We were there on Sunday. We parked in a parking lot up the street, forget the name, but if you come over the bridge going towards Toronto, just after the bridge, turn right, the road takes a curve left and on the left is a parking lot.
We saw all the usual ones plus WWScoter, 2 Surf Scoters, Ruddy Duck etc etc etc. As you come onto the edge of the canal, keep an eye out in the first tree on the left, think it was a Hawthorne, my husband found a mocker in there. Did not see the Peregrines, but were at Lasalle earlier and think we saw an eagle sitting waaaaaaaaaay out on the ice.
Good birding
