L1C vs L1G

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 L1C and L1G, 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	L1C	L1G	Canada	Difference
Median household income	$109,000	$75,500	$84,000	L1C is 44% higher than L1G
Median after-tax income	$94,000	$67,500	$73,000	L1C is 39% higher than L1G
Median age	37.2	43.2	41.6	L1C is 14% lower than L1G
Unemployment rate	11.2%	16.2%	10.3%	L1C is 31% lower than L1G
Low income (LIM-AT)	5.4%	11.7%	11.1%	L1C is 54% lower than L1G
Average household size	2.8	2.3	2.4	L1C is 22% higher than L1G

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

Land area	186 km²	20 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	L1C	L1G
Grocery store	1 km walk	73%	78%
Public transit	1 km walk	49%	99%
Park	1 km walk	90%	99%
Pharmacy	1 km walk	37%	46%
Child care	1.5 km walk	95%	100%
Primary school	1.5 km walk	79%	88%
Secondary school	1.5 km walk	85%	88%
Library	1.5 km walk	18%	43%
Health care	3 km drive	99%	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.

What tenants pay, from CMHC’s survey of purpose-built rental buildings. The two areas may sit in different survey zones, or one may not be surveyed at all — that is a coverage fact and is stated rather than left blank.

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.

L1C: Measured at Oshawa, 13 km from L1C. The index runs from 1 upward and combines ozone, fine particulate matter and nitrogen dioxide into one health-risk scale.
L1G: Measured at Oshawa, 2.4 km from L1G. 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.
