I have to differ with another poster - i would NEVEr drive a car with non-functional power steering...
anyway, the power steering pump is not hard to change yourself. If you can change the belt you probably have the ability to change the pump too.
You could take a chance on a pick-a-part junkyard if they have those in your area (although maybe it is not the season to be wrenching outside up there in the great white north).
A new one from napaonline lists for $209 (this price assumes $100 core. Last time i checked the canadian dollar/american ditto exhange rate was very close to 1:1).
