Depending on your situation, I suggest your first approach to finding a rental apartment or home would be to visit a website called Kijiji. This site is currently the best source for rental units in Waterloo Region. The next best option is to drive around and find the area you want to live in. A lot of landlords first start their tenant search with a sign in the window. I do have access to rentals on the real estate board (most of which are of a higher end of rental units and houses).
