She should cancel all that before she left.
Her health card is still VALID. She must have renewed her driver's licence more than once and she must have LIED on the renew form to put down an address in the Province that she didn't really reside.
What is the address for her bank account? Is it the same address as shown on her driver's licence?
My wife had advised her client to cancel their health card, driver's licence, bank accounts (with some exceptions)There are certain ways to handle assets and property left in Canada. Her clients will stay in a hotel/motel whenever they returned to Canada and kept all hotal receipts. Some may have to file NR4 tax returns every year because of their rental property.
The consultation is about an hour but will save a lot of hazzle.
