Hi there! I believe that OGS results are provided through the school that you applied to. There may be an awards website for the school you applied to or just message the graduate studies office and they can give you more information. I know you said they aren't responding but maybe give them a call? At my school it is quite informal and they simply send you an email once they have the results! I do not know how this works for international students though.
Hope this helps!
