I guess there's really three main options.
1) Cut expenses to the bone and try and put out that hair-fire. Sell anything of value (even her home if she owns) to settle the debt. Perhaps nudge her toward Dave Ramsey?
2) Calling all financial institutions and trying to renegotiate rates, or consolidating debts into a single large debt with a lower interest rate.
3) Declaring bankruptcy. What's bankruptcy law like in Canada, and would it affect her employment?
Just wondering, is she in control of any money as part of her job (authorising payments, processing payroll/accounts, etc?)? If someone's in control of money at work and is in significant personal financial stress, there's a higher risk of employee fraud.
