A Category B service (formerly Category 2 prior to September 1, 2011) is a Canadian specialty television channel which, as defined by the Canadian Radio-television and Telecommunications Commission, may be carried, optionally, by all digital cable television and direct broadcast satellite providers.
Unlike Category A services, Category B services are not protected as to format. They are licensed to broadcast within defined formats which are not provided by or overly close to an existing protected channel, but their formats are not protected themselves and need not protect other Category B services. Also unlike Category A services, a Category B service does not have guaranteed cable carriage rights, but must directly negotiate carriage with cable distributors. Category B services encompass both pay television and specialty channels.
In December 2012, the CRTC exempted from formal licensing services with less than 200,000 subscribers that would otherwise meet the definition of a Category B service, and services which air 90% of their programming in a language other than English, French, or languages of aboriginal peoples in Canada.
