Pharmacy tech to a pharamcist is it POSSIBLE?

Reason is this I am in my last semester of sports admin jobs in Canada are not to great for the sports admin and finding out that i need a accounting or some kind of marketing degree to actually work within these offices... I wanted to get back to what i wanted to complete which is Pharmacy however my grades were in the C+ to B- minus are....Could I go and become a pharmacy tech and decide to gradually retake my courses or apply to harm school then. Or just go and retake my high school courses and will they accept them. Or shall i retake the pre requisites from the first year University courses?
