Well you're right about that except that they 6 years to sue in BC, so there's a couple of years left. A moot point assuming she won't have an estate of any worth left.
If they find out which bank and branch she gets her money deposited into, they could try to attach (seize it), but that would only occur after a judgment had been defaulted on, they would only get away with it once, and could be returned once the source of the deposits were established. They have 2 more years to file a suit, but anyone who was going to sue would likely have done so long ago, though I've seen exceptions in the case of purchased debts.
If the creditor knows about her situation, they will be unlikely to pursue the matter for long.
