On our way home from Cananda this summer my crew and I stopped off to visit Niagra Falls on the Canadian Side. This side was exponentially more picturesque than the domestic equivalent which was composed of only a large platform over the falls.
The Canadian side of the Falls offers a long stretch walkway that follows the Falls, with natural greenery and stone features that end with the National Park gift shop and Tourism center. There is also a collection of food and shopping vendors located in this building.
A little farther into Canada there is a town with more family friendly attractions including an aquarium, bird preservation, an arcade, and a Ripley's Believe It or Not! As well as a few cafe's bistro's, and boutique clothing stores. The best part is that most places in this area accept both Canadian and US currency!
