Editing Simultaneous substitution (section)

===Network schedules===
Since private Canadian broadcast networks such as [[CTV Television Network|CTV]], [[Global Television Network|Global]], [[CTV 2]], and [[Citytv]] often rely heavily on American programs, their programming schedules are often effectively dictated by the schedules of corresponding United States network broadcasters.<ref>{{cite book |title=Canadian Television Today|author=B.

Many American networks telecast their most popular programming during [[prime time]], meaning that in order to maximize simsubbing opportunities, Canadian private broadcasters are often unable or unwilling to broadcast their own original programming during these hours. As a result, [[Canadian content]] programming is commonly scheduled as a secondary concern, to fill holes where an American program cannot be placed for substitution. This issue has also extended beyond scripted entertainment programming – all three major networks in Canada have faced criticism for at least one incident in which the network seemingly deemed a live Canadian news or cultural awards program to be less important than simsubbing an American [[reality television]] series:
* In 2006, [[CBC Television]] received criticism after it announced plans to bump its primary network newscast, [[The National (TV program)|''The National'']], to a later time slot one night a week to broadcast the short-lived singing competition series ''[[The One: Making a Music Star]]''.<ref>[https://www.cbc.ca/news/entertainment/nash-slams-cbc-while-accepting-award-1.612538 Nash slams CBC while accepting award], CBC.ca, June 23, 2006</ref>
* In 2007, CTV was forced to back down on a plan to [[broadcast delay|tape-delay]] the [[Juno Awards of 2007|2007 Juno Awards]] to maintain its simsubbing rights to an episode of ''[[The Amazing Race]]''.<ref name="Junos"/>

Since 2008, CTVglobemedia (now [[Bell Media]]) has held both the exclusive rights to the [[Canadian Football League]] and the rights to Sunday afternoon and playoff games of the American National Football League, broadcasting most NFL games on CTV, while relegating CFL games (including the Grey Cup) to cable channel [[The Sports Network|TSN]], making CFL games unavailable on broadcast television for the first time in Canadian history. The move was in part due to the desire to gain simsubbing rights over the NFL broadcasts, something that was not necessary for CFL games because, as of 2015, those games are only available on cable television in the United States.
