It's the end of an era. On October 18, Calgary and Edmonton will elect new mayors for the first time in years. Naheed Nenshi and Don Iveson are not running again, and they have a few things to say before they go. For about a decade they've had a view of the cities, the province and the country that few have. This week, they join host Kathleen Petty to discuss their legacies, the future of their cities, leadership and the state of the province.
