Yup, so weird. These streaming services for what they are, are still so hokey in some ways, especially with the limits they impose on Canadians who still pay the going rate but are barred from a lot of content.
yes that is a bit puzzling. in the "first run movie business" as i will call it we seem to be pretty seamlessly integrated with the USA. ie. movies turn up in theatres at the same weekend and box office figures include USA and Canadian numbers.
but i guess in the aftermarket and for TV shows there are quite different right-holders in the USA and Canada.
