Council approved 132 homes on the AM radio-tower lands at 1303 Dundas Street West on April 20, 2026

What Council approved

On Monday, April 20, 2026, Oakville's Planning and Development Council passed By-law 2026-046, rezoning 1303 Dundas Street West for a low-rise subdivision. The property is on the north side of Dundas Street West between Pavilion Path and Lions Valley Park, in Ward 7. The applicant is Argo Lions Valley Ltd. In the same motion, Council authorized the Director of Planning and Development to grant draft approval, subject to conditions, to the plan of subdivision, a plan dated March 3, 2026. The motion carried, and the minutes list no public speakers on the item.

The Town's notice of passing, issued on April 29, 2026, says the by-law rezones most of the site from Future Development to General Urban, Natural Heritage System and Stormwater Management Facility zones under North Oakville Zoning By-law 2009-189, with site-specific rules, to allow a combination of townhouse blocks and detached lots “resulting in 132 dwellings”. It adds that some part-blocks will be combined with neighbouring subdivisions, for a total of 139.

The radio towers

This is the property that carried the towers of an AM radio transmitter site. Among the documents the applicant filed with the Town in January 2025 is a “Tower Dismantling Plan”: a November 2024 letter from a broadcast-engineering contractor, headed “CHWO / Argo Lions Valley”, describing how a multi-tower AM broadcast site is decommissioned. The towers are dropped by releasing their guy wires, the steel is scrapped, and the concrete foundations are broken out to about 0.6 metres below grade. The letter notes that AM sites also have copper ground wires buried across them, usually removed during construction excavation. The filings also include environmental site assessments and a record of site condition.

The transmitter shaped what could be built around it. Mattamy's neighbouring land at 3085 Harasym Trail carried a zoning hold that could come off only once the adjacent land stopped being used as an AM radio station, or once testing for interference was done. In September 2026 the Town gave notice that it intended to lift that hold, and on October 8, 2026 it did, by By-law 2026-130, with the radio towers gone.

How it got here

The Town's record shows the application was received on January 14, 2025. The first notice, in February 2025, described 131 homes. At the statutory public meeting on March 17, 2025, the applicant's planning consultant presented the plan, and Council asked staff to review the parking, snow storage and what could eventually be built on the blocks left for future development.

Those blocks are along Dundas Street. The applicant's July 2025 planning addendum says they are designated Dundas Urban Core, are being kept as future development blocks and will need further approvals; concept sketches showing apartment buildings there are, in its words, conceptual and subject to change. The same report says the street layout was turned to run north-south, a change from the 2008 North Oakville master plan, after the agreed limits of the Sixteen Mile Creek natural heritage system shifted. The Town's application page describes the result as townhouses and detached houses on a fine-grained street network, a stormwater pond and the retained Sixteen Mile Creek natural area.

Where it stands now

The last day to appeal the by-law to the Ontario Land Tribunal was May 19, 2026. On November 9, 2026, the Town's planning applications record listed the rezoning under “Council Approval” and the subdivision as “Draft Approved”, with a draft approval date of June 2, 2026; neither was listed as appealed. Draft approval is conditional. The plan still has to be registered before lots exist and building permits can be issued, and the Town has published no construction date.
