Downzoning
Understand downzoning in Canadian real estate — what it is, why it’s implemented, and its impact on property development rights.
July 27, 2025
What is Downzoning?
Downzoning is the process of changing zoning laws to reduce the allowable density, height, or land use intensity on a property or in a designated area.
Why Downzoning Matters in Real Estate
In Canadian real estate, downzoning can affect property value and development potential, often implemented to preserve neighbourhood character or protect infrastructure capacity.
Impacts of downzoning:
- Lower permitted floor area or building heights
- Restrictions on multifamily or commercial uses
- Potential decline in land value or investment feasibility
Understanding downzoning is essential for property owners and developers to assess long-term land use rights.
Example of Downzoning in Action
The city passed a bylaw downzoning the area to single-family residential to maintain its low-density character.
Key Takeaways
- Reduces permitted density or building intensity
- Often intended to protect neighbourhood character
- Can decrease redevelopment potential
- May affect property value
- Requires municipal bylaw changes

National average resale-price growth and housing-starts growth, smoothed over three months. The comparison illustrates the cycle; it does not establish how much a price change causes construction to change.
Trailing 12-month starts in centres of 50,000 or more remove the usual monthly seasonality. Ownership combines the homeowner and condominium categories; rental is shown separately.
Six-month averages of provincial starts, expressed at annual rates. The smoothing reduces the influence of individual apartment projects.
The same August benchmark compared with two different starting points. Three-month changes are not annualized.
Average sale prices show the difference in purchase costs across markets. They do not measure affordability relative to local incomes or construction costs.
Newfoundland and Labrador remains above its pre-pandemic sales pattern, but August activity was below last year. Historical lines retain their original release vintages.
Average and median describe different aspects of the same month’s transactions. Both are affected by the mix of homes sold.
Category averages compare different homes and locations; the gaps are not estimates of the cost to upgrade an otherwise identical property.
The five categories shown account for 5,000 of the board’s 5,057 sales. The remaining 57 transactions were in other housing categories.
Monthly observations are not seasonally adjusted. Active listings count properties available at month-end; they are not construction inventory.
Average and median prices share one dollar axis. These unadjusted transaction measures do not control for changes in the homes sold.
TRREB’s 416/905 categories compare the apartments sold in each area. The difference does not isolate a location premium for equivalent units.
