Canada Maple Leaf Card Mexico Cruise Require A Visa Is There A Way To Apply For A Study Visa To Canada Fast?

Is there a way to apply for a study visa to Canada fast? - canada maple leaf card mexico cruise require a visa

I am going to study in September in Canada and received the acceptance letter, the problem is that it takes at least 4 weeks in order to apply for a student visa, and sometimes 16 weeks!
I used to live in Canada as permanent residents, but I am not a citizen, I am not yet 18 years old and my parents never lived long enough to obtain citizenship. Is there a way for me back to Canada when we were there for 4 years and havent got the Maple Leaf card? I do not want to apply for a student visa if there are other possibilities. thank you guys
