It's a big park! but here's where I saw the shrike on Saturday Feb 5 at 4:00:
43.5897894, -79.516106
(open google maps and copy and paste those coordinates into the "search maps" input, you will see a green arrow on the map corresponding to those coordinates)
You can see that it was on the far west side, past the yacht club, on the point heading south into the lake.
