American sports broadcasts are widely available in Canada, both from Canadian stations and from border blasters in the United States. In order to protect Canadian broadcasters' advertising, broadcast stations can invoke simultaneous substitution: any cable or satellite feed of an American station broadcasting the same program as a Canadian broadcast station must be blacked out and replaced by the Canadian feed. This rule is part of the reason the NFL, which is broadcast on terrestrial television in the United States but has no direct presence in Canada, is also broadcast on terrestrial TV in Canada, while the CFL no longer is (the CFL is broadcast only on cable in the United States); the simultaneous substitution benefits are not extended to cable stations. For the purposes of regional sports broadcasting, the Toronto Blue Jays and Toronto Raptors both claim all of Canada as their "territory," allowing Blue Jays and Raptors games to be broadcast nationwide.
