I looked at the list of films from Canada... I think I need to intervene here. There are SO many that are not listed here because they are not on letterboxd (most are on IMDB though..)
* La donation (Bernard Emond)
* Un été sans point ni coup sûr (Francis Leclerc)
* À tout prendre (Claude Jutra)
* Les bons débarras (Francis Mankiewicz) - Best film in the Quebec history.
*Pour la suite du monde (Pierre Perrault - and many many other in the style "Cinéma direct")
* Une histoire inventée (André Forcier)
* Un Zoo la nuit (Jean-Claude Lauzon)
* Le crime d'Ovide Plouffe (Denis Arcand)
In Quebec - the French province of Canada - who wants to become a country for over 40 years now - we have two excellent film directors who died at a young age : Jean-Claude Lauzon and Claude Jutra. Claude Jutra suicided in the mid '80. He was only 56. He had the Alzeihmer disease and couldn't bear loosing his memory, so he jumped off the bridge. Jutra filled up the Canadian cinematography with excellent films. He was known internationally. In Canada, they name the festival equivalence of the Oscar, and Cannes "The Jutra". And Lauzon died in plane crash at the age of 43 ! What a tragedy for Canadian cinema. I wish they would both be alive today to blow our minds out!
Nevertheless, we have many many more and very promising one too, starting with Xavier Dolan and Denis Villeneuve who are both internationally known for their films nomination or winning at the Oscar and Cannes.
Here is my chronological list of a few best (or really worth checking out).
I must say I had a little help from my friend Lise, especially for the English movies.
