Ottawa is building fewer new homes this year, and the slowdown could have ripple effects for anyone hunting for a place to live in the capital. According to the Canada Mortgage and Housing Corporation (CMHC), housing starts in Ottawa are down 10 per cent so far in 2026 compared to the same stretch last year.
What the numbers show
A "housing start" is the point at which construction begins on a new home — the moment the foundation goes in. It's one of the clearest early signals of how much new supply is actually coming to the market. When starts fall, it means fewer condos, townhomes, and detached houses will be ready for buyers and renters down the road.
A 10 per cent drop may not sound dramatic, but in a city that has spent years grappling with tight inventory and climbing prices, every unit counts. Fewer starts today translate into fewer move-in-ready homes a year or two from now, exactly when demand is expected to keep growing.
Why it matters for Ottawa residents
For the thousands of Ottawa households watching the market — first-time buyers, growing families looking to upsize, and renters hoping to find something affordable — a pullback in construction is rarely good news. When supply lags behind demand, competition heats up and prices tend to hold firm or rise, even in a cooler market.
The slowdown also touches Ottawa's local economy. Residential construction supports a wide web of jobs, from tradespeople and crane operators to suppliers and real estate professionals. A softer building season can mean quieter job sites across neighbourhoods from Barrhaven to Orléans.
What's behind the dip
While CMHC's headline figure points to a clear decline, housing starts are shaped by a mix of factors — borrowing costs, the price of materials and labour, developer confidence, and how quickly projects move through the city's approval process. Higher financing costs in particular have made some builders cautious about breaking ground on new projects until they're confident the demand will be there.
Ottawa is not alone in this; many Canadian cities have seen construction activity ebb and flow as interest rates and economic conditions shift. But the local figure is a reminder that the capital's housing supply isn't keeping pace with the ambitious targets governments have set for new homes.
The bigger picture
Federal and provincial leaders have repeatedly called for a surge in homebuilding to ease Canada's affordability crunch, with Ottawa frequently cited as a market that needs thousands of new units. A 10 per cent decline in starts runs counter to that goal and underscores how challenging it is to turn housing targets into actual shovels in the ground.
For now, prospective buyers and renters in Ottawa may want to keep a close eye on how the rest of the building season unfolds. If starts continue to trail last year's pace, the squeeze on available homes could persist well into the future.
The figures come from CMHC, as reported by the Ottawa Business Journal (OBJ).
