Do these figures describe a specific address in N7T?

No. N7T is a forward sortation area — the first three characters of a postal code — and every figure here describes the whole of it. That is the finest granularity Canadian open data supports; a full six-character postal code requires a licensed Canada Post file. Conditions on one street can differ from the area average.

Why is the crime figure for Ontario rather than for N7T?

Police-reported crime is not published for postal areas anywhere in Canada. Statistics Canada publishes it by police service, aggregated to metropolitan areas and provinces, which for N7T means Ontario. There is no municipal feed covering this area, so the regional figure is the finest available.

How current is this profile?

The census figures are from the 2021 Census. The other panels carry their own dates, shown beside each one, because they are published on different schedules — crime annually, CMHC rents each October, asking rents quarterly, and the air quality index live. Each figure is labelled with the vintage it came from rather than the date you are reading it.

Does this page rank or score N7T?

No. There is no score, no grade, no star rating and no ranking against other areas. Every figure is a measurement with a source, a date and a stated granularity, and none of them are combined. The site describes places using published statistics; it does not draw conclusions about the people who live in them.

How close everyday amenities are — not how good they are. Each figure is the share of this area’s residents who have that amenity within the distance shown, weighted by where people actually live.

Share of N7T’s residents with each amenity within reach. The proximity index in the last column is scaled against all of Canada, where the national average is close to zero — read it against Canada, never on its own.

0% of N7T’s residents live in a block Statistics Canada classifies as an amenity-dense neighbourhood — one with a grocery store, pharmacy, health care, child care, a primary school, a library, a transit stop and a source of employment all in range. Nationally it is 16%. This is StatCan’s composite, not ours.

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.

Air Quality Health Index at Sarnia

2.47

Low risk · 11:00 AM EDT Thursday 13 August 2026

The Air Quality Health Index combines ozone, fine particulate matter and nitrogen dioxide into one health-risk scale. It is a reading at a station, not a measurement of any address.

Measured at Sarnia, 5.9 km from N7T. The index runs from 1 upward and combines ozone, fine particulate matter and nitrogen dioxide into one health-risk scale.

Facilities that reported releasing a listed substance to the National Pollutant Release Inventory, within 10 km of N7T. Distance is measured from the edge of the postal area, so a facility inside it shows as inside this area.

40 facilities within 10 km of N7T reported to the inventory. The 12 that released the most to air are listed; the total below covers all of them.

All 40 facilities within 10 km — including the 28 not listed above — together reported 52,916 t released to air in 2024. That is what was reported within 10 km — not what reached this area, which depends on stack height, wind and chemistry that this inventory does not model.

The inventory is threshold-based: a facility reports only when it exceeds a quantity for a listed substance. Smaller emitters, road traffic, home heating and agriculture are not in it.
Quantities are reported by the facilities themselves and are estimates, not measurements at the fence line. Being close to a facility is not the same as being exposed to what it reports.

Crime Severity Index, 2025

57.2

Ontario · 24% lower than the national index of 75.0

Severity indexes for Ontario, 2025. The Crime Severity Index weights each offence by how serious the courts treat it, so it is an index and not a count — 100 is Canada in 2006.
Measure	Ontario	Canada	Compared
Crime Severity Index	57.2	75.0	24% lower than Canada
Violent Crime Severity Index	74.9	97.2	23% lower than Canada
Non-violent Crime Severity Index	50.6	66.8	24% lower than Canada
Weighted clearance rate	39.8%	36.6%	3.2 percentage points higher than Canada

Reported incidents per 100,000 residents, 2025. These count incidents without weighting them by seriousness, so they are not comparable with the indexes above.
Violations	Ontario	Canada	Compared
All violations	4,582 per 100,000	6,065 per 100,000	24% lower than Canada
Criminal Code, excluding traffic	4,296 per 100,000	5,585 per 100,000	23% lower than Canada
Violent Criminal Code	1,078 per 100,000	1,443 per 100,000	25% lower than Canada
Property crime	2,600 per 100,000	3,141 per 100,000	17% lower than Canada

Crime Severity Index for Ontario (solid) against Canada (dashed), 2011 to 2025. In 2025 it was lower than in 2011 — 57.2 against 61.2. A change in the index can come from a change in the number of offences, in how serious they were, or in how many were reported to police.

N7T is not inside a metropolitan area that publishes crime figures, so the comparison is against Ontario as a whole.
The Crime Severity Index weights offences by seriousness and is set so that Canada in 2006 = 100. A rate per 100,000 counts incidents without weighting them. The two are not interchangeable and should not be compared to each other.
