It doesn't matter if you did 5-7 years of pharmacy or you have a doctorate of pharmacy just like me, PEBC and WES will recognize any pharmacy degree (bachelor, master or doctorate) as a professional 4-year degree as the pharmacy program is only 4 years in Canada. Professional degrees such as MD, DMD or PharmD are not considered graduate degrees in canada, only general Masters and PhDs are.
Get a WES ECA only if your professional experience doesn't require licensing such as drug representative or industrial pharmacy job (jobs with no interaction with patient).
Get a PEBC ECA only if your professional experience requires licensing such as retail or hospital pharmacist (jobs with direct interaction with patients).
You will get your application denied if you don't get the correct ECA based on your claimed professional experience.
I did both because I got both experiences.
WES was very cheap and quick to get (2 weeks), PEBC was an expensive and long process (2-3 months) and more a pain because they required proof of licensing in your country and you need to have the application notarized, which is completely silly. You may have to take the equivalency exam before they can give you the ECA. I was waived the exam because I have a US PharmD.
