In Canada, a television system is a group of television stations which share common ownership, branding and programming, but which for some reason does not satisfy the criteria necessary for it to be classified as a television network under Canadian law. As the term "television system" has no legal definition, and as most audiences and broadcasters usually refer to groups of stations with common branding and programming as "networks" regardless of their structure, the distinction between the two entities is often not entirely clear; indeed, the term is rarely discussed outside the Canadian broadcasting enthusiast community. In the latter regard, however, a group of Canadian stations is currently considered a "network" if it satisfies at least one of the following requirements: it operates under a network licence (either national or, in the case of Quebec where the majority of Canada's francophones reside, provincial) issued by the Canadian Radio-television and Telecommunications Commission (CRTC). Four such networks currently operate: CBC Television, Ici Radio-Canada Télé, TVA, and the Quebec provincial network V. (The Aboriginal Peoples Television Network, APTN, was reclassified as a specialty channel by the CRTC in 2013, although it continues to operate broadcast transmitters in certain rural areas.) it has at least near-complete national over-the-air coverage (or equivalent mandatory cable carriage) in Canada's major population centres. Three additional station groups meet this criterion: CTV, the Global Television Network and Citytv. If the group of stations does not match at least one of these criteria, it would then be classified as a "system". In current practice, a television system may be either: a small group of stations with common branding, such as CTV 2 or Omni Television, or a regional group of stations within a larger network, such as CTV Atlantic, CTV Northern Ontario or CBC North, which are legally licensed as multiple stations but effectively act as a single station for programming, branding and advertising sales purposes. Systems are differentiated from networks primarily by their less extensive service area – while a network will serve most Canadian broadcast markets in some form, a system will typically serve only a few markets. As well, a system may or may not offer some classes of programming, such as a national newscast, which are typically provided by a network. Finally, with regards to "primary" systems, the amount of common programming on participating stations may be variable. While CTV Two (and previously City, the Baton
