# 1 Avenue Van Horne: A Century Between the Tracks and the Rules

# 1 Avenue Van Horne

**Site:** Entrepôt Van Horne / Van Horne Warehouse, 1 avenue Van Horne, Montréal 

**Arrondissement:** Le Plateau-Mont-Royal, at the tri-border with Rosemont–La Petite-Patrie and Outremont 

**Neighbourhood:** Mile End — north edge

## Executive Summary

A 1924 concrete-and-brick warehouse. Seven storeys, nearly windowless, crowned by one of Montreal's last steel water towers. It was built to move freight between the Canadian Pacific rail line and the road network — and now, a century later, it's the last unconverted industrial monolith on a block that has converted everything around it.

The parcel tells a story of a single unbroken use — storage, 1924 to 2022 — that outlived its economic logic by thirty years. The block tells of Mile End's post-1990 mutation from garment-and-rail district to artist enclave to Ubisoft-and-Mile-Ex tech corridor. The city ring shows the PUM 2050 designating the building an *exceptional* heritage industrial ensemble inside an employment zone where, after Lac-Mégantic, housing beside the rail line is off the table.

The gap being priced today: a vacant document depot versus an authorized floor-space ratio of 6.5, with a 120-room hotel, a guaranteed minimum of 25% artist studios, ground-floor retail, a rooftop greenhouse, and a new four-storey office building next door at 55 Van Horne. The enabling règlement — P-25-021, adopted under article 89 of the city charter — received a favourable report from the Office de consultation publique de Montréal (OCPM) in December 2025 and was on track for adoption in winter 2026.

## The Site

**The subject parcel** — 1 avenue Van Horne, lot 1 867 998 of the Cadastre du Québec — sits in the Plateau-Mont-Royal, governed by Règlement d'urbanisme 01-277. It has been vacant since 2022 and is the object of draft règlement P-25-021.

**The attached parcel** — 55 avenue Van Horne, lot 2 135 975 — holds a one-storey building slated for demolition and replacement by a contemporary four-storey office building. Same owner, Rester Management, same règlement.

**To the west** sits the Jardin du Crépuscule, a sculpture garden created by local artist Glen LeMesurier, which consultation participants flagged as at risk from construction and the planned parking ramp. **To the north**, the active Canadian Pacific rail corridor — the constraint that killed residential use on this site. **To the south and east**, the Rosemont–Van Horne viaduct and the Saint-Laurent tunnel; the City plans a transformation of the viaduct by 2030, with no public plan yet available.

## The Parcel

### Site and Ownership

The lot is an irregular sliver bounded by the CP rail line to the north, the Saint-Laurent tunnel to the east, avenue Van Horne to the south and the Saint-Urbain underpass to the west.

The ownership chain, per Héritage Montréal's heritage record: built for Wilfrid Duquette's St. Lawrence Warehousing Company, which remained owner until the early 1960s, when it passed to Van Horne Warehouse Inc. Press coverage (Le Devoir, 2025) reports that Rester Management acquired the building in 2019 — though there's a genuine conflict in the record: Le Devoir's 2022 reporting described Rester as owner "for about ten years," and Héritage Montréal describes both the 2013 proponent and the 2023 proponent as "a new owner." The sale dates, prices, and the identity of the 2013-era owner sit in the Registre foncier du Québec, which is paywalled; nothing here is drawn from it. The assessed value and matricule from the rôle d'évaluation were likewise not pulled in this pass.

### Origin Story

The building went up in 1924–1925 on land whose entire logic was the railway. The avenue itself is named for William Cornelius Van Horne, the CP president who drove the transcontinental line; the Mile End station at Saint-Laurent and Bernard had made this stretch an industrial magnet since the 1890s.

Wilfrid Duquette, a warehousing entrepreneur, built the seven-storey structure for his St. Lawrence Warehousing Co., replacing an earlier two-storey store-warehouse — a bet that the crossing of rail and road here was worth a monolith. The large ground-floor openings on both sides, bricked up since shipping containers arrived in the 1950s, recall its original role as a transshipment station between the rail and road networks. The small upper openings testify to its warehouse function. The steel water tower on the roof is a vestige of the fire-suppression system, decommissioned in 1992 and one of the last in the city.

The workforce context: the east side of the tracks was working-class Mile End, annexed to Montreal (as Ville Saint-Louis) in 1910, its economy stitched to the garment factories and freight yards along the CP line. The original architect is not identified in the public records pulled — the 1924 permit card at the Archives de Montréal would name the designer.

### Build Potential

Under the Plateau's Règlement d'urbanisme 01-277, the building is listed as a *témoin architectural significatif* (Annexe B). What's precisely documented is the authorized envelope under draft règlement P-25-021: a maximum floor-space ratio (COS) of 6.5 for 1 Van Horne and 4.6 for 55 Van Horne; a maximum height of 23.2 metres for both buildings, with the water tower, greenhouse, mezzanine and rooftop equipment excluded from the calculation; a mandatory minimum of 25% of floor area at 1 Van Horne for artist and artisan studios; the hotel capped at 50% of the complex; and a maximum of 50 interior parking units.

The delta here is unusual: the existing building already fills most of that envelope. The value gap is not unbuilt density but *unusable* density — seven floors of dark storage space versus 6.5 COS of authorized commercial use. To get there, the proposal derogates from roughly a dozen provisions of 01-277, covering height, density, permitted uses, mezzanines, awnings, mechanical equipment, parking and café-terrasse rules.

### Physical Constraints

The constraints are the story of this parcel.

**Structural:** a May 2021 preliminary structural report found a major renovation "entirely feasible" but flagged the frame and seismic capacity; an April 2023 lateral-resistance expertise concluded the existing elements are insufficient as-is, though seismic upgrading is "achievable and viable."

**Rail:** the active CP line runs hard against the north wall. After the Lac-Mégantic disaster of July 2013, building housing this close to a rail line is no longer possible — a hotel or offices, however, are. This single constraint explains why every affordable-housing demand made in consultation was structurally impossible on this lot.

**Openings:** the building is essentially windowless, its walls three brick-rows deep, making fenestration the central architectural problem of any conversion.

**Contamination:** no listing was confirmed in this pass, but La Presse notes the building stored, over a century, milling products, chemical components, furniture and archival documents — the chemical-storage interval makes a check of the MELCCFP and municipal registries worthwhile.

**Heritage:** PUM 2050 lists the building as part of an "ensemble patrimonial industriel exceptionnel," and the OCPM has recommended the City adopt a citation under the Loi sur le patrimoine culturel — an intermediate legal status that frames future interventions while opening access to financial and technical aid.

### Site Timeline

**1924–1925 — Construction** for St. Lawrence Warehousing Co., replacing a two-storey predecessor. *For four decades the building does exactly what it was built for: freight in from the CP siding, freight out to trucks, under Duquette's name painted across the parapet.*

**Early 1960s — Ownership passes**; the building becomes Van Horne Warehouse Inc. *Containerization arrives; the great ground-floor rail doors are bricked shut, and the building's transshipment function quietly dies while its storage function limps on.*

**1990 — Docu-Dépôt moves in; 2000 — Docudata.** *The warehouse's last economic act: storing paper records for a world that is digitizing them — a business model with an expiry date printed on it. The water tower is decommissioned in 1992.*

**2013 — A new owner proposes** a mixed commercial-residential conversion with near-fully-glazed façades. *Héritage Montréal puts the building on its 2014 watch list; the glass project dies. The building keeps storing boxes for another decade while everything around it converts.*

**2019 — Rester Management acquires the property** (price unverified; Registre foncier).

**2022 — The last tenants leave**; the building has been vacant since. On July 26, 2022, the first CCU application for offices and a hotel is filed. *Vacancy accelerates decay — graffiti spreads across the brick and the interior; the borough councillor warns time is running out.*

**January–February 2023 — Borough survey:** more than 10,500 participants; 74% of 10,732 respondents opposed a hotel without cultural or community space. *Rester goes back to the table: an independent concertation process runs through 2024–2025, and Les Ateliers Belleville enter the project.*

**April 8, 2025 —** Revised project receives a favourable CCU opinion with conditions. **June 17, 2025 —** The comité mixte (Conseil du patrimoine + Comité Jacques-Viger) issues a favourable opinion. **August 25, 2025 —** City council mandates the OCPM. **September–October 2025 —** OCPM consultation, 331 contributions. **December 19, 2025 —** The OCPM reports the project "generally well received," with concerns on long-term studio affordability, the absence of exclusively community space, and fit with local needs.

*The city's published schedule calls for adoption and entry into force of the règlement in autumn 2025–winter 2026; construction must then begin within 60 months of the règlement taking effect. Whether final adoption has occurred as of mid-2026 was not confirmed in the records pulled.*

## The Block

### Neighbouring Applications and Approvals

The immediate block's only active file *is* the subject complex — 1 and 55 Van Horne under one règlement. The consequential neighbouring "application" is public: the City's planned transformation of the Rosemont–Van Horne viaduct by 2030, for which no plan or budget yet exists — an unresolved variable both promoter and borough admit will reshape the site's access and public realm.

### Who's Active Here

Named actors, from public records: **Rester Management** (owner and promoter); **Thomas Balaban** (architect) and **Zébulon Perron** (designer), both Mile End-raised; **Les Ateliers Belleville (LAB)**, the nonprofit studio operator bound by a letter of intent summarized in December 2024, partnered with **AU/LAB** for the rooftop greenhouse; **Glen LeMesurier**, sculptor of the adjacent Jardin du Crépuscule; **Héritage Montréal** (Dinu Bumbaru) and **Mémoire du Mile End** (Justin Bur) as the heritage interlocutors; engineering by **Poincaré ingénierie** and **RJC Ingénierie**; borough politics carried by councillor **Marie Plourde** and, post-election, mayor **Cathy Wong**.

### The Turn

Two candidates, one block-scale and one policy-scale.

Block-scale: the 2013 glass-façade proposal — the moment the building stopped being real estate inertia and became contested ground. Héritage Montréal's 2014 watch-listing set the precedent that governs everything since: *conversion yes, erasure no.*

Policy-scale: Lac-Mégantic, July 6, 2013 — the same year — which removed housing from the possibility space and pre-wrote the answer to the loudest demand of both consultations.

The 2025 precedent now set for the block: an article-89 règlement trading heritage-sensitive design and a 25% guaranteed cultural floor for hotel-and-office density beside the tracks. Every rail-adjacent friche the comité mixte flagged for future requalification will negotiate against this template.

### Block Timeline

**1876–1911 —** Mile End station era; CP purchases the line in 1882; the avenue is named for Van Horne; industry lines the tracks. *The rail corridor sorts the district: factories and warehouses hug the line, triplex Montreal fills in behind.*

**1990s —** Deindustrialization; large industries leave the neighbourhood and new uses appear. *Cheap lofts fill with artists and studios; Mile End's cultural reputation is manufactured in exactly the kind of space the warehouse represents.*

**2000s–2010s —** Ubisoft anchors the Peck Building; Mile-Ex and Marconi-Alexandra heat up north of the tracks; consultation testimony describes tech firms like Microsoft driving up land values in adjacent Mile-Ex, pushing out residents, shops and artists. *The warehouse becomes the visible holdout — the same blind brick wall while everything around it re-glazes.*

**2013–2026 —** The two conversion attempts, chronicled above; the under-viaduct informal culture — the skatepark, the raves, LeMesurier's sculptures, the nearby Champ des Possibles — becomes the counter-narrative in every consultation.

## The City

### Governing Plans and Intent

PUM 2050, adopted in 2025, designates both lots "Activités diversifiées" — an economically dominant designation permitting commerce, offices, light industry, collective or institutional facilities and urban agriculture — and lists 1 Van Horne among heritage properties as an "exceptional industrial heritage ensemble."

The site also sits in the PDUES Marconi-Alexandra / Atlantic / Beaumont / De Castelnau territory (2013), whose non-binding orientations are to affirm the economic vocation, support mixed and diversified milieus, improve the urban landscape, and de-enclave the quartiers while improving mobility. The project is a near-literal execution of those four lines.

### Policy Changes With Value Impact

**Article 89 authorization route (↑):** removes the referendum risk that hangs over any dérogation-heavy Plateau project; the borough explicitly evoked a process avoiding popular referendums in favour of public consultation.

**Post-Lac-Mégantic rail-proximity restrictions (↑ commercial / ↓ social license):** housing is excluded, so the highest permitted use — hotel and office — faces no residential-inclusion obligation, but the project absorbs continuous gentrification criticism for it.

**Recommended heritage citation (↑↓):** frames future interventions while giving access to financial and technical aid — constraint and subsidy in one instrument.

**Artist-studio funding (↓ risk):** the OCPM notes the City's existing studio-support program has expired and recommends the City finance the studios and back a fiducie d'utilité sociale; until funded, the 25% cultural floor's *affordability* is a promise, not a mechanism.

**Règlement pour une métropole mixte:** not triggered — no residential component.

### Incentives, Infrastructure and Decision-Makers

Transit is the weak ring: bus 161 on Van Horne (nearest stop about 250 metres away), bus 55 on Saint-Laurent and Saint-Urbain, and métro Rosemont more than 700 metres away by an unfriendly walk. The Réseau-Vert linear park and the cycling network touch the site, but the Saint-Laurent approach is perceived as particularly accident-prone. Permits are conditional on a cost-sharing infrastructure agreement between the promoter and the borough. Decision-makers by role: the borough mayor (Plateau), the borough urban-planning councillor, the Service de l'urbanisme et de la mobilité, and city council, which holds the article-89 pen.

### City Timeline

**2013 —** PDUES adopted after OCPM consultation. *The city formally names the rail-adjacent sectors as its next employment frontier.* **2013 —** Lac-Mégantic. *Rail-side housing dies province-wide.* **2025 —** PUM 2050 adopted; project mandated to the OCPM on August 25. *The new plan arrives just in time to be quoted on both sides of the hearing.* **November 2025 —** Municipal election; the OCPM president's transmittal letter addresses a new administration counting on better collaboration between boroughs and central services. **Winter 2026 —** Scheduled adoption window. **2030 —** Viaduct transformation horizon.

## The Narrative Arc

It was built to stand between two networks. In 1924, Wilfrid Duquette put seven storeys of concrete and brick on a sliver of land where the Canadian Pacific tracks met the road, because in that Montreal, the fortune was in the transfer — boxcars on one side, trucks on the other, and the St. Lawrence Warehousing Company's name painted across the top. The walls were three bricks deep and almost windowless, because merchandise doesn't need a view.

What broke wasn't the building. It was the transfer itself. Shipping containers arrived in the fifties and the great rail doors were bricked shut. Industry drained out of Mile End through the eighties and nineties, and the warehouse fell back on the last thing a windowless box can do: it stored paper. Docu-Dépôt, then Docudata — archives for companies, in the decades when every archive was being scanned. The water tower was switched off in 1992. The business model expired slowly, and in 2022 the last tenants carried out the last boxes.

The long middle was the strange part: for thirty years, the most visible building in Mile End was also its emptiest, a red-brick paquebot looming over a neighbourhood that turned artistic, then expensive, all around it. A glass-façade conversion was floated in 2013 and beaten back. The tracks that built it now blocked its most obvious future — after Lac-Mégantic, no one could put homes that close to the line.

The turn came when Rester Management, the architect Thomas Balaban and, eventually, ten thousand consulted neighbours negotiated what a windowless monument is allowed to become: a hotel that can't be housing, studios guaranteed a quarter of the floor, a restored water tower, a public rooftop.

What it is now, in one sentence: a vacant, exceptional heritage shell holding 6.5 floors of authorized city per floor of land — the gap between what the ground holds and what the rules, as of this winter, finally allow.

## Open Questions

The Registre foncier chain would resolve the sharpest gap: who owned the building in 2013, and the exact date and price of Rester Management's acquisition (2019 per most reporting, though Le Devoir's 2022 "ten years" claim conflicts). The rôle d'évaluation foncière entry would supply the matricule, assessed value and recorded floor area. The Archives de Montréal permit card for 1924 would name the original architect and contractor. The MELCCFP and municipal contaminated-sites registries should be checked against the reported chemical-storage interval. The zone number and grid under 01-277 sit in the arrondissement's PDF annexes. Lovell's Directory, via BAnQ, would date the Docu-Dépôt and Docudata transitions precisely and recover mid-century occupants. Finally, the city council minutes from winter–spring 2026 would confirm whether règlement 25-021 was formally adopted and whether the recommended heritage citation was initiated — the record pulled here ends at the December 19, 2025 OCPM report and the City's stated winter-2026 adoption window.
