The One | 1 Bloor Street West
An 85-storey Foster + Partners tower at Yonge and Bloor, planned as Canada's tallest building. Here is what is actually built, who is finishing it, and what buyers should watch.
The One: what it is, and where it stands
The One is the tower at the southwest corner of Yonge and Bloor, at 1 Bloor Street West. It is planned to rise 85 storeys and 308.6 metres, which would make it the tallest building in Canada when it is finished. Foster + Partners designed it. Sam Mizrahi launched the project, acquired the site in 2014 and famously demolished the Stollerys building over a weekend in 2015.
The build did not go to plan. The project went into receivership on October 18, 2023, at the request of its senior lender, and moved into CCAA proceedings on April 22, 2025. Mizrahi Developments is no longer involved. In May 2025, Tridel was retained as development manager, construction manager and sales manager, and construction has continued under that team.
So when someone asks me about The One today, the honest answer has three parts: yes, it is real and rising; no, you cannot simply buy a suite in it right now; and the story around it matters as much as the architecture. I walk past this site constantly, and I follow the court filings so my clients do not get surprised.
Architecture, specs and what is actually inside
Here is what is confirmed as of my research on November 2, 2026. The tower is 85 storeys and 308.6 metres, designed by Foster + Partners with a braced-frame exoskeleton look that hides nothing structural behind cladding. The building mixes three uses: a multi-storey retail podium at the base, a hotel component, and condominium suites above.
The suite count has shifted with the project’s finances. The original plan held roughly 415 suites. During the receivership, a reconfiguration of the upper floors targeted 503 suites. Tridel’s own project FAQ now states the project is pursuing 476 condominium suites in the 85-storey tower. Until the transition plan is final and the building registers, treat every suite count as provisional.
What I cannot give you yet: a final suite mix, finishes, or floor plans. Tridel has not re-released the project to market as of my research date. Anything an agent quotes you from the old 2017-era sales campaign should be treated as history, not inventory.
What buyers should verify before touching this project
If you are eyeing The One as a pre-construction purchase, the last three years are your due-diligence checklist. Nearly every original purchaser went through a court-approved cancellation of their agreement in 2025; 314 pre-sale agreements were voided with the monitor’s support. Many of those buyers had waited close to a decade. Deposits held in trust were returned, but the appreciation and certainty they thought they had bought were not.
When Tridel re-releases suites, verify before you sign: that the deposit structure is fully protected under Tarion’s rules for pre-construction condo purchases; that the interim occupancy and final registration timelines in your agreement are realistic against the construction schedule; and that the purchase agreement defines what happens if the project changes again. A ten-day cooling-off period applies to pre-construction agreements in Ontario. Use those ten days for a lawyer who reads insolvency-adjacent deals, not just standard resale paperwork.
Watch the status of the hotel and retail components too. Those pieces were still under review by Tridel as of my research. A hotel operator and strong retail tenants support daily life in the building; an unfinished podium is years of hoarding and construction noise around your entrance.
Maintenance fees and carrying costs: what is known
Maintenance fees for The One are unconfirmed and will stay that way until the corporation registers. Any dollar figure you see quoted online for fees at this address is either from the cancelled original campaign or invented. I will not repeat it here.
You can still plan sensibly. Budget as if fees will land at the premium end for the neighbourhood, consistent with a full-service luxury tower: concierge, hotel-level amenities, and the operating costs of a very tall building with substantial common areas. Property taxes will be assessed after registration. If you are comparing The One against a finished building nearby, compare against 102 Bloor West or 1 Yorkville carrying costs, then add a margin for uncertainty.
Exposures and view considerations
At Yonge and Bloor, the view math is unusual. The One is one of the few sites in Toronto where height itself is the view protection. High floors should hold long sightlines: south over the downtown core toward the lake, west toward Yorkville and the Avenue Road hill, north toward Rosedale’s ravine edge.
The real exposures question at this address is what happens around you. Yonge and Bloor is seeing continuous intensification, including taller projects on the east side, so lower and mid floors should be priced and valued with sightline risk, not just current sightlines. That cuts both ways: a floor you buy for the view can lose some of it, which matters on resale. Ask specifically which floors sit above the mechanical and hotel levels before you assume suite numbers mean anything about height.
Selling at The One: what owners and flippers should understand
There is no resale market at The One yet, and there cannot be one until the corporation registers, likely around the 2028 completion window. If you hold an old agreement, the first thing to understand is whether it survived the 2025 cancellations. Most did not. If you still have an active agreement, your assignment rights under it are the only exit you have before registration, and they depend entirely on the contract’s assignment clause.
When a resale market does open, the sellers who do best will have receipts: the Tarion documentation, the final registered floor plan, and a clear story about which campaign they bought in. The building’s insolvency history will be a buyer objection for a while, and the answer is preparation, not deflection.
If you own at the intersection already, in a building like The Maxus at 80 Cumberland, The One matters to you too. It will reset foot traffic, retail energy and construction disruption at Bloor and Yonge for years, on both sides of the street.
Honest pros and cons
Pros. Canada’s proposed tallest tower, by a marquee architect, at the single most connected intersection in the country. Bloor-Yonge station is at the corner, with both Line 1 and Line 2. Yorkville’s retail and the Village of Yorkville Park are steps away. Tridel finishing the project is a meaningful credibility upgrade after the receivership.
Cons. The project has a cancelled-agreement history you cannot ignore. No suite is buyable as of my research date. Fees, mix and final occupancy are unconfirmed. Yonge and Bloor is loud, construction will continue around the base for years, and the retail podium’s anchor tenants are unconfirmed. Anyone who tells you appreciation here is a sure thing is selling you the 2017 brochure.
Buyer and leasing overview at Yonge and Bloor
Until The One registers and its suites come online, buyers who want this exact corner have two practical routes: wait for Tridel’s re-release, with the deposit and timeline protections I described above, or buy in a finished building at the same intersection. For live options right now, browse the One Bloor West condos for sale listings page, which shows whatever is currently on the market in this pocket.
For leasing: nothing at The One will rent until occupancy begins in the 2027 window at the earliest. Investors should underwrite with a late-2020s delivery, not a 2026 one. If rental income near Yorkville is the goal today, the finished buildings along Bloor, Cumberland and Yorkville Avenue are where the actual inventory is, and I would rather show you five real suites than one rendering.
Neighbourhood and transit context
The One sits at the corner that defines Bloor-Yorkville’s eastern edge. Bloor-Yonge station is at the intersection, connecting both of the TTC’s main subway lines. Walk west along Bloor and you are into the Mink Mile’s flagship retail within two blocks. Walk north on Yonge and Rosedale’s ravine edge begins within a few minutes. Ramsden Park sits just south and west. The Village of Yorkville Park, at Cumberland and Bellair, is a short stroll west of the site.
The neighbourhood trade-off is simple and I say it to every client: nowhere in Toronto puts more city at your door, and nowhere asks you to share it with more people. The corner of Yonge and Bloor is the busiest the city gets. If you want Yorkville quiet, look toward the Hazelton and Scollard side.
Frequently asked questions about The One
When will The One at 1 Bloor Street West be completed?
Per Tridel’s project FAQ, interim occupancy is expected to start in Spring 2027, with the building projected to complete in early 2028. The project has a history of delays, so I would treat those dates as Tridel’s current plan, not a promise.
Can I buy a condo in The One right now?
Not as of my research on November 2, 2026. Tridel was retained in May 2025 as development, construction and sales manager, but the project has not been re-released to market. Registering interest with the project’s official sales channel and waiting for the re-launch is the legitimate route. Anyone offering you a suite today should be checked very carefully.
What happened to the people who bought pre-construction suites in The One?
Court proceedings in 2025 approved the cancellation of 314 pre-sale agreements. Purchasers’ deposits held in trust were returned, but their purchase agreements ended. Tridel’s transition process determines how and when suites are offered again. If you were affected, the monitor’s case website at alvarezandmarsal.com and Tridel’s project FAQ are the official sources.
How tall is The One and how many suites will it have?
The plan is 85 storeys and 308.6 metres, which would make it Canada’s tallest building. The suite count has moved: roughly 415 originally, a court-documented reconfiguration targeted 503, and Tridel’s FAQ says the project is currently pursuing 476 suites. The final number lands at registration.
Is Mizrahi Developments still building The One?
No. The project went into receivership in October 2023 and CCAA proceedings in April 2025, and Mizrahi Developments is no longer involved in development or construction. Tridel leads the project as development manager, construction manager and sales manager, with FAAN Advisors Group as Chief Restructuring Officer.
What will the hotel and retail podium at The One contain?
Unconfirmed. The design includes a multi-storey retail podium and a hotel component, but as of my research Tridel was still reviewing plans for both, including anchor tenants and the hotel operator. Treat any brand names you hear as rumour until the project announces them.
