The Overview
Over the past two years, many buyers expected home prices in the Greater Toronto Area (GTA) to drop sharply once interest rates increased. While there has been some cooling, prices have not fallen nearly as much as many predicted and in some segments, they remain stubbornly high.
So why hasn’t the housing market corrected more aggressively even with higher borrowing costs?
The answer is not a single factor. It comes down to population growth, supply shortages, mortgage rules, and structural demand that interest rates alone cannot fully offset.
1. Interest rates slowed demand, but didn’t eliminate it
The Bank of Canada raised rates aggressively between 2022 and 2024, increasing mortgage costs significantly. Higher borrowing costs typically reduce home prices because fewer buyers can qualify.
And that did happen, sales dropped and prices softened in parts of the GTA.
However, research from the Bank of Canada shows that while higher rates reduce home prices, they also increase rental pressure and do not immediately solve underlying supply constraints in major cities like Toronto and surrounding regions .
In other words:
- Rates reduce buying power
- But they do not reduce housing demand
2. Population growth keeps demand structurally high
One of the biggest reasons GTA prices remain elevated is simple: demand is not falling.
Canada continues to have strong immigration targets, with hundreds of thousands of new residents arriving annually, many of whom settle in the Greater Toronto Area .
This creates:
- Constant demand for rentals
- Long-term demand for ownership housing
- Pressure on already limited supply
Even when interest rates rise, population-driven demand acts as a floor under prices.
3. Supply is not keeping up (especially for freehold homes)
Housing supply in the GTA has been constrained for years due to:
- Slow approvals and zoning restrictions
- High construction costs
- Delays in new developments
- A shift toward smaller condo units instead of family homes
According to Canada Mortgage and Housing Corporation (CMHC), Ontario, especially the GTA, continues to face declining housing starts and weak pre-construction activity, particularly in the condo sector .
When supply is limited:
- Even reduced demand does not cause large price drops
- Competition remains strong in desirable neighbourhoods
4. Mortgage rules limit how much prices can fall
Even when interest rates drop or stabilize, Canadian borrowers must still pass the mortgage stress test.
This means buyers are tested at higher qualifying rates than what they actually pay, reducing borrowing power.
As a result:
- Buyers are “capped” in how much they can borrow
- But sellers also resist lowering prices too far
- This creates a price floor in many segments of the market
A key outcome is that affordability doesn’t improve as quickly as rate changes suggest.
5. Sellers are not forced to sell
Another overlooked factor is that most homeowners are not distressed sellers.
Many:
- Locked in low rates before increases
- Have long amortizations
- Can hold their property instead of selling
This reduces downward pressure on prices because:
- Supply does not flood the market
- Forced selling remains relatively low
Without forced sales, large price crashes are less likely.
6. The GTA market is fragmented, not uniform
It’s also misleading to say “GTA prices are high” as one category.
The market behaves differently by segment:
- Condos: More price softness due to investor slowdown
- Freehold homes: Much more stable due to scarcity
- Luxury properties: Driven by wealth, less rate-sensitive
This fragmentation explains why overall averages do not show dramatic declines.
7. The key misunderstanding: rates don’t control prices alone
A common assumption is:
Higher interest rates = lower home prices
That is only partially true.
In reality, housing prices depend on a balance of:
- Interest rates
- Population growth
- Housing supply
- Investor demand
- Income levels
- Government policy
Interest rates influence the market, but they do not override structural shortages and long-term demand trends.
Final takeaway
GTA home prices remain high despite interest rate changes because the market is being pulled in opposite directions:
- Rates reduce affordability
- Population growth increases demand
- Supply remains limited
- Mortgage rules stabilize price floors
- Homeowners are not forced to sell
Until supply increases significantly or demand slows structurally, interest rates alone will not produce a dramatic or permanent drop in GTA home prices.
