I saw this a couple of hours ago and am thinking about it now. First, it left me wanting to visit Quebec City, especially during the winter. The city and its surrounding countryside looked beautiful. Some of the homes in the film, which after all is about architects, are stunning. But mainly it's the story about one ambitious young architect who actually says that love is not the be all and end all in life. He lives this philosophy in that he loves more than one woman at once and chooses not to be faithful.
The ending of the film was sort of odd in that it just happened, without showing how, and we the viewers have to assume what happened. In that assumption is confirmation of the film's meaning, i.e., Luc had to pursue his lust/love of the moment, though that didn't mean that he no longer "loved" the previous ones. He just couldn't stay with them for he needs the new and novel. He is described as ambitious with regard to his architecture, and I'd say he is with his loves, too, in that he seems to keep trying for someone new and more beautiful.
Though Luc is portrayed as gentle in his personality, and subtle, the truth is he's a selfish macho person who constantly plays sports - six different ones in the film - not including hunting, in which he shoots geese, and can't help but fall in love and get involved with beautiful women. And, he appears happy, despite some intimation of guilt; he gets over it pretty well. He is the true powerful, white male, enjoying the best that life has to offer.
