Replying to hills on the east

I live in toronto and i was looking for some new hills to ski at so i turned to our neighbours to the south.....I came across a bunch of half decent hills in new york and so far the biggest therefore best seems to be Whiteface....if anyone who has skied there is it actually biggest in New York? and if so is there anything else around this eastern part of Us really worth skiing?
Which place has the best park? I dunno id like to ski us this year so any advice would be greatly appreciated......THANK YOU
