Even if you're a great printer, I doubt you'll make much money, if anything at all. The greatest printers in the world still struggle to survive and even then, they have to adjust to market demands in some capacity (offer film/print scanning services, teaching photography workshops, etc.) and do not strictly do printing and film developing in the darkroom. I hope Bob Carnie will chime into this thread at some point with his experiences in Toronto and his knowledge of the printing industry.
