Amphora is still a widespread OTC in Canada - I smoke brown (original blend) on occasion. The pouches don't denote who the importer is, but I suspect either the Scandinavian Tobacco Group Canada (responsible for most Canadian OTC's, including Capt. black and Sail) or Imperial Tobacco...although those are just guesses.
Perhaps if you shoot them a letter, they can direct you to a vendor? Worth a shot at least...
The pertainent info provided is as follows:
