In still other cases, a politician may run in a district other than the one they live in for personal reasons — such as having an established power base in that area from a prior political office, or simply not wanting to get drawn into a nomination contest with an existing incumbent. For instance, Jack Layton represented the electoral district of Toronto—Danforth for the entirety of his term as a member of the House of Commons, even though his personal residence was in the nearby district of Trinity—Spadina. Trinity—Spadina was concurrently represented by Layton's wife, Olivia Chow, and both districts corresponded to the areas that Chow and Layton had previously represented on Toronto City Council.
