Where this home is
Where this address sits, matched against open government data.
Matched to the building rather than the unit — every unit in a tower shares one coordinate.
Schools
The school boundaries this address is inside, and the schools nearest it. Boards redraw boundaries and cap programs — confirm with the board before this affects a decision.
Other schools nearby
By distance from this address, not school boundary — a school 400 m away can be in another school’s attendance area.
| School | Level | Distance | Rating |
|---|---|---|---|
| St Theresa Separate School London District Catholic School Board | Elementary | 472 m | / 10 85% met the standard |
| Byron Southwood Public School Thames Valley DSB | Elementary | 705 m | / 10 89% met the standard |
| Byron Northview Public School Thames Valley DSB | Elementary | 1.1 km | / 10 80% met the standard |
| St George Separate School London District Catholic School Board | Elementary | 1.4 km | / 10 93% met the standard |
| Byron Somerset Public School Thames Valley DSB | Elementary | 1.5 km | / 10 87% met the standard |
| John Dearness Public School Thames Valley DSB | Elementary | 1.8 km | / 10 92% met the standard |
How the rating is calculated
EQAO — Ontario’s testing agency — publishes, for each school, the percentage of students meeting the provincial standard in Grade 3 and Grade 6 reading, writing and mathematics. The rating is the average of those percentages divided by ten. A school where 72% of students met the standard rates 7.2 out of 10.
Nothing is weighted or adjusted, and schools are not ranked against each other. Where EQAO withholds a result to protect the privacy of a small group of students, that measure is left out rather than counted as zero — so a rating built on fewer than six measures says so.
What it does not measure. It is one year of standardised testing in three subjects. It says nothing about teaching, programs, or whether a school suits a particular child, and it tracks neighbourhood household income closely enough that it partly measures the neighbourhood rather than the school. Treat it as one figure among many.

H-Value
The market around this home
Detached houses in South K — 169 sales over the last five years.
How these are built, and what they cannot tell you
Each point is the median of the sales that closed in that quarter among detached houses in south k. A quarter with fewer than eight is left out rather than drawn, and the line breaks where that happens — a median over three sales is really one home’s price, and joining across a gap would draw a number nobody measured.
This is not an estimate of what this home is worth. The segment is a property type in an area; it takes no account of this home’s size, condition, renovations, lot, exposure or how it compares to its neighbours, and half the homes in any quarter sold for more than the median and half for less. It is context for a conversation with an agent, not a valuation.

The neighbourhood, by the census
Statistics Canada 2021 Census for dissemination area 35390452 — the few blocks around this address, home to 403 people. It describes the area, not this property.
Percentages are of the 245 responses in this category. Statistics Canada rounds counts and withholds small ones to keep individuals unidentifiable, so categories with too few people to publish are absent rather than shown as zero.

Work out the numbers
Everything below is calculated in your browser from figures you can change. Nothing is sent anywhere.
If you rented it out
Monthly rent starts from the median of recent 5-bedroom leases in London South. Change it to anything you like.
How this is calculated, and what it leaves out
Canadian fixed-rate mortgages compound semi-annually, not monthly, so the monthly rate here is (1 + rate/2)1/6 − 1. Most calculators use rate ÷ 12, which is the American convention and overstates the payment by tens of dollars a month.
Below 20% down, default insurance is mandatory and is added to the loan rather than paid at closing: 2.80% at 85% loan-to-value, 3.10% at 90%, 4.00% at 95%. It is unavailable at or above $1.5M, which is why 20% is a hard floor there.
Not included: vacancy, property management, capital repairs, income tax, and the fact that a lender qualifies you at a stress-test rate rather than the one you are quoted. This is arithmetic on the numbers above, not a mortgage approval or an opinion of what you can afford.
