Hi there!
Well, no matter where do you come from, we are all IMGs (International medical graduates).
If you want to pursue a specialty here, you need to take the exams, you could take the MCCEE in your country, and once here, you need to take the MCCQE1 and MCCQE2.
It depends on every province, once here, you need to make connections. I've seen those well networked applicants get in.
Good luck with all your endeavors! 🙂
