Hi there: funny thing, as we are considering a move up north (though I'm not sure if I can pay off my student loans in a reasonable time if I move up to Canada... my husband's from Canada so we're seriously thinking about moving up to beautiful BC if the political climate doesn't change here (and I'm thinking it might not...)
I'm a P1 at UCSF and i'm not 100% clear on the reciprocity agreements (if any) between the States in the US and the BC Province. Pharmacy licences are issued on a state level so you should look into boards of pharmacy in states like WA & OR to get started. I'll be doing the reverse (looking into working in BC with a PharmD degree) and in CA we'll be taking the NAPLEX exam (which is national) so I'm hoping that I can take a similar exam in BC and be able to continue my career there.
www.pharmacy.state.or.us/ for Oregon board of pharmacy
www.doh.wa.gov/pharmacy/ for WA board of pharmacy
hey, it looks like there is an actual section for "Application Checklist for Canadian graduates" on the Washington forms. That's interesting.
As for specific places on where you could work, I'm sorry, I don't know... but it looks like they would recognize your degree here in the States, which is great! Most pschools on the west coast offer a 'PharmD' degree, so you might be competing with them for jobs, but honestly, it sounds like good pharmacists are in high demand, so I don't think you'll be at any disadvantage, regardless of where you apply.
good luck & keep us posted!
