Replying to Snowpark near London, Ontario

Hi guys!!

i'm an exchange student from Spain in London, Ontario.

I would like to go ski in some ski resort from 5th to 21st of December but is so early so maybe the snowpark will not be built.

I thought to go to whistler (but its so expensive and so far from Ontario)

or vermont... Killignton?

or mont tremblant.

Which of these resorts will have the best snowpark on early season?

Thank you!!!
