My dear friend C reports that if you are lucky enough to reside in Montreal, you can get a grant for writing a short film (not a feature) from SODEC (la Société de Développement des Entreprises Culturelles), even if you have no feature credits. (I always mispell it "SODEQ," but apparently the Q is understood.)
You can also wangle some dollarettes out of the Conseil des Arts et Lettres du Quebec, but only for "an artsy, 'auteur,' cultural project. Not something commercial... God forbid." She adds: "Of course, only a small percentage of the $ goes to English-language projects but at least they give you feedback and it puts your name on the map with them so maybe they'll take you more seriously the next time around."
