## Inventory Growth Outpaces New Supply

Active listings in Halton Hills stood at 312 units on October 10, 2026, up from 260 units recorded on September 28, 2026. This increase reflects a growing pool of available properties within the city's residential market segment during this period. The rise in active inventory provides more options for prospective buyers seeking homes in the area.

New listings fell by 18.88 percent year-over-year to 159 units as of October 10, 2026. This decline contrasts with the growth in active listings, highlighting a potential slowdown in fresh supply entering the market. The divergence between these two metrics suggests that existing inventory is accumulating faster than new properties are being introduced. Sources:

Watch: Sustained drop in new listings below 100 units monthly. Confidence: low. Sources:
