Windsor is not directly served by Canada's major commercial networks. Any commercial stations operating in Windsor would be required to purchase program rights at Detroit market rates, which are higher than any market in Canada. Additionally, the commercial networks air a large amount of American programming, and would be forced to black most of it out in Windsor to protect the broadcast rights of the Detroit stations. The city is served only by the Canadian Broadcasting Corporation's English network and the provincially owned public broadcaster TVOntario, both of which air almost entirely Canadian-produced programming, and by the smaller CTV 2 system.
