The honest question for Canadian investors
Canadian rental investing is, mathematically, an appreciation bet. With CBRE's national high-rise Class A multifamily cap rate at 4.51% in Q1 2026 (Toronto 3.85–4.75%, Vancouver 3.50–4.00%), a 20%-down investment mortgage usually produces a monthly deficit. Investors accept that deficit because they expect the property's value to rise. Fine — but that reframes the question entirely: is the appreciation bet better than just investing the down payment and the monthly shortfall somewhere else?
Leverage is the reason it can still win. Your 20% down controls 100% of the asset, so appreciation compounds on the whole property value rather than only your contribution. Add tenant-funded mortgage paydown and property can beat an unlevered alternative despite cash-flowing negative. But the same leverage cuts both ways, and Canada's rules tighten the vice: a 20% minimum down payment with no CMHC insurance available for pure investment properties means a lot of capital committed before the bet even starts.
This comparison stays symmetric — the alternative path receives not just your down payment but every dollar you'd have spent covering the property's monthly shortfall, compounding at the same rate. Figures are pre-tax; on sale, capital gains apply at the 50% inclusion rate plus recapture of any CCA claimed. See the rental property ROI calculator for the full property view and the capital gains calculator for the exit.
No official Canadian source publishes a current cap-rate or total-return series you can plug into this comparison as fact — treat your appreciation and alternative-return inputs as assumptions you're choosing, not numbers this page can hand you. What IS officially published: the capital gains inclusion rate stays at one-half (the proposed increase to two-thirds was cancelled), any CCA you claimed is added back to income as recapture on sale per CRA's rental income guide, and every uninsured mortgage — which covers most investment-property purchases — must qualify at OSFI's minimum qualifying rate, not your contract rate.
Why this page can't hand you a cap rate or return assumption
A fair rent-vs-invest comparison needs an honest appreciation assumption and an honest alternative-return assumption, and this registry could not verify a current, citable Canadian cap-rate or total-return series to supply either one. The one candidate source found for city-level cap rates returned a Cloudflare block on every fetch attempt this session, so no per-city or national cap-rate figure from it can be published here as a sourced fact. If you've seen a specific cap-rate percentage quoted elsewhere for your market, verify it against a source you can actually open before treating it as ground truth — don't let this page's absence of a number substitute for your own confirmation.
What you can ground your rent input in is CMHC's own survey data. CMHC's October 2025 Rental Market Survey for Toronto shows average purpose-built rent rising from C$1,850 to C$1,913 year-over-year (3.4%), while vacancy rose from 2.5% to 3.0% over the same period — rents still climbing, but against loosening supply. Statistics Canada's asking-versus-paid rent series adds a second data point: Toronto's Q2 2026 average asking rent for a 2-bedroom (C$2,650) ran well above the average paid rent on existing leases (C$2,160) — a reminder that your rent-growth assumption should be anchored to achievable turnover rent, not the highest asking price in the neighbourhood.
The financing constraint behind the down payment
Why does a Canadian rental typically need 20% down rather than the 5% an owner-occupied purchase allows? Under OSFI's Guideline B-20, high-ratio mortgages — loan-to-value above 80% — must be insured, and CMHC's homeownership insurance program is built for owner-occupied purchases, not pure investment properties. That combination pushes a straight rental purchase to a conventional, uninsured structure at 80% LTV or lower, which is the practical origin of the 20% minimum this comparison assumes.
That uninsured mortgage then has to clear OSFI's minimum qualifying rate: the greater of your contract rate plus 2%, or a 5.25% floor. That's the rate a lender tests your application against, and it's worth running your own debt-service math at that stress-tested rate — separately from the contract rate you enter into this calculator's monthly cash-flow projection — so the "out of pocket" side of the comparison reflects what qualifying actually required, not just what you'll eventually pay.
For a sense of where actual borrowing costs sit, the Bank of Canada's own rate data shows the chartered-bank prime lending rate at 4.45% as of mid-September 2026 — each institution sets its own prime, influenced by but not identical to the Bank of Canada's policy rate. Your actual contract rate will sit at some spread to that, which is the number that determines whether the property path or the alternative-investment path shows a larger out-of-pocket contribution during the hold.
The exit: what actually gets taxed
Both paths in this comparison end with a number, and only one of them faces a specific, sourced tax treatment on exit. If you sell the property, the gain is a capital gain (assuming you're not caught by the 365-day property flipping rule), and the government confirmed the capital gains inclusion rate remains at one-half rather than rising to two-thirds as previously proposed — so only half of your gain is added to taxable income. But if you claimed capital cost allowance on the building during the hold, CRA's rental income guide requires that CCA to be added back to income as a recapture (if proceeds exceed the building's remaining undepreciated capital cost) before the capital-gains treatment applies to what's left — a real, separately-taxed cost of the deductions you took along the way, and one this calculator's pre-tax figures don't model.
What CCA actually does to your cash flow during the hold, not just at exit
The exit-tax section above covers CCA recapture on sale, but the deduction only helps you during the hold if you understand how CRA lets you claim it. Most rental buildings fall into CCA Class 1, depreciated at a 4% declining-balance rate — a small annual deduction against rental income relative to the building's value, not the accelerated write-off some investors assume. In the year you acquire the property, the half-year rule limits your first CCA claim to half of that 4%, so year one shelters even less income than year two onward. And CCA works the other way at a loss, too: if you sell for less than the building's remaining undepreciated capital cost, CRA has you deduct a terminal loss from income rather than add a recapture — the mirror case to the recapture math already covered, worth knowing if your exit scenario is a downturn rather than a gain.
Methodology
This addition does not alter the calculator's own ending-wealth math (property path vs. alternative-investment path, both compounding at your stated alternative return). It supplies the sourced inputs the comparison depends on — CMHC's and StatCan's published rent data, OSFI's qualifying-rate rule, and CRA's/the federal government's exit-tax rules — current as of 2026-09-21, and states plainly where no official Canadian return-series source exists rather than estimating one.

Why the Canadian version is an appreciation bet
| Factor | Effect |
|---|---|
| Cap rates ~3.5–4.5% (Toronto/Vancouver) | Rent rarely covers the mortgage |
| 20% minimum down, no CMHC for investment | Large capital committed up front |
| Monthly shortfall | Cash you must fund — or invest elsewhere |
| Appreciation + paydown | Where the return has to come from |
The alternative path here receives your down payment AND every dollar you'd have spent covering the shortfall, compounding at the same rate. Pre-tax.
Frequently asked questions
How is this different from a normal rent vs buy calculator?
A consumer rent-vs-buy calculator asks whether you should buy the home you live in instead of renting it. This is the investor version: it asks whether buying a rental property to let out beats simply investing the same capital somewhere else. The question isn't housing — it's what your money should be doing. That makes the opportunity cost of your down payment the central variable rather than an afterthought.
What is the opportunity cost of a down payment?
It's the return your down payment would have earned if you hadn't tied it up in a property. A rental that returns 6% a year isn't obviously good or bad in isolation — it depends entirely on what else that capital could have done. If an alternative investment would have returned 8%, the property is destroying value relative to the alternative despite showing a positive return. Most rental calculators ignore this comparison entirely.
Why does property often win despite low rental yields?
Leverage. When you put 25% down, your appreciation compounds on the full property value, not just the capital you contributed — so 3% appreciation on the whole asset is roughly 12% on your down payment before costs. Add tenant-funded mortgage paydown, which quietly converts debt into equity, and property can beat an unlevered alternative even with modest yields. The flip side is that leverage magnifies losses just as efficiently.
How does this comparison stay fair?
Both paths compound at the same alternative rate. The property path reinvests each year's positive cash flow at that rate; the alternative path receives not just the initial capital but also any money you'd have spent covering the property's negative cash flow. Without that symmetry the comparison would quietly flatter one side — a common flaw in property-versus-market arguments.
Why does the hold period change the answer so much?
Real estate carries heavy transaction costs — several percent to buy and several more to sell — which punish short holds badly. An index fund has almost none. But over a long hold, leverage, mortgage paydown, and rent growth compound in property's favour while those one-time costs amortise away. The answer frequently flips somewhere in the middle, which is why it's worth testing several horizons rather than trusting a single number.
Does this include taxes?
No — it's a pre-tax comparison. Tax treatment varies enormously by investor and jurisdiction: depreciation, how rental losses offset other income, capital gains on sale, and the tax on investment gains all depend on personal circumstances. Modelling it generically would create false precision. Use the dedicated depreciation and capital-gains tools for the tax layer, and speak to a professional.
