Regarding pre-pharm, I agree that you should do it anywhere BUT U of T - your marks will be at least 10% better at any other university, I guarantee you. Also I disagree that U of T rarely accepts orgo from other schools; plenty of people in my class took it elsewhere and got exemptions. What's important is that you take a full year of orgo (i.e. 2 semesters) with a lab. The people who didn't get exemptions for orgo from other schools had either not taken a lab component or only had one semester.
In terms of EC's, I totally disagree with the first 2 posters. Maybe they're changing the application process for the PharmD but when I applied two years ago, U of T looked at two things and two things only - your marks and your UTPAT score. They don't give a crap about your EC's, or if you've had pharmacy experience. If you like to do ECs and spending time on them doesn't lower your GPA, then do them - but don't do it just for your application... unless you're also applying somewhere that looks at them.
