www.car-part.com is a nationwide database of used subaru parts. i can find a $15 axle and have it shipped to me. i don't need to wait for the local place to get one. I think i've even seen some canadian yards on there as well, not sure if there are many or just ones close to the border?
with shipping or knowing someone, you've got options.
or craigslist - or kiji or whatever that board is in canada they use - there's others place people part out subarus.
subaruoutback.com would be a good place to ask for assistance in canada as well - if someone knows someone parting a car, sources of used parts, axles, etc.
I'll check it out, thanks!
