Hi! I saw your post about trades in Quebec and I wanted to ask you a question about it. Feel free to ignore if you want to :).
I'm looking to go to Quebec for my masters (we're from ontario) but my partner is starting to get into the trades and I was wondering what level of French is needed to start an apprenticeship?
Congrats on the masters! I'm going to assume you are going to be in Montreal, both because I think we have the highest number of universities and I'm pretty sure we have the only English ones.
If not though, heads up that working on French has just become a priority. Language politics in this province are nasty, and while you'll get some assholes in Montreal, you'll get fewer of them and people are more likely to speak English.
Okay, onto your actual question. Technically, I think the answer is none. There are two paths into trades, and neither of them technically require french. So, the first, which is probably less interesting if he wants to go straight into an apprenticeship, is trade school. There are English trade schools. Not for all of the trades, and I think many have wait lists, but they do exist. There are private and public ones.
The next option is through the labour pool (basin). To do that, your partner has to find a company willing to offer him a guarantee of 150 over a maximum of three months, and then wait for the labour pool of that specific trade to open, so he can start working for them. You can check the CCQ website for more information on Labour Pools, and to check which ones are open.
So, either way, you don't technically need french. He could go to an English school or he could find a company willing to hire an Anglo. They're rarer, but they do exist. If he already has some experience, that will probably help.
Essentially, I think it boils down to "You can work here without speaking French, technically, and also, the more french you speak, the more doors open for you". By struggling with French, he will face discrimination (I know I do, and my french is good enough that I'm going to a french trade school), and he can still make it work, just be aware of the extra suck.
Good luck with the Masters Degree and I hope to run across your partner on a worksite someday, happily doing whichever trade calls to him!
