McGill with bad ALevels grade

What would my chances be to enter macgill’s faculty of agriculture and environment AND major in ecological agriculture with my ALVELS result of BCC ? When requirements are BBB.
I have ton of extracurricular and I heard McGill doesn’t really care for it and look solely into academics? I’m not sure how competitive is my program but do you think I might make the cut?

McGill admits strictly by grades and for Americans SAT/ACT score. I am not familiar with A Levels but if they are below the minimum chances are slim to nonexistent.
