Five Factors for determining if a Housing Market is in a Bubble

Toronto needs a stable real estate market, not a red-hot housing bubble. Rapidly rising prices make home-ownership increasingly unaffordable, encourage speculation, inflate household debt, and price younger generations out of the market. When bubbles burst, homeowners can lose equity, buyers disappear, and the construction industry suffers. A stable market with gradual, sustainable price growth benefits buyers, sellers, homeowners, and the broader economy.

Housing should be treated as a long-term investment and a basic necessity, not a speculative get-rich-quick scheme.

Five important factors can help determine whether a real estate market is experiencing a speculative bubble. Each factor is rated from 1 to 10, where 1 means little evidence of a bubble and 10 means extreme bubble conditions. The ratings assess underlying vulnerabilities, not necessarily whether prices are currently rising. A market can remain overvalued even while prices are falling.

1. Housing Affordability

Toronto rates 9 out of 10.

Why? Home prices remain far beyond what many ordinary households can comfortably afford relative to their incomes.

2. Price Growth vs. Fundamentals

Toronto rates 7 out of 10.

Why? Years of price appreciation outpaced economic fundamentals, although recent declines have reduced some overvaluation.

3. Speculative Investment

Toronto rates 7 out of 10.

Why? Investor-driven condo construction and expectations of resale profits contributed to distortions, especially in small apartments.

4. Household Debt and Mortgage Risk

Toronto rates 8 out of 10.

Why? Large mortgages, refinancing pressures and rising arrears leave some homeowners financially vulnerable.

5. Market Demand and Supply Imbalance

Toronto rates 4 out of 10.

Why? Sales are weak and inventory is relatively plentiful. Current conditions show little evidence of a renewed buying frenzy.

Toronto's Overall Real Estate Bubble =

35 out of 50

Measured Inversely, that gives Toronto a score of 30 out of 100. A Failing Grade.

This indicates Toronto has high underlying vulnerability.

Toronto is no longer experiencing the same speculative frenzy seen during its earlier housing boom. GTA benchmark prices fell 4.3% year-over-year in October 2026, while sales fell 7.9%.

However, serious vulnerabilities remain. The Bank of Canada has documented speculative condo investment, while CMHC reports rising mortgage stress and persistent affordability problems.

 

Therefore... Toronto's housing bubble is currently deflating, but that doesn't mean the market is fundamentally healthy. It is still getting a Failing Grade. The greatest danger is that inflated valuations, high debt and weak affordability could continue to destabilize the market for years.

 

Next...

 

Let's compare Toronto to a city that has a very stable housing market.

 

Winnipeg, which rates as a 14 out of 50, or 72 out of 100 if Measured Inversely. A passing grade.

1. Housing Affordability is 3 out of 10.

• RBC estimates ownership costs at 32.6% of median household income. Affordability has weakened slightly but remains relatively manageable.

2. Price Growth vs. Fundamentals is 3 out of 10.

• Regional detached prices rose 3% annually in October, suggesting moderate growth rather than runaway appreciation.

3. Speculative Investment is 2 out of 10.

• Less apparent evidence of speculative excess than Toronto's investor-heavy condo market. This is a provisional assessment.

4. Household Debt and Mortgage Risk is 3 out of 10.

• CMHC anticipates comparatively limited increases in mortgage arrears, although borrowers still face financial pressures.

5. Market Demand and Supply Imbalance is 3 out of 10.

• Inventory rose 13% annually, while sales stayed close to their five-year average, suggesting improving balance.

 

That makes Winnipeg one of the more affordable cities to live in.
