In 1959, the present south grandstand was constructed with a seating capacity of approximately 15,000. New washroom and concession facilites and new Tiger-Cat headquarteers were also added in time for the Royal Visit on July 2, 1959.
On December 9, 1970, the Parks Board voted to rename the former Civic Stadium as Ivor Wynne Stadium to honour Ivor Wynne for his contributions to the Parks Board, Mc Master University, and the local and national sports scenes. Renovations took place the following year and included the addition of the north stands and the first Astro Turf playing surface in Canada. The installation of the turf was made possible by the fundraising of the Hamilton Junior Chamber of Commerce.
In 1986, a new press box was installed, as well as accessible seating and ticket booths. The site was officially named again on February 9, 1988. Ivor Wynne Stadium will be the site of the 1996 Grey Cup.
