Concrete Foundations Rise Along Don Mills for Ontario Line

Metrolinx reveals early structural progress on elevated guideways and stations, but commuters face years of lane reductions and closures.
The futuristic renderings of the Ontario Line are beginning to meet the reality of concrete and steel on Don Mills Road. As BlogTO first reported, early structural work is now visible as Metrolinx pushes forward with the elevated portions of the multi-billion-dollar transit project.
At the center of the development are the future Don Valley and Flemingdon Park stations, both of which will be situated above street level and connected by an elevated guideway. BlogTO reports that at the Flemingdon Park Station site, located at Gateway Boulevard and Don Mills Road, crews have finished constructing columns for several elevated guideway piers and have begun installing steel rebar for the concrete caps that will support the tracks. Additionally, 74 bored concrete piles have been drilled for the station building, with excavation slated for early 2027.
Further activity is concentrated around the future Don Valley Station, designed as a transit hub at Don Mills Road and Eglinton Avenue East. BlogTO notes that concrete has already been poured for structures supporting the elevated guideway, and as of Oct. 13, crews have completed 44 of the 48 planned foundation piles at the station's north headhouse.
While the long-term goal is to improve accessibility—with Flemingdon Park bringing over 9,700 people within walking distance of rapid transit and Don Valley Station expected to handle 3,600 rush-hour transfers to and from Line 5 Eglinton—the immediate reality for drivers is congestion. BlogTO reports that Metrolinx has already implemented sidewalk closures and lane reductions around Eglinton Avenue East and Don Mills Road, with traffic disruptions expected to persist into late 2026 and beyond. Furthermore, a full closure of Wynford Drive between Gervais Drive and Don Mills Road is anticipated in late 2027 to facilitate the construction of the elevated guideway.

**Opinion:** Metrolinx is selling a vision of a high-tech, seamless commute, but for those of us currently navigating the Don Mills bottleneck, these concrete piers look less like progress and more like a permanent fixture of frustration. The real test isn't whether the stations look futuristic in a rendering, but whether this elevated stretch actually solves the gridlock or simply creates a concrete canopy over a parking lot of idling cars for the next several years.
