What should I do if I want to go to Alberta, Canada for graduate study?

First of all, you don't have to worry too much about "immigration tendency". The term "immigration tendency" is generally used when applying for a visa. According to your description, you haven't reached that stage yet, and few applicants are rejected because they are suspected of "immigration tendency" because of their professional mismatch. Many of my friends have changed their majors, so there is no problem.

Second, how do you plan to immigrate in the future? If you are studying abroad, I assume that you are going to use CEC (Experience Immigration), or you are nominated by the province. This requires you to get a degree in Canada and find a job. So what major do you choose to study? I suggest you refer to the situation of looking for a job in the future before making a decision. Diplomas and certificates are really good graduates, and it is not difficult to find a job in AB province, but the cost is higher than that of graduate students.

Thirdly, according to your current situation, I suggest you decide which school you want to study, then which major you want to study, and then contact the department's Admissions Office to ask them if your situation (IELTS 6.5) is qualified to apply. Of course, you should ask more schools and departments before deciding what to do.

I am also a step-by-step person. You can contact me if you still want to discuss it.

Hope to adopt, thank you.
