How long for a foreign bank check to clear?

[KikoSanchez]

Ok, since neteller is out, I have received 2 checks from a bank in Canada through my poker site. The first one was promptly taken, cashed, etc as normal. Today, the teller says since its a foreign check, they'll have to send it somewhere and it may take a few days.

My real question is: is there anywhere I can take such a check and have it cashed immediately? Such as Western Union or something similar...
