I get some version of the same question from almost every investor I talk to right now: does the math still work? Rates have been parked in the same spot for months, headlines swing between "buyer's market" and "still too expensive," and it's genuinely hard to tell where the real opportunity is versus where you're just buying into someone else's stale pricing. So I want to walk through what cap rates and cash flow actually look like across the region right now - not the national headline number, but what changes as you move from downtown Toronto out through the GTA to Hamilton, Halton, and Niagara.

The Rate Backdrop Hasn't Moved, and That's the Point

The Bank of Canada has held its overnight rate at 2.25 percent through six straight decisions, most recently on July 15. The next announcement is September 2, and bond markets are pricing in a seventh hold as the overwhelming likelihood. For anyone underwriting a purchase, that's actually useful information - financing costs aren't the variable right now. If a deal doesn't pencil at today's rates, waiting another six weeks for a cut that isn't coming won't fix it. The variable that's actually moving is price, and it's moving differently depending on the asset and the postal code.

Where GTA Multifamily Cap Rates Actually Sit

On institutional-grade apartment product across the GTA, cap rates averaged 4.64 percent in the second quarter, up just 7 basis points year-over-year and essentially flat against where 2025 ended. That's after climbing through the first quarter, so the more accurate read is that yields have leveled off rather than kept expanding. Sales volume was down 8.3 percent to $418 million, but the number of trades actually increased 5.6 percent - smaller deals moving, bigger ones sitting. Average price per suite rose to roughly $307,600, propped up by a handful of newer, higher-quality buildings changing hands. Multifamily remains the tightest cap rate of any asset class in the country, sub-5 percent almost everywhere, which tells you where institutional capital still wants to be even in a slower market.

Hamilton and Halton: Small Multi-Res Runs on Different Math

Here's something worth knowing if you're comparing what you read about GTA cap rates to what you're actually being offered on a Hamilton duplex or a Burlington triplex: Hamilton doesn't have a published institutional cap rate series the way Toronto does. Appraisers and lenders triangulate it from direct comparables instead, and in practice that means small multi-res in Hamilton is still trading closer to 5 to 7 percent than the sub-5 percent institutional GTA number. Combine that with resale prices that have softened noticeably over the past year while inventory has actually tightened, and you get a market where a patient buyer can still find a legal duplex or triplex that cash flows on day one, not on a five-year appreciation story.

Halton is a different animal - Oakville, Milton, and Burlington are overwhelmingly single-family stock, so the multiplex play isn't as available. The lever most of my Halton clients use instead is the legal secondary suite: a basement apartment or garden suite added to an existing single-family purchase. It doesn't turn the property into a full multi-res investment, but it can shave hundreds of dollars a month off carrying costs, and Ontario's zoning changes over the past few years have made it considerably easier to legalize.

Niagara: Where the Numbers Still Pencil for Cash Flow

Niagara is where I'm seeing the cleanest cash-flow math in the region right now. A duplex that runs $900,000 or more in Hamilton can often be found for meaningfully less in Welland or Niagara Falls, without a proportional drop in achievable rent. Investors targeting small multiplexes there are generally underwriting to 5 to 7 percent cap rates, with typical monthly cash flow landing around $1,600 on a duplex, $2,400 on a triplex, and $3,200 on a fourplex once financing and expenses are accounted for. St. Catharines and Thorold add another layer of demand - Brock University keeps a steady base of student renters that supports occupancy even when the broader rental market softens.

The Rent Side of the Equation

None of this works if rent assumptions are fantasy. CMHC's outlook for 2026 has Ontario's rental market broadly balanced, with vacancy running 3 to 5 percent province-wide and rent growth slowing as landlords compete harder to fill units. Toronto's vacancy rate hit 3.0 percent this year, the highest since before the pandemic, and rent growth there has cooled from the 9-plus percent spikes of a few years ago to the low single digits - some unit types are actually seeing turnover rents come down as landlords offer incentives to get vacancies filled. Colliers' commentary on the multifamily sector flags the same thing pressuring institutional underwriting. The takeaway for anyone running numbers on a purchase: use this year's achievable rent, not 2021's, and build in a realistic vacancy allowance rather than assuming full occupancy from day one.

Running the Math Before You Buy

The formula itself is simple - cap rate equals net operating income divided by price - but the inputs are where deals get made or lost. On the financing side, expect to put down 25 to 35 percent on income property with a debt service coverage ratio north of 1.25, which means the property's income has to comfortably cover its own debt payments, not just come close. A 50 basis point difference in the cap rate you're underwriting to can move a property's implied value by several percent, so it's worth pulling two or three recent comparable sales in the specific pocket you're targeting - Stoney Creek is not east Hamilton, and Welland is not Niagara-on-the-Lake - before you anchor on a number.

My Take

The opportunity right now isn't in chasing the lowest cap rate, it's in the gap between what institutional GTA product is priced at and what small multi-res in Hamilton, Halton, and Niagara is actually trading for on the ground. That gap exists because financing has been flat for six months and most buyers are still waiting for a rate signal that isn't the thing that's actually going to move these markets. Softening resale prices combined with tightening inventory in Hamilton, legal secondary suites in Halton, and genuinely strong cash-flow math in Niagara are, together, a more interesting setup than anything happening in the downtown Toronto core right now.

If you're weighing an investment purchase anywhere from Niagara through Hamilton, Halton, the GTA, or Toronto itself, I'm happy to run the actual numbers against what's trading in your target area. Reach out and we'll go through it together.
