Best Niagara Falls Campgrounds?

Hello all, I'm looking for some help/recommendations on nice campgrounds in Ontario around Niagara Falls. We're thinking of making a trip up to Niagara Falls this summer, probably about a week. We would like to stay in a nice campground with full hookups in Canada. We want to make one or two day trips to Toronto sightseeing and visiting the Hockey Hall of Fame.



We would be camping with two kids (9 & 12), but the dogs will be staying home.



Sorry, I''m sure this has been discussed before, however my forum search results were not providing much help.



Thanks!

Eric
