contact the faculty of the institution which you wish to attend, they will be able to tell you of any special requirements
you will need to apply as a non recent school leaver through UAC in august/september
they usually look at a combination of your UAI and first years converted gpa
for example, if you had a D average, that equates to a 96 UAI (i think)...and if you had a UAI of 80, this is what they do
(96+80)/2
=88
if this is above the NRSL cutoff, and there are no additional criterea, you will get into your course.
ps, minai explained this to me, so maybe if you want clarification, he would be a good place to start
