Why Square One Condo Prices Fell While Sellers Pulled Back

Why Square One Condo Prices Fell While Sellers Pulled Back

In the second quarter of 2026, Mississauga City Centre had about 30% fewer new condo listings than a year earlier. Buyers closed slightly more sales. The average price still fell by roughly a tenth. That combination is backwards from what basic supply and demand predicts, and the cause matters to anyone weighing a condo near Square One. Prices along this stretch of Hurontario Street are being set by what the units rent for. They are not being set by the light rail line under construction outside the lobby doors.

So a condo bought here today is priced on a rental market that is still softening, and the line is effectively thrown in at no added cost. Whether the line matters to you depends on how long you plan to hold.

The supply side tightened and prices fell anyway

TRREB's quarterly community report breaks Mississauga into neighborhoods, and City Centre is almost entirely condo apartments. Here is the same quarter compared year over year.

City Centre condo apartments Q2 2025 Q2 2026
Sales 138 145
New listings 695 485
Average price $552,000 $497,000
Median price $534,000 $485,000
Average days on market 34 35

In Q2 2026, the sales-to-new-listings ratio for City Centre condo apartments was 30%. Using the Q2 2025 figures in the table, the same ratio a year earlier works out to about 20%. By that measure, the market moved meaningfully toward sellers. Sellers still accepted lower prices, and the average sale in Q2 2026 closed at 97% of asking.

The city-wide monthly figures have kept moving the same way since then. In August 2026, Mississauga condo apartments averaged $495,052, down from $549,936 in August 2025. That is a 10.0% drop. Over the same month, the average GTA condo apartment fell 3.6% to $617,593, according to TRREB's August Market Watch. Mississauga condo prices fell nearly three times as fast as the regional average.

A drop that steep alongside a thinner supply of listings points to buyers who are pricing these units against something specific. For most condos near Square One, that something is the rent.

Rent is the number the buyer is solving for

A large share of condo demand in a district like City Centre comes from investors. Investors set their bids from the rent a unit can earn. When rents slip, the price an investor can justify slips with them, and owner-occupiers end up bidding against that lower ceiling.

Mississauga rents are slipping faster than in the cities around it. The Rentals.ca and Urbanation report on August 2026 asking rents puts the average Mississauga one-bedroom at $2,059, down 4.3% from a year earlier. Two-bedrooms averaged $2,461, down 4.9%. The same table shows Toronto's two-bedroom asking rent up 0.3% and Oakville's up 0.4%. Mississauga is the outlier on its own side of the regional market.

The two figures do not move in lockstep. City-wide condo prices fell about 10% year over year in August, while asking rents fell roughly 4% to 5%. Prices dropping faster than rents means buyers now want more rent for each dollar they pay than they did a year ago. The Mississauga discount comes partly from weaker rents and partly from buyers demanding a bigger cushion before they commit.

Where the extra rental competition comes from

The softness in rents has a source. Urbanation reported in July 2026 that record condo completions over the previous two years had pushed a record volume of investor-owned units into the Greater Toronto and Hamilton Area (GTHA) rental pool. In June 2026, Canada Mortgage and Housing Corporation (CMHC) described competition from investor-owned rental condos as higher than usual and said it was slowing absorption in larger markets.

The regional rental picture has started to stabilize. Urbanation counted a record 18,923 GTHA condo lease transactions in Q2 2026, up 5% year over year. Active rental listings fell 13%, and the average GTHA condo rent of $2,545 was down 1.3% from a year earlier but up 2.5% from the previous quarter. Mississauga's August asking-rent figures do not yet show that recovery.

New supply near Square One also keeps arriving on a set schedule. As of October 2025, RENX reported that M City's roughly 900-unit M3 tower was scheduled to begin occupancy in Q1 2026. M4, with 954 units, was scheduled for Q1 2028 occupancy, and M5, with 430 units, was scheduled for completion in 2028. Each of those occupancies adds investor units that compete for the same tenants.

The LRT has no date that buyers can price

This is where the transit line comes in. A rail line raises nearby values when buyers can count on it. The Hazel McCallion Line has not yet given them a date to count on.

The line runs 18 kilometres with 19 stops along Hurontario Street, from Port Credit GO to the Brampton Gateway Terminal at Steeles Avenue. Its timeline has moved several times:

  • 2024: the contractual completion date, which was missed.
  • November 2025: Mayor Carolyn Parrish told INsauga she did not expect riders before 2029.
  • April 2026: Global News reported that Metrolinx was privately targeting spring 2028 to finish construction.
  • May 2026: the mayor said 2028 was starting to look like a realistic completion date.
  • August 11 to 18, 2026: Metrolinx ran slow-speed tests at 10 km/h on Edwards Boulevard and Topflight Drive. Reporting at the time noted that more extensive systems testing and a revenue-service demonstration were still required.
  • August 11, 2026: Metrolinx CEO Michael Lindsay said 75% of the track work was done, 8 of 14 traction power substations were energized, and civil infrastructure should be finished "by roughly this time next year."

After the civil work comes testing and commissioning. CityNews noted that, judging by the Eglinton and Finch West lines, testing could push the opening to the end of 2027 or into 2028. Metrolinx has said it will give a tentative date only once systems integration is complete and the project reaches the revenue-service demonstration phase. Metrolinx has linked the delays to utility relocation, keeping traffic moving in a busy corridor, pandemic-era labour and supply problems, and coordinating major crossings. The intersection of Topflight Drive and Hurontario was dug up and rebuilt in 2025, which CityNews attributed to "track rework" and deficiencies.

An investor building a rent model cannot credit a line that has no opening year. The model has only this year's rent to work with, and this year's rent is falling. That is why the City Centre table shows fewer listings alongside lower prices. The market is pricing current income against current construction and leaving the line out of the calculation.

What this changes at the offer table

The two kinds of buyer near Square One face different math.

For an investor, the analysis is the familiar one. Mississauga asking rents fell in August 2026, and nearby towers keep adding units. The price a unit can support depends on where rents settle, and a rail line arriving years from now does nothing for this year's lease.

For someone planning to live in the unit for years, the City Centre data describes a different trade. Prices currently reflect a rental market that has softened more than Toronto's or Oakville's. The prices also reflect a corridor that is still a construction site, where Mississauga officials have said the work is hurting businesses and testing drivers' patience. If the line opens within the window currently reported, an owner who buys now will have absorbed the disruption at today's prices and will hold a property on a working rapid transit line. If it slips again, the buyer has still paid a price set by rent rather than by expectations about transit.

The negotiating conditions back this up. In August 2026, Mississauga had 849 active condo apartment listings, and condos took an average of 45 days to sell. In City Centre itself, Q2 sales closed at 97% of asking. Buyers who are not depending on a rent model can use that room in a negotiation.

Quick Answers

Is the Hazel McCallion LRT open? No. As of August 2026, the only train movements were slow-speed tests on Edwards Boulevard and Topflight Drive. Metrolinx has not announced a passenger opening date.

Does the Square One loop open with the main line? No. The downtown loop serving the City Centre area is a separate project, and as of July 2026 no construction timeline had been made public.

Why do the City Centre figures stop at June? TRREB publishes neighborhood-level data quarterly. Q2 2026 is the most recent release. The August 2026 figures are monthly and cover Mississauga as a whole.

Did Mississauga prices really stay flat in August? Not according to TRREB's tables. The average price across all property types fell from $968,250 in August 2025 to $898,510 in August 2026. Condo apartments fell 10.0%.
