In September 2026, the benchmark price of a Mississauga condo apartment was $488,300, down 7.62% from a year earlier. The detached benchmark fell 4.65% over the same period. You might expect the least expensive homes to hold up best, since more buyers can afford them. Mississauga's numbers show the reverse, and the reason has less to do with demand than with timing. Condo towers that sold out years ago are reaching completion together, and that same slowdown is quietly cancelling the towers that were supposed to follow them.
That distinction affects anyone comparing a condo with a house this fall. A price drop caused by too much new supply can behave very differently from one caused by people losing interest in a neighborhood.
Two Sets of September Numbers
Here is how the Toronto Regional Real Estate Board's September 2026 Market Watch, released October 6, breaks Mississauga down by property type.
| Mississauga, September 2026 | Detached | Condo apartment |
|---|---|---|
| Benchmark price | $1,245,400 | $488,300 |
| Benchmark change, year over year | -4.65% | -7.62% |
| Sales in the month | 196 | 122 |
| New listings in the month | 589 | 382 |
| Active listings at month end | 919 | 831 |
| Median sale price | $1,219,000 | $432,500 |
| Average sale-to-list ratio | 96% | 96% |
| Average days on market | 30 | 46 |
Divide the active listings by September's sales and you get about 4.7 months of detached supply, compared with about 6.8 months of condo apartment supply. That is a simple one-month calculation, not an official TRREB figure, but the gap is large enough to matter. A detached house in Mississauga sold in an average of 30 days in September. A condo apartment needed 46. Both types sold at an average of 96% of the asking price. The difference shows up mostly in how long sellers wait, and every extra week on the market makes a seller more willing to negotiate.
Townhouses sit between the two. Mississauga's townhouse benchmark fell 7.04% year over year, close to the condo decline. Prices are falling hardest at the lower end of the market, where there is the most new inventory.
The Towers Sold in 2017 Are Being Handed Over Now
Most condo apartments were sold years before anyone could move in. Buyers signed in a hot market, and developers built to those contracts. When those buildings finish, the keys are handed over on the construction schedule, whatever the market is doing that year.
In August 2026, The Globe and Mail described Mississauga City Centre as an area that had carried a volume of unsold units similar to Vaughan Metropolitan Centre and downtown Hamilton. The paper reported that Daniels still had about 60 unsold units in the area as of mid-June. Dominic Tompa, president of Daniels Realty Corp., explained the timing to the Globe:
"You had a lot of projects that were sold between 2017 and 2022 and all having come to completion in the last 24 months to 30 months. You've got a lot of product that will just take time to absorb."
M City shows how large this wave is. The development by Rogers Real Estate Development and Urban Capital includes M3, an 81-storey tower of roughly 900 units. RENX reported in October 2025 that occupancy would begin in the first quarter of 2026. By August, the Globe described M3 as nearing completion and its first two towers, M1 and M2, as fully occupied. M4 and M5 are under construction.
The 831 condo apartments on the market in September include resale units from these new buildings, competing against older stock across the city. A buyer comparing a 15-year-old unit with one that has never been lived in can make sellers of both compete for the same offer.
Why Rents Can't Absorb the Extra Units
Units that owner-occupiers don't buy usually become rentals, so the extra supply moves into the rental market. In its June 9, 2026 mid-year rental market update, Canada Mortgage and Housing Corporation said Toronto-area asking rents were declining. It also said newly completed condos that had not been absorbed by the ownership market were adding competition for tenants.
CMHC's rental market survey shows the same pressure in Mississauga's purpose-built buildings. Vacancy in the Mississauga Centre/Streetsville zone rose from 1.8% in 2023 to 4.3% in 2025. In Churchill Meadows/Erin Mills it rose from 1.7% to 3.0%. Those figures cover purpose-built rentals, not condos. Even so, they show how many more empty units a Mississauga landlord is competing against than two years ago.
Asking rents have followed. The October 2026 National Rent Report from Rentals.ca and Urbanation put Mississauga's average asking rent across all property types at $2,337 in September. One-bedroom rents were down 3.1% from a year earlier and two-bedroom rents were down 4.1%. Nationally, the same report found condo rents fell 7.8% year over year, the steepest drop of any property type.
This explains why condos fall faster than houses. Many condo buyers are investors who value a unit partly by the rent it can earn. When rents fall, the price an investor will pay falls too, so prices and rents move down together. A detached house is valued mainly by the family that will live in it, and its price is less tied to rents.
The Same Slump Is Cancelling the Next Wave
Every one of those completed towers was financed during the boom. Getting the next tower built works differently.
The Globe reported that Rogers Real Estate and Urban Capital cancelled M6, a planned 58-storey tower of nearly 900 units, because presales never reached 70%. That is the share of units a developer had to sell before it could get construction financing. "As a result, all purchase agreements have been cancelled, and all deposits have been refunded," Rogers Real Estate vice-president and treasurer John Anderton said in a statement to the paper.
M6 matches a pattern across the region. Urbanation's Q2 2026 condominium survey counted 702 new condo sales across the Greater Toronto and Hamilton Area. That was up 52% year over year, mostly from units in finished buildings and bulk investor purchases. Pre-construction sales fell 80%, to 50 units. Completed but unsold developer inventory rose 68% to 5,001 units. The pipeline of units in pre-construction or under construction fell 37% to 48,710.
Put together, the region is selling what has already been built and starting very little new. Buildings in today's sales figures come from presales made five to nine years ago. Buildings that would have reached the market around 2030 or later are being cancelled now, M6 among them.
The rental market is already showing early signs of that shift. In its Q2 2026 rental report, Urbanation found GTHA condo rents down only 1.3% year over year, while active condo rental listings fell 13%. Those are regional figures rather than Mississauga's alone. They still suggest the rental surplus started to shrink in mid-2026.
The City of Mississauga is also working on future supply. Its September 3, 2026 announcement said development-charge reductions of up to 100% helped secure up to $401.4 million for housing-enabling infrastructure. The city committed to keep those reductions in place through March 31, 2029. The release also names a planned Downtown Transit Mobility Hub, which will expand the City Centre Transit Terminal and connect it with the Hazel McCallion LRT. These incentives aim to get new towers started, and the resale glut is what has been holding those starts back.
What This Means When You Compare a Condo With a House
If you are deciding between property types in Mississauga, the September numbers point to four practical points.
- The condo discount has a known cause. Much of the price drop reflects towers sold between 2017 and 2022 all finishing in the same few years, as Daniels described to the Globe. That says more about supply timing than about City Centre's long-term appeal.
- Resale units are the better value for now. The Globe reported that pre-construction prices have come down but remain higher than prices for condos that are already built, which gives resale buyers the better deal.
- Time on market is your leverage. At an average of 46 days, a September condo apartment listing sat about two weeks longer than a detached one, so buyers had more time to compare units and negotiate.
- Detached homes are softening more slowly. Mississauga's detached benchmark is still down 4.65% year over year, with about 4.7 months of supply. That is a calmer market than the condo segment, but it is not the same market as two years ago.
Over the coming months, three numbers will show whether the surplus is shrinking. These are the months of condo apartment supply in TRREB's monthly reports, Mississauga's average condo rents, and whether M4 and M5 at M City are completed on schedule. If listings fall while rents level off, the gap between condo and house prices has probably stopped widening.
Quick Answers
Are Mississauga condo prices still falling? As of TRREB's September 2026 report, the condo apartment benchmark of $488,300 was 7.62% below its level a year earlier. October figures come out in TRREB's next monthly report.
Is the oversupply limited to City Centre? The Globe's reporting on unsold units focused on Mississauga City Centre, where M City and several Daniels projects are located. The rising purpose-built vacancy in CMHC's survey also extends to Churchill Meadows/Erin Mills, so the rental pressure reaches beyond the downtown core.
What happened to people who bought presale units at M6? According to the statement Rogers Real Estate gave The Globe and Mail, all purchase agreements were cancelled and all deposits were refunded.
