Toronto is the place for great scenic views.  A popular one is the CN Tower, not only is the ride up breath taking so is the view of the city (360*degrees).  Just pick a spot and enjoy the view with your own eyes or through a telescope. 

If that attraction does not captivate you then visit high rise restaurants that offer a fine dining experience and a phenominal view of Toronto, such as Toula (Westin Harbour Castle hotel), Panorama or Canoe. 

Need to see more, but in a different frame?   The Scarborough Bluffs, High Park and the Toronto Islands are just a few parks that offer serene views.
