Your question contains a trap, and I will try to avoid it.
There are three challenges when it comes to statistics: having available, reliable and reasonable statistics. You can send a questionnaire to everyone on the planet to find out if they saw a Canadian film last week, but I'm not sure that would be very effective.
The challenge in developing public policies is to properly assess the traffic. We know, for example, that Canadian films are available on Netflix. They will print some pages, and so on. You can watch Canadian films, but who is the audience for these films? You still can't get statistics on that.
