Toronto Barber & Beauty Supply is kitty-corner from the Canadian Tire store at Bay and Dundas. This store has been around since 1937 and started out as a business that sold the straight razor door-to-door. The retail space is a little dated, but nice people and bargains await for those who enter.
I usually stop in when I'm in town to pick up the odd bottle of shampoo, comb, or other item that catches my fancy.
