Buffie Saint-Marie Carry It On, and IMDb changes

Buffie Saint-Marie Carry It On, all the executive producers, cast and crew, are Canadians, so why does it’s IMDb webpage state that Country of Origin is USA ???????

Which by the way proves there is lots of money in Canada that could be going to producing more ‘happens in Canada’ productions. So ..... DO IT !

Another thing about IMDB, its really changed. Can’t see production, box office & company info nor add a comment nor submit suggesting changes without paying money anymore. This really really sucks.
