One of the most impressive structures to me is a large pavilion, constructed with soaring roof lines and lots of wood.
In between watching planes land and take off, we marvelled at the light, and were able to get some great shots of the late afternoon sky.
If you walk further west along the path, you come to the old Ontario Place grounds, which we walked into the second time we went to the park. There are remnants of the old park in its former glory; you can see the Cinesphere and leftovers from the old water park.
Trillium park will doubtless become a sought-after place for Torontonians to park themselves and their families for annual waterfront events like the airshow.
