Ontario?

[Zarka]

I will be in Ontario, Canada for a couple months and am wondering if there are any canyons there or groups people can direct me to?

My wife is from outside Ottawa and inlaws are still there. Have yet to find anything in that immediate area but try looking across the river in Quebec. Ontario covers a fairly large area. You didn't say what city you will be in?
