The Big Breakfast was a Canadian morning news and entertainment program, that aired on the A-Channel stations and CKX from 1997 to 2005. It has no relation to the UK show of the same name.
On December 1, 2004, CHUM Limited officially took over ownership of the A-Channel system, and the stations were re-launched as Citytv on August 2, 2005. The Big Breakfast was also relaunched as Breakfast Television, the name Citytv uses for its similar morning shows, on the same day the stations were rebranded. The A-Channel brand was subsequently transferred to CHUM's former NewNet stations, whose own morning programs were retitled A-Channel Morning.
