Ontario Place – Ontario Place is a huge amusement park right at the foot of the city. You'll find the IMAX theater, an amphitheater, lots of places to eat, and then there's mini-golf and peddle boat rentals (peddle boats are included with the Play All Day Pass), the Thrill Zone with its interactive games, as well as some more unique experiences:
The Water Park alone has a ton of choices: Rush River, a huge waterslide 873 feet long, The Pink Pipeline shoots you on two-man tubes along twists and through dark tunnels, the Hydrofuge is like the world's longest slip-n-slide, dunking you into a six foot pool.
