You are not paying for a transmission system in Nunavut when you're in Don Valley. What you're paying for is the maintenance and upgrade of the current transmission system.
For example, in the case of Ontario, the transmission system that you're paying for increasingly is expanding to bring in new sources of renewables as Ontario moves away from coal, for example, and brings in other renewable sources of energy. Those sources are not in the middle of the backyards of people in Toronto; they're often in more remote locations. So that's what you as a customer are paying for in your transmission charge.
