That same year, 2009, the event was upgraded to a Grade III and two years later in 2011 to a Grade II.

The event has become the highlight of the meet and attracts fine fillies and mares from Canada and USA including dual winner of the event Informed Decision who later won the 2009 Breeders' Cup Filly & Mare Sprint, and Groupie Doll won the Breeders' Cup Filly & Mare Sprint in 2012 and 2013.
