Waterloo is a small city that has owed much to the rise of the University of Waterloo over the last half century. Uptown Waterloo is the thriving, if small, downtown area. Waterloo has 100,000 residents and the University of Waterloo has 30,000 people. It’s less than 2 km between Uptown and the main UW campus. Let’s take a walk from one to the other.
