So this should actually just forward the mail, and not rewrite
anything...

I think you'd need the full:

rwm132@engr.usask.ca rwm132@mail.usask.ca

for this to work.. but not sure...

Well... you probably need both:

@young.usask.ca @mail.usask.ca
@engr.usask.ca @mail.usask.ca

in there... And probably have to add:
 virtual_alias_domains = young.usask.ca.engr.usask.ca
to main.cf as well. (See "Mail Forwarding Domains in here:
  http://www.postfix.org/VIRTUAL_README.html )

What's making this even uglier is that you're reciving mail with the
host part being the alias of a machine... so you probably have to
account for both the real name, and the alias, when setting this
up...

However: I think if this machine is just doing simple forwarding, you
shouldn't need the "virtual" part at all -- you should just be
setup to accept mail to @young.usask.ca or @engr.usask.ca addresses,
and then rely on the aliases.db file to do the actual forwarding...

Later...
