Firstly you are reading''Cardiff Toronto US (south west)'' wrong! There is no Cardiff in Toronto, Toronto is not in the US and definatley not on the south west coast! and therefore leading to Cardiff (IN WALES), Toronto (IN CANADA) and a destination on the south west coast of AMERICA being the or some of the destinations. And due to it being the only Cardiff in the world that had a airline operate between Cardiff and Canada (Toronto and Vancouver), it must be our Cardiff....btw get your geography right. Wait and see nobody knows any more than anyone else.
Secondly with the Thomas Cook Map, they really need to sort that map out as many places have routes missing. My theory is that Hurgarda is meant to be Sharm and that as the Toronto one is only one way (YYZ-CWL) I assume it is the lasting legacy from last summer with them operating that route and they just haven't removed it yet.
