First of all, are you from Sask? U of S will only accept so many people from other provinces.
Pharmacy experience does help. This doesn't necessarily mean work experience, so if you already have a job or feel like you don't have enough time for a job, then try to do something like a job shadow. Contact a few pharmacies around town, asking if they'd be willing to take you on for a few shifts.
Does U of S require an interview? I can't remember. If so, I'd imagine it would be pretty important. Typically when a school requires an interview, they invite all people they consider potentially excellent students and use the interview as the final filter.
The personal profile is likely also highly considered, especially if an interview is not required. If you want someone to check it over, send it my way.
