L1H vs L1K

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 L1H and L1K, 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.
Measure	L1H	L1K	Canada	Difference
Median household income	$73,500	$119,000	$84,000	L1H is 38% lower than L1K
Median after-tax income	$66,000	$102,000	$73,000	L1H is 35% lower than L1K
Median age	41.2	37.2	41.6	L1H is 11% higher than L1K
Unemployment rate	16.6%	13.6%	10.3%	L1H is 22% higher than L1K
Low income (LIM-AT)	13.7%	5.1%	11.1%	L1H is 2.7× higher than L1K
Average household size	2.3	3.2	2.4	L1H is 28% lower than L1K

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.

L1H is measured against Oshawa, the metropolitan area holding 100% of its residents.
L1K is measured against Oshawa, the metropolitan area holding 100% of its residents.

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

Land area	57 km²	15 km²

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	L1H	L1K
Grocery store	1 km walk	75%	60%
Public transit	1 km walk	97%	91%
Park	1 km walk	98%	96%
Pharmacy	1 km walk	55%	26%
Child care	1.5 km walk	97%	100%
Primary school	1.5 km walk	90%	83%
Secondary school	1.5 km walk	87%	83%
Library	1.5 km walk	24%	13%
Health care	3 km drive	100%	100%
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 L1H or L1K. 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.

L1H: Measured at Oshawa, 1.4 km from L1H. The index runs from 1 upward and combines ozone, fine particulate matter and nitrogen dioxide into one health-risk scale.
L1K: Measured at Oshawa, 4.2 km from L1K. 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.
