Where to start learning French?

International student coming in this Fall. I know living in Montreal really I should at least try to learn some French, and I'm passionate in that I want to be able to communicate in French as best I can whilst living in the city. That said, I don't really know where to start/ look for getting my French up to scratch. Are there any courses (either in or out of Concordia) that might help?

Some pointers towards some great resources/ courses would be much appreciated! Insight from bilingual folk who learnt French whilst living in Montreal would be even better!
