That being said, the waterfront trail is accessed from Kew Beach in the East, not Scarborough at all. In fact the waterfront trail ends and can be picked up to the east in 22 km which is quite a trek of overhauling over rough terrain with your bike to get to where it begins again. I always prefer going west for this reason only.
I've comfortably been able to ride my bike from Toronto to as far west to Bronte and beyond going west using the Waterfront trail this past summer.
The entire trail runs along Lake Ontario and covers an expanse of about 350 kilometers. On the western shores of Lake Ontario it runs from Stoney Creek to Quinte West. There are dozens of access points in Toronto and Mississauga to get onto this trail.
Now there are several movie studios that earn quite a pretty penny working out of Commissioner street. Of course one of the now most popular spots at the foot of Leslie Street is the Tommy Thompson Trail (or the Leslie Spit)
Biking has taken on a new meaning in Toronto since we hosted the Panam games in 2015. Although in the aftermath of spending over $2Billion dollars constructing venues and infrastructures such as the Union-Pearson Express rail train, we were left with the most amazing bike trail ever! It's a marked path, that runs beautiful along the harbourfront right down towards the exhibition stadium and continues right through to the west.
I might add a few more pictures here later, but for now you get the idea.
