Learning French for French draw, how long does it take?

Hi yall, I just got my PGWP a few months ago and so I have some time (~2.5 years) to get a year of experience (I haven’t found a job yet, this is in Ontario lol) but I am genuinely considering spending a big chunk of my time learning French to get up to NCLC level 7 in French now. How long does that usually take? From my understanding, the current policy favours being bilingual more than it favours adaptability and/or experience so it might just be better to focus on learning French. Anyways, I plan to leave my home country for good and live in Canada (ethnic/religious minority in my home country that doesn’t get treated well) forever so it might just help with the assimilation too. Does anyone here have experience doing something like that?
