This tour highlights the downtown core and is easily done on foot by most people. Total walking distance over the day is about 10 km (just over 6 miles).
The tour completes a circuit from Yonge Street to Queen Street to Spadina to Dundas Street and back to Yonge (see map).
Of course, the length of the tour depends on how long you spend at each point. Some tourists never make it past the morning visit to the shopping mall!
