I believe only some provinces actually require/give out stamped results. Just apply with what you have, and you'll be OK.
I am in Ontario and we do have stamped results, but I applied without actually having mine yet. If they need them, they'll update your application status and contact you asking for whatever is missing. At that point you can call the BC CFO and inquire, but I believe I heard that in BC there are no stamped results required. Maybe I'm crazy though, but if they are, they'll arrive in the mail in 4-6 weeks or so.
You don't need to have your stamped results to apply. So just apply anyway, the sooner you apply the better.
