Do these figures describe a specific address in K4R?

No. K4R 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 Ottawa-Gatineau, Ontario part rather than for K4R?

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 K4R means Ottawa-Gatineau, Ontario part. 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 K4R?

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.

0% of K4R’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.

Two different rents, and neither one is “the rent here”.

CMHC surveys what tenants are paying — including people who have not moved in years — and only in purpose-built rental buildings of three units or more, so it leaves out rented condos, which in the largest cities is most of the market. Statistics Canada measures what is being asked in current listings, across the whole market. If you are staying put the first is closer; if you are moving, the second is.

K4R sits inside one CMHC survey zone, Eastern Ottawa Surrounding Areas.

Average rent paid in Ottawa's survey zones covering K4R (CMHC, October 2025), against average asking rent across Ottawa - Gatineau (Ontario part) (Statistics Canada, January 2026). The two are measured differently and are not comparable line by line.
Unit	Being paid (CMHC)	Reliability	Being asked (StatCan)
Studio	not published	—	$1,540
1 bedroom	$1,917	excellent (a)	$1,890
2 bedrooms	$2,181	very good (b)	$2,350
3+ bedrooms	$2,792	excellent (a)	$2,850

Reliability is CMHC’s own code for how much the sample supports the figure, from excellent to use with caution. Where several zones cover K4R, the weakest of their codes is shown.

CMHC withholds a figure when too few buildings of that size were surveyed to publish one reliably. A blank is a withheld figure, not a cheap apartment.
Neither figure is "the rent" for this area. One is a survey of buildings, the other a survey of listings, and both describe areas larger than a postal code.

Air Quality Health Index at Ottawa

1.31

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.
Station	Ottawa
Distance from K4R	32 km
Reading	1.31 — Low risk
Highest forecast	2

Measured at Ottawa, 32 km from K4R. 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 K4R. Distance is measured from the edge of the postal area, so a facility inside it shows as inside this area.

Reported releases to air, 2024, in tonnes. Quantities are estimated and reported by the facilities themselves.
Facility	Distance	Substances	Released to air
WinchesterWinchester · Other Manufacturing	9.7 km	4	22 t
Les Ateliers Beau-Roc Inc.Vars · Transportation Equipment Mfg.	2.3 km	3	9 t
TRM VarsOttawa · Cement, Lime and Other Non-Metallic Minerals	5.8 km	1	0.62 t
Permacon - MetcalfeMetcalfe · Cement, Lime and Other Non-Metallic Minerals	9.3 km	1	0.00 t

Together these facilities reported 32 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.

Ottawa-Gatineau, Ontario part · 33% lower than the national index of 75.0

Severity indexes for Ottawa-Gatineau, Ontario part, 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.

Violent Crime Severity Index	62.0	97.2	36% lower than Canada

Weighted clearance rate	33.8%	36.6%	2.9 percentage points lower 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.

Crime Severity Index for Ottawa-Gatineau, Ontario part (solid) against Canada (dashed), 2011 to 2025. In 2025 it was lower than in 2011 — 50.6 against 57.9. 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.

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.
