Saint-Léonard is the Montreal borough where the plex is the rule and the single-family home the exception. That changes financing, inspection, marketing and the way a price is set.
What moves prices here
The stock first. According to the household and housing profile published by Ville de Montréal from custom 2021 census data from Statistics Canada, the borough counts 31,265 private households. Dwellings in a duplex or a building of fewer than five storeys account for 82.2% of occupied dwellings, against 70% for the City of Montreal as a whole. Single-family homes account for 9.6%, against 13.9% for the city. And 65.0% of households are renters, against 63.6%. In 2021, 1,815 occupied dwellings, or 5.8%, needed major repairs.
That stock has a date. The city places the borough’s housing boom between 1955 and the mid 1970s, with the population going from 925 residents in 1956 to 52,040 in 1971. The direct consequence: here, you are usually buying an income property, under rules that are not those of a single-family home. The first income property guide sets out the down payments CMHC requires depending on whether you occupy the building.
Then comes access. Autoroute 40, the Métropolitain, crosses the borough from east to west and splits it in two, and Autoroute 25 runs just to the east, in Anjou. Rue Jean-Talon Est is the commercial artery: Ville de Montréal counts more than 240 businesses along it.
Then the metro, which calls for precision. According to the ARTM, the blue line extension adds five stations over nearly 6 kilometres between Saint-Michel station and the Anjou borough. As of 23 September 2026, the STM states on its project page that the inauguration is planned for 2031. Two stations are in Saint-Léonard: Césira-Parisotto, at Jean-Talon and Lacordaire, and Madeleine-Parent, at Jean-Talon and Langelier. A third, Mary-Two-Axe-Earley, is planned at Jean-Talon and Viau. That is an announced timeline, not a promise, and until then it is a worksite: on 7 July 2025 the STM launched the 814 Jean-Talon Est / Bélanger shuttle for the affected area. Lines 32 Lacordaire and 33 Langelier are already frequent bus lines.
The market, finally. According to QPAREB statistics produced by the Centris system, the island of Montreal recorded 179 sales of plexes of 2 to 5 dwellings in August 2026, down 5% year over year, with 1,622 active listings, up 18%, a median price of $870,000, down 1%, and an average selling time of 54 days. That is the whole island, not your street.
The sectors
Jean-Talon Est is the commercial spine and, for a few more years, the worksite spine: noise, detours and parking get negotiated today.
Viau, to the west, will get the Mary-Two-Axe-Earley station. It is also the address of Laurier Macdonald High School, at 7355 boulevard Viau, run by the English Montreal School Board.
Lacordaire is the civic core: the borough hall and the library sit at 8400 and 8420 boulevard Lacordaire, and parc Wilfrid-Bastien at 8255.
Langelier is the sector that will change the most. Ville de Montréal adopted a master development plan for 35 hectares east of boulevard Langelier, between Autoroute 40 and the Anjou and Mercier-Hochelaga-Maisonneuve borough limits: 6,000 to 8,000 dwellings and 100,000 square metres of economic activity space by 2050, around the future Madeleine-Parent station.
Port-Maurice and Grande-Prairie are the two reference neighbourhoods Ville de Montréal uses here: 17,790 and 13,475 households in 2021. The share of single-family homes reaches 10.9% in Grande-Prairie, against 8.5% in Port-Maurice.
Selling in Saint-Léonard
A plex sells on its numbers: signed leases and section G, tax bills, an insurance quote, energy bills, the history of work and permits. The buyer finances real rents, not a hoped-for rent, and the lender verifies them. The comparative analysis is prepared at no charge, from comparables with the same number of dwellings in the same sector, with a frank read on what needs correcting before listing.
Buying here: what gets checked
The leases. Quebec’s rent-setting regime closely frames what you will be able to do after the purchase, and the moratorium on eviction for subdivision, substantial enlargement or change of use runs until 6 June 2027. My article on rental management sets out the notices, deadlines and recourses. All of it belongs in the return calculation before the offer.
Conversion to divided co-ownership. It is prohibited on Montreal territory. A borough council exemption remains possible in certain sectors, but Ville de Montréal specifies that an exemption is not an authorization: only the Tribunal administratif du logement can authorize a conversion.
The lead water service line. Ville de Montréal has targeted buildings of fewer than 8 dwellings built before 1970, publishes a screening map by address and makes replacement of the private portion mandatory within 24 months of the notice of non-compliance. It estimates the cost at between $1,200 and $1,400 per linear metre replaced, based on its 2022 to 2025 data.
Aluminum wiring and pyrite. Aluminum wiring was mostly installed from the mid 1960s to the late 1970s, which is the construction period here. It is permitted, but the risk is at the connections, and an insurer may require a compliance letter from a master electrician. On pyrite, the OACIQ records cases in 91 municipalities of Greater Montreal and places the east end of Montreal among the highest-risk areas; only an expert assessment under the CTQ-M200 method can settle it. See my inspection checklist.
State of repair. From the same municipal source, 1,815 occupied dwellings in the borough needed major repairs in 2021, that is 5.8% of the stock.
You also benefit from the Intégri-T guarantee, paid by the seller or by the buyer, covering up to $50,000 in latent defects for three years after the notarial deed.
