Ottawa's Tewin suburb, a planned community in the city's Osgoode ward, could grow well beyond its original scope after developers filed a new application with the city to unlock more of the land for housing.
What's being proposed
Taggart and its partners submitted an official plan amendment application to the City of Ottawa the week before September 14, 2026, seeking to partially remove the Future Neighbourhood Overlay within Tewin. That overlay identifies areas where additional planning work has to be completed before development can proceed, so lifting it in parts of the site clears the way for building to move ahead there. The application is on file with the city as D01-01-26-0012.
At full build-out, Tewin could support up to 64,500 residents, a significant jump from the 14,000 residential units the project was initially proposed with. Developers now say the community could include more than 20,000 homes in total.
Where Tewin sits
Tewin covers an 838-hectare area in Osgoode ward, east of the Ottawa airport. Within that, the project area includes 445.35 net developable hectares, according to the city's Engage Ottawa page for the file.
Who's behind it
Tewin is being developed through a partnership between the Taggart Group of Companies and the Algonquins of Ontario, alongside Caivan Communities. Michelle Taggart, president, said the project is nearing reality. "Tewin is one step closer to becoming a reality," she said. "Each milestone brings us closer to delivering an innovative, sustainable community."
What it means for Ottawa
A community of this scale on the city's east end, near the airport, would mark one of the largest new-suburb pushes in the Ottawa area in years, adding tens of thousands of potential homes at a time when housing supply remains a pressing issue across the city. The official plan amendment now moves through the city's planning process, though no timeline for approval or construction has been announced. Residents who want more detail on the application can follow the file through the city's Engage Ottawa portal.
For now, the filing represents a procedural but important step: without the overlay removed, large parts of the Tewin lands can't move to detailed planning or building.
