Oakville’s first post office was built in 1835 and William Chisholm served as the first postmaster. The building originally stood on the southwest corner of Colborne (Lakeshore Road) and Navy Street. Through the efforts of William Chisholm’s great-granddaughter, Hazel Chisholm Hart Mathews, the building was moved to Lakeside Park in 1952 where it became Oakville’s first museum.
Today, the Old Post Office is open during the summer months for tours and hands-on postal-related activities including writing with a quill pen and creating wax seals.
