Multiplex Investing in Scarborough: Why 2026 Is the Moment

If you are an investor weighing where to build a multiplex in the GTA right now, the real question underneath that search is simple: where does the math still work? Central Toronto land has climbed to a point where the spread between what you pay for a lot and what the finished building is worth has narrowed considerably. Scarborough is where that spread is widest in 2026 — lower land basis, genuinely deep rental demand, and major transit investment landing over the next few years. At Metrohomes, we have been designing and building across the GTA since 1988, and Scarborough is one of the most compelling multiplex investing opportunities we are tracking today. Here is why, and how to evaluate a specific lot before you commit a dollar.

Why Scarborough, why 2026

Two forces have come together at the same moment, and that timing is what makes 2026 worth paying attention to. The first is regulatory. Ontario's Bill 23 and Toronto's updated zoning bylaws now permit up to four residential units as-of-right on most residential lots across the city — no rezoning, no lengthy Committee of Adjustment battle for the base entitlement. Scarborough, which was historically zoned almost entirely for single detached homes, is one of the biggest beneficiaries of that shift. Thousands of bungalow lots that could only ever hold one family can now legally hold three or four units. We cover the full regulatory picture in our explainer on Ontario's multiplex zoning under Bill 23.

The second force is infrastructure. Scarborough is in the middle of the largest wave of transit investment in its history — the Eglinton Crosstown extension, the Scarborough Subway Extension replacing the old RT line, and the broader network of bus rapid transit and GO improvements feeding the area. Transit drives rental demand and, over time, land value. The investors who do well are usually the ones who buy before the line opens, not after. When you combine as-of-right fourplex permissions with a district that is being knit into the rapid transit network, you get a window where the entry price still reflects the old Scarborough and the income potential reflects the new one. That gap is the opportunity.

The Scarborough advantage: lower land basis, deep rental demand

Every multiplex pro forma comes down to three numbers: what you pay to acquire the lot, what it costs to build, and what the finished units rent for. Construction costs are roughly the same whether you build in Scarborough or in the Annex — a fourplex framed to the Ontario Building Code costs what it costs. What changes dramatically across the city is the land. A teardown-ready lot in central Toronto often runs well past $1.5 million; in much of Scarborough, suitable lots with existing bungalows can still be found in the $700,000 to $1 million range. That lower land basis is the single biggest lever in the entire investment, because it lowers your total project cost without touching the rent line.

On the demand side, Scarborough is not a speculative bet — it is one of the most consistently tenanted parts of the GTA. It is home to a large, diverse population, multiple post-secondary campuses including the University of Toronto Scarborough and Centennial College, major employment hubs, and the hospitals and institutions that anchor stable, long-term tenancies. Toronto's overall rental vacancy rate has sat below two per cent for years, and Scarborough's family-sized units in particular see strong, durable demand. Rents here run lower than central Toronto, but the lower land basis more than compensates — and you are renting into a market with a deep tenant pool rather than fighting over a thin slice of high-income renters. You can pull the real demographic and rental picture for any specific Scarborough address through our free Neighbourhood Report, which shows who lives in the area, what units rent for, and where the growth zones sit.

Where in Scarborough: neighbourhoods worth a look

Scarborough is large and far from uniform, so the right move is to narrow to the pockets where the fundamentals line up. Wexford-Maryvale is one we know well — it sits near major arterials and the Eglinton corridor, with a stock of mid-century bungalows on lots that are well suited to triplex and fourplex configurations. It offers some of the most workable entry pricing in the area paired with steady family-rental demand, which is exactly the combination a multiplex investor is looking for.

Birchcliffe-Cliffside along the southern lakeshore edge of Scarborough has been quietly gentrifying for years. Its proximity to the Bluffs, the GO line into Union, and an increasingly walkable Kingston Road strip have pushed both values and rents upward, and it tends to attract quality, longer-term tenants. Lots here carry a premium over the inland neighbourhoods, but the achievable rents rise to match. Tam O'Shanter-Sullivan to the north is another solid candidate — a settled, transit-served residential district with a deep pool of family tenants and the kind of generous lot frontages that make four-unit designs work without fighting the zoning envelope at every turn.

These are starting points, not a shortlist to buy blindly. The defining feature of multiplex investing is that the lot is the asset — two properties on the same street can produce very different buildings depending on frontage, depth, lot coverage limits, and rear access.

Proof on the ground: our Wexford triplex (in progress)

We do not talk about Scarborough multiplexes in the abstract — we are building one right now. Our Wexford triplex is a roughly 4,200-square-foot, three-unit building currently underway in the heart of Scarborough. It is a working example of exactly the thesis in this article: a Scarborough lot with a favourable land basis, a three-unit design that fits the as-of-right envelope, and a location with the kind of steady family-rental demand that makes a multiplex investment durable rather than speculative.

Because the project is underway and not yet complete, we are not going to quote you a finished rent roll or a return figure — that would be guesswork, and we do not do guesswork. What the Wexford project demonstrates is process and feasibility: it is proof that the configuration works on a real Scarborough lot, designed and permitted to current code. You can see it alongside the rest of our active and completed work on our projects page. Seeing a real building take shape on a real Scarborough lot is the best antidote to the abstraction that derails a lot of first-time multiplex investors.

Running the numbers: from lot check to pro forma

A disciplined multiplex investor works in two stages. The first is the lot check — confirming what the property can physically and legally support before you ever build a financial model. Our free Property Assessment does exactly this: enter a Scarborough address and it analyzes the lot dimensions, zoning, height limits, and buildable envelope to show you what is realistic on that specific parcel, whether that is a duplex, a triplex, or a fourplex. There is no point modelling income on four units if the lot's frontage and setbacks only support three. The lot check tells you which configuration you are actually underwriting.

Once you know what is buildable, the second stage is the pro forma — and this is where you put your own assumptions in, not ours. Our multiplex ROI calculator lets you enter your land cost, construction budget, expected rents, vacancy allowance, and financing terms, then returns the metrics that matter to a lender and to you: net operating income, cap rate, cash-on-cash return, and debt service coverage ratio. Every figure it produces is driven by the numbers you supply, so it is a framework for stress-testing a deal rather than a quote from us. If you want to understand the difference between a two-unit and a four-unit return on the same lot, our breakdown of duplex vs triplex vs fourplex walks through how the income and cost curves diverge as you add units.

A note on how the math tends to behave in Scarborough specifically: because the land basis is lower, the incremental dollar you spend adding a third or fourth unit works harder here than it does on an expensive central lot. You are spreading a smaller acquisition cost across more income-producing units. That is why so many of the strongest Scarborough deals we see are triplexes and fourplexes rather than duplexes — the configuration that maximizes units on a low-basis lot is usually the one where the cash flow and the financing line up best. For the deeper investor framework behind all of this — NOI, cap rate, the rental math, and how lenders read a multiplex deal — our Multiplex Investor Guide is the most thorough resource we publish.

Budgeting the buy: land transfer tax & financing realities

Two costs catch first-time multiplex investors off guard, and both are easy to plan for once you see them clearly. The first is land transfer tax. In Toronto you pay it twice — once to Ontario and once to the City — and it is calculated on the purchase price of the lot you acquire, not on the finished building. On a $900,000 Scarborough lot that is a meaningful five-figure closing cost that needs to sit in your budget from day one. As an investor buying a property you will not occupy, you also will not qualify for the first-time buyer rebates that apply to a principal residence. Our land transfer tax calculator gives you the exact combined Ontario and Toronto figure for any purchase price, including the graduated luxury tiers that apply above two million dollars. We unpack those upper tiers in detail in our guide to the 2026 Toronto land transfer tax changes.

The second is financing structure. Lenders evaluate a multiplex on its projected rental income and completed value, not just on your personal qualification, and they typically finance a portion of the land purchase and a larger portion of construction costs provided the pro forma cash flow supports the debt. A four-unit building with four tenants is a more diversified — and therefore more financeable — income stream than a single rental, because one vacancy does not sink the whole deal. CMHC's MLI Select program in particular rewards purpose-built rental and energy-efficient multiplex projects with favourable terms for borrowers who can hit its minimum debt service coverage thresholds. The practical takeaway is to model your financing early, because the loan-to-value ratio a lender will offer directly determines how much equity you need to bring. If you would rather work through acquisition, financing, and structuring with a person rather than a calculator, our real estate and investment team does exactly that.

Build it right: why design-build de-risks a Scarborough multiplex

Land that is genuinely affordable is only an advantage if the building gets delivered on budget and on code — and a multiplex is a materially more demanding build than a single-family home. Three or four units bring far more rigorous requirements for fire separation, sound transmission between units, multiple means of egress, and mechanical systems sized for several households. Get any of those wrong in design and you discover it during construction or, worse, during inspection, where it costs real money and real time to fix. This is precisely where the design-build model earns its keep: one team carries the project from lot evaluation and feasibility through design, permitting, and construction, so the person who designs the fire separation is accountable for the person who builds it. We explain why that single line of accountability matters in our comparison of design-build versus hiring a general contractor.

Permitting is the other place design-build de-risks a Scarborough multiplex. As-of-right zoning gets you the entitlement, but you still need a complete, code-compliant permit package to break ground, and incomplete applications are the single most common cause of delay. We have submitted hundreds of permit applications across the GTA and we know what Toronto's plan examiners are looking for, which keeps multiplex projects moving through review without the revision cycles that quietly add months to a schedule. For investors who want to understand the full path from raw lot to finished, tenanted building, our companion pillar on how to build a multiplex in Toronto in 2026 lays out the entire process step by step.

Scarborough's combination of a lower land basis, deep and durable rental demand, and a once-in-a-generation wave of transit investment is exactly the kind of alignment that does not stay quiet for long. The disciplined way to act on it is in order: pull a Neighbourhood Report on the addresses you are considering, run the lot through our free Property Assessment to confirm what it can actually support, stress-test the deal in the multiplex ROI calculator, and then talk to a team that has built these on real Scarborough lots. At Metrohomes, we design and build multiplexes of every configuration — including right here in Scarborough — and we would be glad to walk a specific lot through with you before you write an offer. The best multiplex investment is always the one where the numbers work, the lot supports the building, and the team can deliver it. In Scarborough in 2026, more of those line up than almost anywhere else in the city.
