L4N vs L9S

Ontario

This page does not pick a winner. Every row shows two measurements and the gap between them. There is no score, no tally of which area “wins” more categories, and no overall result — those would be a rating of two places and the people who live in them, assembled by the layout.

Both areas are forward sortation areas, and every figure describes the whole of one. Crime is not shown here: it is reported at the metropolitan level, so for two areas in the same city it is usually the same number twice. It is on each area’s own page, with the geography it describes.

Selected 2021 Census figures for L4N and L9S, with the national figure for scale. The last column states the gap between the two areas as a direction and a size, never as a preference.

Average household size	2.7	2.8	2.4	L4N is about the same as L9S

How each area sits against the city or province around it — a different geography on each side, named in every cell. Read down a column, not across: the two columns are measured against different places and a bigger gap in one says nothing about the other.

L9S is measured against Barrie, the metropolitan area holding 100% of its residents.

Counts for each area. These describe the place and are not compared as ratios.

Share of each area’s residents with an amenity within reach, weighted by where people live. A blank is a coverage fact, not a zero.
Amenity	Within	L4N	L9S
Grocery store	1 km walk	74%	56%
Public transit	1 km walk	97%	7%
Park	1 km walk	98%	57%
Pharmacy	1 km walk	44%	28%
Child care	1.5 km walk	99%	92%
Primary school	1.5 km walk	85%	59%
Secondary school	1.5 km walk	90%	63%
Library	1.5 km walk	11%	22%
Health care	3 km drive	100%	98%
Employment	10 km drive	100%	100%

These measure how close an amenity is, never its quality. A school 500 m away is a school 500 m away — nothing here says anything about the school itself.
The proximity index is scaled against all of Canada, where 1 is the single most well-served block in the country and the national average is close to zero. It is useful for comparing places and misleading as a score.

CMHC does not survey a rental zone covering either L4N or L9S. The survey covers centres of 10,000 people and up, so there is nothing published for either area.

The air quality index is a reading at the nearest station, which may be far away — the distance is shown because it decides whether the reading describes the area at all. Facility counts are reported releases within 10 km.

L4N: Measured at Barrie, 1.6 km from L4N. The index runs from 1 upward and combines ozone, fine particulate matter and nitrogen dioxide into one health-risk scale.
L9S: Measured at Barrie, 11 km from L9S. The index runs from 1 upward and combines ozone, fine particulate matter and nitrogen dioxide into one health-risk scale.

This page carries the figures the two areas can be set against each other on. Each area’s own page has the rest — including crime, the boundary map, and every source note and caveat in full.
