I cycled out to the end of Leslie Street Spit this evening. It’s far. I got to the concrete pad by the lighthouse: Google Maps: Leslie St Spit: 43.61374° N, 79.34352° W.
My legs hurt. A lot. But it was pretty. I saw one of the beaver-felled trees, too.
It was about 30km, down to the spit and back up to King subway
