Given that this might duplicate some innocent victim's SIN, I doubt very
much that this is a good idea, except perhaps in dire emergencies.  Better
to decline to give it (it's surprising how many forms get accepted and filed
even if you just quietly leave that space blank) or supply a number that
will flunk the check (if anyone ever bothers to check).
