CBC, Coronation Street's Canadian broadcast station, in its infinite "wisdom", is messing around with its schedule starting August 31.They'll be broadcasting a 90 minute supper-hour news marathon starting at 5pm in all local time zones and Coronation Street is going to be pushed up to a 6:30pm start, instead of its current 7:00pm slot. Heads up for those of you that watch or record it. The Sunday morning omnibus is not changing as far as we know.
