I was visiting Toronto for a long weekend and staying in Liberty Village. This park was the closest to my place and made my morning run a breeze. There's a nice loop close to the water, and another that runs further along the main drive (which is also a bike path). The paths are in nice condition and all are paved. It wasn't too busy in the park during Saturday/Sunday afternoon, or on Monday morning (except the trash man was out and about).
There are some nice benches here overlooking the water, a spacious dog park (that was definitely in use), and lots of shady spots under the trees. A poutine stand was parked on the corner of Lakeshore and Strachan (although I didn't try any) if you would need a snack in the park.
Not a large space, but overall perfect for what I needed.
