Toronto school catchments, explained
If you’re trying to figure out which school your child can attend, the word you keep running into is “catchment.” Here’s what it actually means in Toronto, how to check yours across both public boards, and what to confirm with the board before you commit to an address.
What a catchment actually is
A catchment is the geographic area a school is responsible for serving. You’ll also see it called an “attendance boundary,” a “home school area,” or a “designated area” — same idea. Every residential address in Toronto sits inside a boundary for a designated public school, and children who live in that area have the right to attend that school. Boundaries are drawn by each school board, they don’t line up with neighbourhood names or postal codes, and they can differ for elementary, middle, and secondary school — so one address can fall into several different boundaries at once.
The closest school is not always your school
This is the trap that catches the most Toronto families. It feels obvious that you’d attend whichever school is nearest — but boundaries don’t work by straight-line distance. A school two blocks away can belong to a different catchment, while your designated school is further off. Boundaries follow lines the board has drawn around capacity, geography, and history, not a radius around your door. Never assume the closest school is your school. Look up the actual boundary for your specific address.
How to check yours
Each board has its own official lookup tool. For public schools, the TDSB’s Find Your School tool lets you enter your home address and returns the school designated to serve it. For Catholic schools, the TCDSB’s school locator does the same for its elementary and secondary schools. Enter the full street address, not just the neighbourhood — a single street can straddle two boundaries.
Schoolward is independent — we’re not affiliated with the TDSB, the TCDSB, or the City of Toronto — so we always point you back to the boards to confirm. What we add is a single view: checking your address on Schoolward shows the likely catchments across both public boards at once, so you don’t have to run the same address through two separate tools to see your options.
What being “in catchment” guarantees — and what it doesn’t
Living inside a school’s boundary gives your child the right to a space at that designated school. That’s the core guarantee, and it’s a real one. What it does not guarantee is admission to every program that happens to run inside that building. Specialized and optional programs — French Immersion, arts or STEM streams, gifted placements, and similar — have their own admissions processes, application windows, and sometimes assessments or lotteries. Being in the catchment secures the regular local program, not automatic entry to a special one. If a specific program is the reason you want a school, treat it as a separate application, not something the boundary hands you.
Out-of-area and optional attendance
If your designated school isn’t the one you want, both boards let families apply to attend a school outside their home area — the TDSB calls this optional attendance or out-of-area admission. The important thing to understand is that it is never guaranteed. Placement depends on whether the school has space left after local students are accommodated, and schools have to stay within their enrolment limits. Applications open in a set window each year (the TDSB’s out-of-area application typically opens in the winter for the following September), one choice is usually allowed, and if you’re admitted, transportation is your responsibility, not the board’s. Plan around the window, and have your designated school as the fallback, because a space may simply not be there.
Moving mid-year
Boundaries are tied to where you live, so moving changes your designated school. If you move within Toronto during the year, your child’s right shifts to the school for your new address — though many families ask to finish the term or year at the current school, which schools may accommodate depending on space. If you’re moving into Toronto, register with the board once you have a confirmed address. Don’t assume a mid-year move keeps the old school by default; confirm the plan with both the current and the new school so there’s no gap in your child’s placement.
What to verify with the board before you sign
A catchment can change between when you tour a home and when your child starts school. Before you sign a lease or accept an offer on a property because of a school, confirm these four things directly with the board — not with a listing, an agent, or an old map.
Boundary. Confirm the exact address falls in the school you think it does — boundaries get reviewed and redrawn, so verify the current one, not last year’s.
Program. If you want a specific program (immersion, gifted, arts), ask whether it runs at that school and how admission works — it may not be tied to the boundary at all.
Capacity. Ask whether the school is at or over capacity. A designated right still stands, but crowding can affect placement, portables, or future boundary reviews.
Transportation. Ask whether busing is provided for your address. Being in catchment doesn’t always mean transportation is included, especially for out-of-area placements.
Start with your address
The fastest way to see which catchments an address falls into is to check your address — it pulls the likely designated schools across both public boards into one view. From there you can browse schools to compare your options. Then confirm anything that matters directly with the board before you sign.
