All of the efforts at racetrack acquisitions and closures were designed to support a new "supertrack". In 1952, the OJC identified the new location of the racetrack at Highway 27 east of the Toronto airport and bought over . The architect chosen was Earle C. Morgan. Although Morgan had not designed a racetrack, he spent the next two years developing the design in conjunction with Arthur Froelich who had designed Hollywood Park Racetrack and Garden State Park Racetrack in the United States. The new track was designed to hold 40,000 spectators, have ample parking, three race courses and two training tracks. It had stable space for 1,000 horses and rooms for 700 employees. The grandstand, designed to get as many people as close to the finish line as possible, included several restaurants and cafeterias. Construction on the new supertrack began in 1955.
