Do these figures describe a specific address in J4X?

No. J4X 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 Montréal, Quebec rather than for J4X?

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 J4X means Montréal, Quebec. 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 J4X?

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.

6% of J4X’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.

J4X sits inside one CMHC survey zone, Boucherville/Brossard etc..

Average rent paid in Montréal's survey zones covering J4X (CMHC, October 2025), against average asking rent across Montréal (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	$971	good (c)	$1,270
1 bedroom	$1,207	very good (b)	$1,530
2 bedrooms	$1,455	very good (b)	$1,900
3+ bedrooms	$1,635	very good (b)	$2,390

Reliability is CMHC’s own code for how much the sample supports the figure, from excellent to use with caution. Where several zones cover J4X, the weakest of their codes is shown.

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.

Facilities that reported releasing a listed substance to the National Pollutant Release Inventory, within 10 km of J4X. Distance is measured from the edge of the postal area, so a facility inside it shows as inside this area.

32 facilities within 10 km of J4X reported to the inventory. The 12 that released the most to air are listed; the total below covers all of them.

All 32 facilities within 10 km — including the 20 not listed above — together reported 2,575 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

61.3

Montréal, Quebec · 18% lower than the national index of 75.0

Severity indexes for Montréal, Quebec, 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	Montréal, Quebec	Canada	Compared
Crime Severity Index	61.3	75.0	18% lower than Canada
Violent Crime Severity Index	92.0	97.2	5% lower than Canada
Non-violent Crime Severity Index	49.5	66.8	26% lower than Canada
Weighted clearance rate	40.1%	36.6%	3.5 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	Montréal, Quebec	Canada	Compared
All violations	4,148 per 100,000	6,065 per 100,000	32% lower than Canada
Criminal Code, excluding traffic	3,641 per 100,000	5,585 per 100,000	35% lower than Canada
Violent Criminal Code	1,277 per 100,000	1,443 per 100,000	12% lower than Canada
Property crime	1,982 per 100,000	3,141 per 100,000	37% lower than Canada

Crime Severity Index for Montréal, Quebec (solid) against Canada (dashed), 2011 to 2025. In 2025 it was lower than in 2011 — 61.3 against 79.8. 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.
