MSNBC has a Budget Travel article about an Easter Canada tour that includes a visit to Niagara Falls:
The next morning, you’ll head south for a 90-minute bus ride along the shores of Lake Ontario to iconic Niagara Falls. Upon arrival, the group will board the Maid of the Mist for an hour-long boat ride to explore the dramatic falls from river level. For the adventure-inclined, an optional helicopter ride over the falls offers spectacular photo ops of dazzling sights that include Rainbow Bridge, the steel-arch bridge connecting Canada and the United States, as well as the 2,220-foot-wide crest of Horseshoe Falls.
