Does the proposed unit mix match Ottawa's housing needs?
As the 340 Parkdale proposal heads to the Planning and Housing Committee, one question is worth examining carefully: does this project help address the types of housing Ottawa actually needs?
What Ottawa’s own data says
The City’s 2024 Housing Needs Assessment identifies a clear pattern: family-sized units with three or more bedrooms are scarce, and this shortage disproportionately affects families with children, multigenerational households, and many newcomer households.
The HNA’s federal submission reports a three-bedroom rental vacancy rate of approximately 1.1% based on 2024 data.
More recent data from the CMHC October 2025 Rental Market Report puts the overall Ottawa rental vacancy rate at approximately 2.9%, with three-bedroom vacancy at approximately 1.7% — the lowest of any unit type.
Larger rental units are consistently the hardest to find in Ottawa.
What this proposal delivers
The proposed development includes 465 total units, of which approximately 5 are three-bedroom apartments — about 1% of the total. The remaining 99% are studios, one-bedrooms, or two-bedrooms.
The project contributes very little to the most constrained part of the rental market.
What the developer will say — and why the concern is still valid
Before raising unit mix at the Planning and Housing Committee, it’s worth understanding the developer’s counter-argument, because it’s policy-grounded and committee members will hear it.
The City’s Official Plan defines “large household dwellings” as either a three-bedroom unit or a two-bedroom unit of at least 850 square feet. By that definition, the developer claims approximately 75 units qualify — 5 three-bedrooms plus 70 oversized two-bedrooms — which works out to about 16.2% of the total unit mix. The Official Plan’s target for transit hubs is 10%, so the proposal technically exceeds it.
This is a real policy answer, and dismissing it without acknowledging it weakens the argument.
The stronger case is this: a large two-bedroom is not the same as a three-bedroom for a family with children. The Official Plan’s definition was designed to capture a range of household types, but the documented housing shortage is specifically for three-bedroom rentals — the units that allow families with two or more children to live in transit-connected neighbourhoods. Counting oversized two-bedrooms as a substitute papers over that gap without addressing it.
The question worth asking at committee is not whether the developer meets the policy definition — they may — but whether the policy definition is adequately capturing what Ottawa’s own data says families need.
What’s being built across Ottawa
CMHC data shows apartment construction is far outpacing ground-oriented housing. As of early 2026, approximately 14,214 apartment units are under construction in Ottawa compared to approximately 1,789 row and townhouse units.
CMHC research on missing middle housing in Canada notes that row housing plays an important role in family-oriented supply — and much of that supply is currently being delivered through greenfield suburban development, not in transit-connected neighbourhoods like this one.
The mismatch
Putting this together:
- Ottawa’s own data identifies a shortage of family-sized rental housing
- Three-bedroom units have the lowest vacancy rate of any rental category
- New apartment supply is heavily weighted toward smaller units
- This proposal provides almost no three-bedroom units
- The developer’s policy compliance rests on a definition that counts large two-bedrooms as family housing
Statistics Canada research on reasons for moving shows that households often relocate due to the need for larger housing — and that family-oriented housing is frequently delivered at the urban edge. When intensification near transit does not include family-sized homes, families move outward. Research on housing supply and urban expansion links this pattern to suburban sprawl.
This raises a fair question: if intensification near transit does not deliver family-sized homes, where is that need being met?
A reasonable ask
This is not an argument that every unit in a transit-oriented development should be large. Density near transit is genuinely valuable, and smaller units serve real needs.
But given the documented shortage, it is reasonable to ask:
- Why does a 465-unit project include only approximately 5 three-bedroom units?
- Does the Official Plan’s “large household” definition — which counts oversized two-bedrooms — actually capture the need the City’s own Housing Needs Assessment identifies?
- How does the City ensure families can live in transit-oriented neighbourhoods, if the projects being approved there aren’t delivering the unit types they need?
These are questions about how we plan the city — not just about this one site.
