The current Town Hall was restored in 1985 to accommodate staff serving a population of 32,000 in Milton. With a rapidly growing community, an approved Town Hall Expansion plan (formerly Civic Facilities Feasibility Study) is now being put into action. The Ventin Group will design the expansion and renovations for Town Hall Victoria Park. Starting in 2006, the first phase of expansion will take place, with the second phase of construction scheduled for 2013. The facilities adjacent to the existing Town Hall, including 155 King Street, 48 Hugh Street and facilities on Mary Street adjacent to Victoria Park Square, are being reviewed as the design is being finalized.

To maintain Milton Council's goal of uninterrupted customer service delivery during the construction of Phase I, transitional arrangements for staff are now underway. On June 3, 2005 the Town took possession of 555 Industrial Drive, located west of Bronte St. and north of Steeles Avenue to implement transitional staffing arrangements for some Town staff during the expansion construction. The Staff Transitional Plan included the relocation of staff from Engineering Services, Planning & Development and Community Services to the first floor at 555 Industrial Drive, occupying up to 24,000 square feet. These departments relocated to 555 Industrial Drive, now known as Town Hall Annex 555, at the end of August 2005.
