The company also distributes a limited number of American network affiliates from markets such as Boston, Rochester, Buffalo, Detroit, Minneapolis, Spokane and Seattle. Some Canadian cable companies use Shaw for these services where cost or technical issues prevent the use of a closer non-Shaw signal, even when the station is from a different time zone. (However, use of the Shaw feeds is not "required" for these services; cable companies are free to use any signal provider whose distribution is technically feasible.)
