An only slightly modified version of the CBC's Newsworld channel was on DirecTV for years. Eventually the US distributors (NBCU) sold the slot to the world's greatest snake oil salesman for his "world is coming to an end" channel.
There also was a channel called Trio, also distributed by NBCU, which the original format was to show Canadian dramas, including Black Harbour and North of 60, not seen in the USA. They changed the format to an "arts" channel, and that failed and the slot become Slueth.
