William T. Ruddock Trophy
The William T. Ruddock Trophy is awarded to the Ontario Hockey Federation Junior "A" branch champion. The trophy was probably first awarded in 1998 as that is the first year the Ontario Hockey Association does not list a Northern Ontario Hockey Association team competing for the Frank L. Buckland Trophy. Because of the nature of the championship and the layout of the Canadian Junior Hockey League playdowns, the Ruddock Trophy is always awarded at the Dudley Hewitt Cup, since 2003 to the winner of the Round Robin game between the OHA and NOHA champions.
