Hi,
Speaking from experience I would say to definetely go for this program. I took co-op in my final year of h.s. and am currently employed at a Shoppers Drug Mart. Pharmacy schools DO look at experience working in a pharmacy. In Ontario, there is only one pharmacy school: The Leslie Dan School of Pharmacy at the University of Toronto. Competition is extremely high so any experience would give you more points than the next guy. Also, the profile test you must take when you apply might be easier to complete with any knowledge you have gained from your work experience.
Hope this helps and good luck with everything.
