I believe that Canadian involvement is very important. Furthermore, I heard recently that the French government support of TV5 was less than certain. If I'm not mistaken, the Canadian and Quebec governments acted together to try to convince France to continue supporting TV5.
I always feel at home when I watch Canadian programs broadcast on TV5 when I'm abroad. Both as a Canadian viewer and as somebody who has travelled around abroad, I understand the importance of TV5 and its role as a platform for Canada and Quebec.
