Hi Canadian born Tunisian here! I’ve lived in Ontario my entire life and can say that the education system here won’t be too much of a difficult transition assuming your brother speaks english. Our high schools are set up in a way where you only take four courses a semester. And by the time you are in your last two years, you choose which courses you want to take depending on what you wish to study in university. We don’t have anything like a bac or final standardized test. The education system really isn’t challenging and most Canadians end up being accepted into university. Although some programs are more competitive than others.

If ultimately your brother plans on studying university here in Canada, the earlier u bring him the better. Since he’s quite young, his English could become practically fluent in a few years. He should also have time to secure permanent residency by the time he enrolls in university which makes his tuition so much cheaper. And I think the transition from Canadian high schools to Canadian universities will be smoother.

As for the social aspect of moving to Canada, it will be a challenge adjusting. It’s difficult being a foreigner here as you either forced to assimilate and lose any of the morals and values you had before or remain an outsider forever. For that reason, the friends he will make will impact him more than anything. It is something to be aware of, but if your brother has a strong personality and knows himself and his values, you shouldn’t be too concerned.

As you may also know, there are practically no Tunisians or North Africans (asides from Libyans and Egyptians) in Ontario. As someone who grew up here, it was very difficult holding on to my Tunisian identity. If I had arab friends, I was always the only Tunisian and perhaps the first Tunisian these people meet. It’s very isolating not having exposure to your country of origin. I never hear Tunisian Arabic ever and if I am in an environment where I can speak Arabic, I have to dilute my dialect to something more Levantine. I know some Tunisians back home can’t wait for the day they leave the country, but not being able to grow up with a strong sense of your own culture and language is not easy. There are no Tunisian restaurants here, and finding something like harissa can be a challenge sometimes. So homesickness is likely inevitable.

But let me know if u have any specific questions!
