Which street should we take a stroll down to get to the lake from the Thompson Hotel?

So I'm at the Thompson Hotel and plan on visiting the Ripley's Aquarium today if a route neat there is better. I was looking at Google Maps and I noticed the lake is nearby. There are many streets to walk down south but which street is not blocked off to pedestrians and actually leads near the lake with an interesting place to hangout or a good view to walk around in.
