LONDON, ONT There’s been a major windfall for residents of Middlesex County, as the sale of the historic former courthouse building in downtown London has been finalized. “By all indications Middlesex County’s going to continue to grow very rapidly in a post-pandemic world,” said county CAO Bill Rayburn of the $36-million sale to York Developments, which also includes the former health unit building next door at 50 King St. In addition, the county is set to close a $6-million sale of a piece of vacant property in the west end of Strathroy, known as the Strathmere lands. The buyer in that sale is Van Bree Enterprises. The property is slated for development.
