Windsor, Ontario
Windsor is a city of two kinds of very large owner. Five per cent of its land is federal — 711 hectares of it the Windsor Port Authority's and 74 hectares the Crown land under the Canadian end of the Gordie Howe bridge — and most of the rest of the consequential ground is industrial: Stellantis's 177-acre, 4.4-million-square-foot assembly plant and LG Energy Solution's 4.25-million-square-foot battery plant. The one border crossing that is not public is privately held through The Canadian Transit Company. Ontario charges $37.10 a parcel to read the register and publishes no roll and no prices, which is why the city's best-known building, Caesars Windsor, carries a blank here.

Can you find out who owns it?
Ontario's land registry is the official record of ownership and it is public but not open: ServiceOntario states it "contains the official records of property ownership and other legal interests such as mortgages, transfers and leases" and "covers more than 7.4 million parcels of land in the province", that the services "are only available online", and that on OnLand "You can do a self-search for a fee" — $37.10 per parcel register under the bulletin effective 2 November 2026, with no bulk extract at any price and Teraview restricted to licensed users. MPAC publishes no assessment roll and the 2026 tax year still runs on 1 January 2016 values; Ontario publishes no price-paid file, so a Windsor sale price exists only on the individual registered transfer. What makes Windsor legible at all is that its biggest holders are either federal — and therefore listed, with land areas, in the open Directory of Federal Real Property — or publicly listed companies that describe their own plants in filings and fact sheets. Where neither applies, the answer costs $37.10 and this record says so.

The marquee buildings
The towers that set the tone of the core, and who holds them. A price is the price a document states, on the date it states — not an estimate of what the building is worth now.
| Building | Use | Owner | Owner type | Last price paid |
|---|---|---|---|---|
| Windsor Assembly Plant 2199 Chrysler Centre, Windsor 4.4 million sq ft of floor space on 177 acres |
Industrial | Stellantis N.V. Stellantis North America's own plant fact sheet for Windsor Assembly Plant, 2199 Chrysler Centre, Windsor, Ontario: "Floor Space: 4.4 million square feet. Acreage: 177 acres." It records the facility as built in 1928, names Unifor Locals 195, 444 and 1498, and lists current products as the Chrysler Pacifica, Chrysler Grand Caravan (Canadian market only), Dodge Charger Daytona and Dodge Charger SIXPACK. The sheet states that "on May 2, 2022, a $3.6 billion CAD ($2.8 billion USD) investment was announced to transform" the Windsor and Brampton plants. This is the company's own fact sheet for its own plant; it is not a register entry and states no title. |
Public company | —A |
| NextStar Energy battery plant EC Row Avenue at Banwell Road, Windsor 4.25 million sq ft |
Industrial | NextStar Energy Inc. wholly owned by LG Energy Solution after Stellantis sold its 49 per cent stake CBC Windsor, reporting the plant's grand opening on 5 March 2026, quotes Ontario's premier on "this 4.25-million square foot facility", records that "the provincial and federal government have pledged up to $16 billion in subsidies to NextStar", that "it was originally a joint venture between automaker Stellantis and LG Energy Solution" but "Stellantis recently sold its 49 per cent stake to LG", and that roughly 1,300 people had been hired with another 1,200 expected. NextStar's own site describes the company as "Powered by the strength and expertise of LG Energy Solution". No land area is stated by either source, so none is claimed. |

| Devonshire Mall 3100 Howard Ave, Windsor 669,200 sq ft GLA on approximately 73 acres, 159 tenants |
Retail | Primaris Real Estate Investment Trust 100% Primaris REIT's Annual Information Form for the year ended 31 December 2023 lists Devonshire Mall, Windsor, Ontario, segment "Enclosed", ownership share 100 per cent, 669.2 thousand sq ft of GLA and 159 tenants. Its description calls it "a super-regional mall in Windsor, Ontario located proximate to the United States border", "initially developed in 1970, is situated on approximately 73 acres and was last renovated in 2019", with CRU sales productivity of $687 per square foot. The AIF defines the "HOOPP Properties" as eight properties "indirectly acquired by Primaris from HOOPP on December 31, 2021", appraised together at about $0.8 billion. |

| Ambassador Bridge — the Canadian half Huron Church Road at the Detroit River, Windsor |
Institutional | The Canadian Transit Company CBC Windsor, 11 February 2026, reports Windsor's dealings with "Moroun and the Canadian Transit Company" over "long vacant properties in the area around the Windsor side of the bridge", states that the "Moroun family has owned the Ambassador Bridge since 1979", names "Matthew Moroun, the Detroit-based owner of the Ambassador Bridge", and quotes Mayor Drew Dilkens: "It is unique and it speaks to the unique circumstance of having an international crossing in private hands." The Canadian Transit Company is named as the owner because it is the entity the City deals with in that reporting; the family is context because the cited outlet identifies it. No land area, floor area or price is stated. |

| Gordie Howe International Bridge — the Canadian port of entry lands Between Broadway and Chappus Streets, fronting the Detroit River, Windsor 74.34 hectares (184 acres) |
Institutional | Government of Canada (Housing, Infrastructure and Communities Canada) The Directory of Federal Real Property records "Windsor-Detroit River lands", described in the dataset as "Between Broadway and Chappus Streets, fronting the Detroit River", custodian Housing, Infrastructure and Communities Canada, interest type "Crown Owned", use "Managed Land", 74.34 ha in Windsor. The Windsor-Detroit Bridge Authority's own fact sheet states WDBA "is a not-for-profit Canadian Crown corporation which reports to Parliament", created in 2012 and "wholly owned by the Government of Canada but ... structured like a private company", to procure and oversee the bridge through a P3. The dataset's custodian is the infrastructure department rather than WDBA. |

| Port of Windsor Windsor waterfront, including Russell Street Terminals and 95 Mill Street 711.15 hectares (1,757 acres) across six Crown-owned properties |
Industrial | Windsor Port Authority The Directory of Federal Real Property records six Crown-owned Windsor Port Authority properties totalling 711.15 ha: the main holding, "Windsor Port Authority", at 675.07 ha, "Russell Street Terminals" at 31.04 ha, the "Brock Street Property" at 1.42 ha, and a 1.90 ha site at 95 Mill Street recorded as "Department of National Defense Navy" with a 6,000 m² building. The port authority is flagged in the dataset as a Crown corporation custodian. This is the largest landholding in Windsor established from any open source — 4.87 per cent of the city's land area on its own. |

| Government of Canada Building, Windsor 441 University Avenue West, Windsor 4,668 m² (50,250 sq ft) on 0.43 hectares |
Office | Government of Canada (Public Services and Procurement Canada) Directory of Federal Real Property: "GC Site - Windsor", 441 University Avenue West, PSPC, interest type "Crown Owned", primary use "Office". It is the only federal office building Canada owns in Windsor; PSPC leases seven more, including 4,625 m² at 2500 Ouellette Avenue, 2,904 m² at 400 City Hall Square East, 2,152 m² at 1250 Walker Road, 1,836 m² at 100 Ouellette Avenue and 464 m² at 1 Riverside Drive West. Fifteen of Windsor's 32 federal properties are Crown-owned; the other seventeen are leases, licences or occupancies without an interest. |

| Caesars Windsor 377 Riverside Dr E, Windsor 101,600 sq ft of casino space, 1,620 slot machines, 80 table games, 760 hotel rooms |
Hotel | Not established a paid title search would answer it The best-known building in Windsor, and a blank on purpose. Caesars Entertainment's own Form 10-K for the year ended 31 December 2025 lists Caesars Windsor under its "Managed and Branded Segment — Managed" and footnotes it: "In May 2025, the Ontario Lottery and Gaming Corporation selected Caesars to assume the full operation of Caesars Windsor, which is expected to occur in March 2026, at which time the property will move into our Regional segment as a Leased property." The operator's own SEC filing therefore establishes that the operator is not the owner. No OLG or provincial document stating title was opened — every OLG corporate path tried returned a 404 — so no owner is inferred. |

The core land
The most valuable ground in the city, and what the public record says about it.
Windsor is a small, dense municipality — 146 square kilometres — with two enormous industrial plants, two international crossings and a port, which means an unusually high share of its consequential ground has an owner that is either a Crown body listed in an open federal dataset or a public company that describes its own site in a filing. The Directory of Federal Real Property was downloaded in full and parsed parcel by parcel for this record and attributed to municipalities by the dataset's own Municipality and Metro Area fields; land-area shares are computed against the 2021 Census. What remains unanswerable is the ordinary commercial city: no Windsor office building, no apartment block and no assessed value appears in any open source.
Largest landowner in WindsorWindsor Port Authority — 711.15 ha (4.87% of the city)
Directory of Federal Real Property, dataset dated 21–22 November 2025, parsed 3 October 2026, against Windsor's land area of 146.02 km² from Statistics Canada table 98-10-0002 (2021 Census). Six Crown-owned properties, the largest 675.07 ha.
All federal real property in Windsor32 properties, 814.68 ha (5.58% of the city), 47,765 m² of floor space in 23 buildings
Same parse: 15 Crown Owned (805.38 ha, 28,700 m², 9 buildings), the rest leases or licences. Custodians of the Crown-owned land: Windsor Port Authority 711.15 ha, Housing, Infrastructure and Communities Canada 74.34 ha (the Gordie Howe bridge lands), Parks Canada 13.60 ha (a proposed national urban park), Canada Post 4.25 ha, RCMP 0.89 ha, PSPC 0.43 ha, National Defence 0.42 ha and the Canadian Food Inspection Agency 0.30 ha.
The two biggest private industrial sites4.4M sq ft on 177 acres (Stellantis) and 4.25M sq ft (NextStar Energy)
Stellantis North America's own Windsor Assembly Plant fact sheet gives 4.4 million square feet of floor space on 177 acres, built 1928. CBC Windsor, at the 5 March 2026 grand opening, quotes the premier on NextStar's "4.25-million square foot facility" and records up to $16 billion of pledged provincial and federal subsidy. Together the two plants carry more floor space than every federal building in the city by a factor of roughly 170.
One of the two international crossings is privately heldThe Canadian Transit Company owns the Canadian half of the Ambassador Bridge; the Crown owns 74.34 ha under the Canadian end of the Gordie Howe
CBC Windsor, February 2026, quoting Mayor Drew Dilkens: "It is unique and it speaks to the unique circumstance of having an international crossing in private hands." The same report states the Moroun family has owned the bridge since 1979. The Gordie Howe lands are recorded as Crown Owned in the federal directory, with the Windsor-Detroit Bridge Authority — "wholly owned by the Government of Canada" — created in 2012 to procure and oversee the crossing.
Highest assessed parcel / core assessed totalnot published
MPAC's Assessment Cycle page, read 3 October 2026: "Property assessments for the 2026 property tax year will continue to be based on fully phased-in January 1, 2016 current values." Values are reachable only through three login-only products and aboutmyproperty.ca redirects a script to a CAPTCHA. citywindsor.ca returned "Not Found" at every finance path tried, so no municipal assessment base was obtained either.
Provincial housing target and progress13,000 homes by 2031; 3,143 since 2022; 2,306 in 2024 against a 1,083 target (212.93%)
Ontario's housing supply progress, January–December 2024, data.ontario.ca, Open Government Licence – Ontario. Status: "Exceeded" — Windsor was the only one of the five Ontario cities in this batch to beat its 2024 target, and it beat it by more than double. Global News reported in 2026, from a provincial briefing note obtained under freedom-of-information law, that Windsor then reached only 47 per cent of its 2025 target.

Who builds the houses
New-home building in this market: the volume, and the firms behind it. Ownership of a builder matters as much as its volume — a private-equity platform and a family firm behave differently.
Windsor has the thinnest homebuilder register of the five cities in this batch, and that is itself the finding. The Home Construction Regulatory Authority's Ontario Builder Directory publishes each licensee's "Total Possessions" — freehold and condominium homes actually occupied by a buyer — and the largest Windsor-registered umbrella in it records 610, against 35,888 for Mattamy province-wide and 3,371 for the largest Hamilton firm. Windsor's volume comes instead from a mix of small local builders below the threshold of visibility and from the provincial players, and the city's 2024 result — 2,306 units of progress against a 1,083 target, the only "Exceeded" in this batch — is not attributable to any one firm from any open source. The usual Ontario caveats apply: the counts are cumulative and province-wide, not annual Windsor starts, and builders incorporate a company per project so only the umbrella account is usable. Purpose-built rental is not warranty-enrolled and so is invisible here entirely.
| Name | Type | Total possessions (cumulative, Ontario) |
|---|---|---|
| Valente Development HCRA umbrella 12520665, 2985 Dougall Avenue, Windsor: 348 freehold + 262 condominium, 4 chargeable conciliations and $81,972 in claims. The largest Windsor-headquartered builder umbrella in the directory. Two further Valente licences appear separately — Valente Construction Limited of Tecumseh, licensed 11 May 1977 with 3 possessions, and S&S Valente Investments Inc. of Lakeshore — a textbook illustration of why the umbrella is the only usable level in this dataset. |
Family / private | 610A |
| Amico Housing HCRA umbrella 11252, 2199 Blackacre Drive, Oldcastle (Windsor area): 26 freehold + 118 condominium, zero chargeable conciliations and no claims. Amico is better known in Windsor-Essex as an infrastructure contractor. |
Family / private | 144A |
| Mattamy Homes HCRA umbrella 3337, 66 Wellington Street West, Toronto: 27,077 freehold + 8,811 condominium, 14 chargeable conciliations. Included for scale, not because the directory attributes any of it to Windsor — it does not publish a municipal split, and this is the comparison that makes the Windsor numbers legible. |
Family / private | 35,888 (province-wide)A |
| Rob Piroli Construction Inc. HCRA standalone licence, 1500 Ouellette Ave Unit 201, Windsor, licensed 20 October 1994: 0 freehold, 0 condominium, 1 chargeable conciliation, and the licence is not in "Licensed" status. Recorded here because it is one of only a handful of Windsor-registered builders the directory holds at all. |

| City of Windsor — all builders Ontario's housing supply progress, January–December 2024: Windsor recorded 2,306 units of housing progress against a 2024 target of 1,083 (212.93%, status "Exceeded"), and 3,143 since 2022 against a ten-year target of 13,000. The province counts housing starts, additional residential units, long-term-care beds, licensed congregate retirement suites and postsecondary student beds, so a strong year can reflect institutional beds as much as houses. Global News reported in 2026 that Windsor reached 47 per cent of its 2025 target. |

Commercial landlords
The commercial side, counted separately from housing: who holds the office, retail and industrial floor area.
Windsor's commercial property is dominated by things that are not conventionally commercial: a port, two border crossings, two vast manufacturing plants and a single large enclosed mall owned by a listed REIT. There is no Windsor office landlord in this record, because no document naming one could be opened — the federal government leases seven office buildings in the city and the federal dataset names the tenant in each case and the landlord in none.
| Name | Type | Floor area / land / assets |
|---|---|---|
| Windsor Port Authority Directory of Federal Real Property, parsed 3 October 2026: the main 675.07 ha holding plus Russell Street Terminals (31.04 ha), the Brock Street Property (1.42 ha) and 95 Mill Street (1.90 ha, with a 6,000 m² building recorded as "Department of National Defense Navy").

Looked for and not found
Claims this page would have made if a source could be opened. They are left out rather than guessed.
- Who holds title to the Caesars Windsor complex. Caesars Entertainment's own Form 10-K establishes that it does not — the property is "Managed" and moves to the Regional segment "as a Leased property" in March 2026 — and CBC establishes that the Ontario Lottery and Gaming Corporation ran the twenty-year operator procurement. No OLG or provincial document stating title was opened: about.olg.ca returns the same 404 body at every corporate path tried. The record therefore names no owner rather than inferring one.
- The site area of the NextStar Energy battery plant. Search results give figures between 213 and 230 acres; neither CBC nor the company's own site states one, so none is carried.
- The price paid for Devonshire Mall. It was acquired as one of eight HOOPP Properties appraised together at about $0.8 billion on 31 December 2021; Primaris's AIF breaks out no price for the individual mall.
- The registered owner of any private office building in Windsor, including 2500 Ouellette Avenue, 1250 Walker Road, 100 Ouellette Avenue and 1 Riverside Drive West — all four confirmed as federal leases in the Directory of Federal Real Property, with the tenant named and the landlord not. The parcel register costs $37.10 per PIN.
- Farhi Holdings Corporation's Windsor and Essex County holdings. The Globe and Mail's October 2024 mapping of the company's portfolio counted 14 properties in Essex County, which contains Windsor, but that count was not re-opened for this record and no Windsor-boundary figure exists.
- Any assessed value for any Windsor parcel, and therefore any 'highest assessed parcel' or core assessed total. MPAC publishes no roll and its lookup is CAPTCHA-gated.
- Any per-sale price with an address anywhere in Ontario. Consideration appears on the registered transfer instrument only, per parcel, at the fees in s2 — which is why this record carries no Windsor transaction price at all.
- The City of Windsor's own total taxable assessment and its city-owned property inventory. citywindsor.ca returned "Not Found" at every path tried.
- The owner of the Hiram Walker & Sons distillery complex, one of the largest industrial landholdings on the Windsor riverfront, and of the Windsor Star building — two obvious candidates for this list for which no opened source named an owner.
- Whether any sitting member of Windsor City Council holds property relevant to a council decision. No conflict-of-interest registry was reachable on citywindsor.ca, nothing was established and nothing is claimed.
