Sector A, sector L, sector P: in Brossard, people often refer to their neighbourhood with a single letter. This guide is for newcomers, home buyers and anyone who wants to understand this system, unique in the region: where it comes from, which letters exist, how it’s used day to day and how to find your sector. We clearly separate what comes from City documents from less official historical landmarks. Last checked: October 2026.
At a glance
- Brossard is divided into sectors identified by a letter, and the names of the streets in a sector begin with that letter.
- The City’s website offers a choice of 17 sectors: A, B, C, E, I, J, L, M, N, O, P, R, S, T, V, X and Y.
- The system dates back to a 1960s development plan designed to make it easier to find your way around.
- Major roads that cross several sectors are exceptions to the letter rule.
- Sectors are still used today: waste collection, English school zones, real estate searches.
The principle: one letter per sector
Within a given sector, street names begin with the sector’s letter. If you live on a street whose name begins with an “A”, you are, in principle, in sector A. The draft toponymy (place-naming) policy published by the City of Brossard in 2025 confirms this: it notes that Brossard’s streets are characterized by names beginning with a letter according to the sector, and requires that the sector’s letter and theme be respected when naming a new public or private street.
The exceptions are major roads, such as Boulevard Taschereau, Boulevard de Rome or Boulevard Lapinière, which cross several sectors and therefore don’t follow the letter of the neighbourhood they pass through. An address on a major road doesn’t, on its own, tell you which sector you’re in.
Where does this system come from?
According to the historical sources consulted, the lettered sectors stem from a 1960s development and zoning plan prepared by the engineering firm Beauchemin, Beaton et Lapointe. Brossard, incorporated in 1958, was growing very quickly at the time, on a territory without a regular street grid like Montreal’s. Giving each sector a letter made it easier to find your way around.
The list of sectors
The sector selector on the City of Brossard’s website shows 17 letters. The 2025 draft toponymy policy also mentions a letter W, while still referring to 17 sectors: if in doubt about a specific address, the City’s official map prevails.
Where documented, the table below gives historical landmarks drawn from secondary sources (encyclopedias and historical compilations), not from the City. They provide a general idea, nothing more.
| Sector | Historical landmarks (secondary sources) |
|---|---|
| A | Partly corresponds to the former Saint-Alphonse and Notre-Dame-du-Sacré-Cœur neighbourhoods; some buildings predate the city’s founding. |
| B | Associated with the former Vanier and Southgate neighbourhoods. |
| C | Not documented in the sources consulted: see the City’s map. |
| E | Not documented in the sources consulted: see the City’s map. |
| I | Industrial park. |
| J | Not documented in the sources consulted: see the City’s map. |
| L | Not documented in the sources consulted: see the City’s map. |
| M | Associated with Aster (Asterville); among the first neighbourhoods built after 1958. |
| N | Not documented in the sources consulted: see the City’s map. |
| O, R, S | Associated with the historic Brosseau-Station area; some buildings in sector R predate the city. |
| P, V | Associated with Marie-Victorin and Parkland; sector V is among the first neighbourhoods built after 1958. |
| T | Associated with Champlain. |
| X, Y | Sparsely populated: mostly main roads and industrial streets. |

Municipal services
The City of Brossard’s website lets you choose your sector to get information tailored to your address. This is especially useful for collection schedules: see our guide to garbage, recycling and compost collection.
English schools
The Riverside School Board defines its priority zones in Brossard by sector letter. For the 2026-2027 school year, for example, Harold Napper Elementary School covers sectors B, C, I, J, L, M, N and O, St. Jude School covers sectors A, M, N, O, P, T and V, and St. Lambert School covers sectors P, R, S, T and V. Zones change from year to year: check the school board’s document for the year in question. On the French side, the Centre de services scolaire Marie-Victorin assigns the neighbourhood school by address, using street indexes. See Brossard’s elementary schools and high schools.
Real estate searches
Property listings in Brossard very often mention the sector. Comparing prices sector by sector helps you spot differences, but it doesn’t replace a visit or a professional’s advice. See house and condo prices in Brossard.
How to find your sector
- Look at the first letter of your street name: in the vast majority of cases, that’s your sector.
- If you live on a major road, find the nearest cross street: its letter tells you the sector.
- If in doubt, check the sector map on the City of Brossard’s website or contact the City’s citizen services.
- For schools, never rely on the letter alone: check your exact address with the school service centre or school board.
Sectors, electoral districts and postal codes: don’t mix them up
A lettered sector is not an electoral district. For municipal elections, the City is divided into numbered electoral districts whose boundaries mostly follow highways, boulevards and railway lines. Sectors aren’t tied to postal codes either. Keep these three divisions separate when looking for official information.
Frequently asked questions
How many sectors are there in Brossard?
The City’s website lists 17 sectors: A, B, C, E, I, J, L, M, N, O, P, R, S, T, V, X and Y. A 2025 document also mentions the letter W; the City’s official map remains the reference.
Why aren’t all the letters of the alphabet used?
The sectors were laid out according to how the territory developed, not to cover the whole alphabet. Some letters simply aren’t used.
What is the best sector in Brossard?
There’s no one-size-fits-all answer. It all depends on your priorities: school, proximity to the REM, parks, budget. Our article on neighbourhoods for families offers a set of criteria.
Does the sector affect property taxes?
Not directly: the bill depends mainly on the value entered on the assessment roll and the property category. However, some taxes or charges tied to a specific location may be added; check your tax bill or the City’s taxation by-law. For an estimate, use our property tax calculator.
Can a new street use a different letter?
The City’s draft toponymy policy calls for respecting the sector’s letter and theme for any new public or private street.
