About this property

Seller Retiring Live + Work opportunity featuring 13.8 acres with direct Highway 407 exposure and convenient access via Sixth Line in Milton. Strategically located on the border of Milton and Oakville, this rare parcel sits directly on the municipal border and within a rapidly developing industrial corridor - an up-and-coming employment zone with strong regional fundamentals. Ideal for owner-operators, strategic investors, and long-term landholders seeking both operational utility and future upside. The property has supported a well-established soil and aggregates operation since 1991, servicing Milton, Oakville, Burlington, and Mississauga. The use is grandfathered and legally non-conforming, making it suitable for topsoil mixing, landscaping, aggregate handling, contractor yards, and related activities. The current owner is retiring and the business is winding down; operations are minimal and the owner is now on-site only one or two days per week, with all on-site equipment and materials available for sale. Improvements include a well-maintained 1,620 sq. ft. bungalow with walkout basement, detached garage, 1,860 sq. ft. office/workshop, and 1,500 sq. ft. coverall structure. The site benefits from significant yard infrastructure including drainage culverts and a stormwater retention pond, offering functional advantages not typically found on comparable acreage. Zoned Agricultural and located within a growing regional corridor, the property is considered a strong candidate for future Urban Employment designation given surrounding road improvements, ongoing industrial development, and municipal growth patterns. With highway visibility, established infrastructure, and the ability to reside and operate on-site, this property offers a rare blend of current utility, lifestyle flexibility, and long-term strategic value within a highly desirable Milton-Oakville location.
