Lorne Park

Lorne Park remains one of the strongest family neighbourhoods in Mississauga because it combines school reputation, mature lots, privacy, prestige, parks and access to the lake.

Port Credit

Port Credit is a powerful choice for families who want a more walkable, connected lifestyle. Kenollie and Mentor College also strengthen the broader Port Credit/Mineola school conversation.

Clarkson

Clarkson is more nuanced. Some pockets offer excellent value compared with Lorne Park, but school pathways can vary significantly street by street.

Lakeview

Lakeview is increasingly attractive because of revitalization, lakefront investment and proximity to Port Credit. School decisions here often involve comparing public, Catholic and private options nearby.
