Post Baccalaureate Diploma in Artificial Intelligence also called as PBD in AI is designed for students from non-computer background. They will start teaching C++, Computer organisation and so on from basics. So better you opt for Master in Advanced Computer Science also called as MACS.
If you are willing to get into Artificial Intelligence there are also subjects related to AI in MACS.
MACS - M.S degree you will get 30 points when applying for PR.
PBD in AI - PG.Diplomo course you will get only 15 points when applying PR.
Frankly speaking, if you join PBD in AI in STFX you will not gain enough skills to get a Job in AI after graduation for sure. It is just a course designed by STFX to lure international students who are willing to pay hefty tuition fee. MACS will cost you just 30K CAD, but PBD will cost you 40K CAD it is 10K more.
in PBD in AI you will be studying around 18 subjects out of which few are non-relevant to Machine Learning but part of computer science.
To keep it short just opt for a Masters degree and look for course with tuition fees around 30K CAD.
