Barrhaven's Greenbank road: Phase 1 is only 15% of the job

The correction first

On August 5 I wrote that phase one of the Greenbank Road realignment runs "from Chapman Mills to Cambrian" and includes a new bridge over the Jock River. That is wrong on both counts. I pulled it from a councillor's summary of the Transportation Master Plan and did not check it against the city's own project documents. I have now, so here is the corrected version of the Barrhaven post, because Greenbank is the road most Barrhaven buyers will actually feel.

What the city's documents say

The city's June 2025 project FAQ puts Phase 1 "from Riverboat Heights to Cambrian Road." The Jock River bridge is not in it. The same FAQ says Phase 2 includes the new bridge and "will proceed as soon as funding becomes available."

The FAQ also gives two numbers. The whole project is about $380 million. Phase 1 is expected to cost about $58 million.

58 / 380 = 0.1526, so Phase 1 is 15.3 per cent of the project. The other $322 million (380 minus 58) is tied to funding the city says it still has to secure. The road that Half Moon Bay commuters want is the finished one, from Chapman Mills down to Barnsdale Road with a river crossing in the middle. What has been funded and started is the southern slice.

Construction was slated to start in spring 2026. A local Barrhaven outlet reports that Phase 1 is under way, with lane reductions, staging and signed detours along Greenbank, and the city says local access is maintained for cars, pedestrians and cyclists throughout. I could not find a completion date in anything I read, so I am not going to give you one.

What Phase 1 actually builds

The city's March 2025 presentation describes Phase 1 as two lanes in each direction with a vegetated median that is interim. The median is where the bus rapid transit lanes eventually go. So the first phase is a four lane road, not the four lane road with buses running down the middle that the renderings show.

January 2026 coverage of the construction announcement described what Half Moon Bay residents live with now: a trip of about twenty minutes to get out of the neighbourhood, because there is no interchange there. The city's own phasing puts the river bridge in Phase 2, so I would not expect Phase 1 by itself to fix that trip.

I want to be direct about the difference between the two things I have now written. In August I told you Greenbank was funded and building. The accurate version is that a piece of Greenbank is funded and building, about 15 cents of every dollar, and the piece that would change the commute is not.

How I would price a Barrhaven house against this

Three rules.

First, a listing that leans on the new Greenbank corridor is describing a road that does not exist yet in the form the brochure shows. Pay for what is built, and treat the bridge and the median buses as an upside you do not owe the seller a dollar for.

Second, if the house is near the Phase 1 stretch, ask about construction before you write the offer. The city says access is maintained, and a lane reduction still changes what your driveway looks like for a couple of years. That is a fair reason to negotiate, and a fair reason to be patient as a seller.

Third, keep the segment in view. The August OREB release has the Ottawa townhouse benchmark at $547,300, down 4.0 per cent from a year ago, while single family is up 2.2 per cent. Townhouse months of inventory moved from 3.0 to 4.1 in one month, which I covered in the inventory jump post. Barrhaven is townhouse heavy. OREB does not publish a Barrhaven only benchmark that I could find, so I am not going to invent one. What I can say is that a road project with an unfunded second phase is not the thing that will rescue a townhouse price in a segment that is running four per cent negative.

Where this leaves the earlier reasoning

The conclusion of the August post survives. The train is not coming soon, and you should not pay a premium for it. What changes is the road. In August I treated Greenbank as the reliable piece of the Barrhaven story. It is reliable at about 15 per cent, and the rest is a funding request. The next thing that scores this is the city's next capital budget. If Phase 2 shows up funded there, my 15 per cent gets revised up, and I will say so here.

If you are buying or selling near Greenbank, browse what is listed in Barrhaven and then call me before you decide what the road is worth to you. I sell houses. I am not a traffic engineer or a city planner, so check the project page on ottawa.ca for the current construction notices, and I will check the listing side.
