There are summer camps at the campus of Simon Fraser University as well as up in Whistler Mountain.
They are all mainly activity-based rather than academic.
Both are very good.
I went to the web site you suggest. They only offer 4 weeks camp, my plan is to be there 28 June, start camp at 30 June and end at 4 July, only for one week is enough. We would like something like creative writing, creative thinking or nature adventure. and not far from Vancouver otr torento, any suggestion?
