The new racetrack opened on June 12, 1956, built at a cost of million ($ in dollars). It was initially known as the New Woodbine Racetrack. It dropped the "New" in 1963. The old track was converted to a combined thoroughbred and standardbred track known thereafter as Old Woodbine or, for most of the rest of its history, as Greenwood Raceway (during standardbred meets) and Greenwood Race Track (during thoroughbred meets). The two thoroughbred and two standardbred meets conducted at Greenwood were transferred to the new Woodbine in 1994, which was until then exclusively devoted to thoroughbred racing. On June 30, 1959 Her Majesty Queen Elizabeth II and His Royal Highness The Duke of Edinburgh attended the 100th running of the Queen's Plate, and Queen Elizabeth II again on July 4, 2010 during part of her state visit to Canada, attended the 151st running of The Queen's Plate Stakes, as well as taking part in the presentation of trophies.
