Canadian broadcast laws FTL.
According to Wikipedia:
Due to a CRTC technicality, cable and satellite companies in Canada are only permitted to carry the over-the-air Atlanta station, and therefore most now carry WPCH ("Peachtree TV") instead of the nationwide TBS channel that American viewers receive.[1] This dated back to prior to the change, when TBS programming was offered to Canadian viewers through WTBS, not the national cable channel. Many cable companies were apparently unaware of the changeover until after it occurred.[2] As a result, should Canadian cable companies wish to air "cable" TBS, it will be several months before the necessary approvals are received. It is also available in the Philippines and the United Kingdom on their various cable providers.
