If it's been more than 2 years since you last made a payment on any debt aside from a student loan, crown debt or possibly a pre-2004 Highway 407 debt, they are all stats barred by now. If you moved to BC, the limitation period for debts in default before June 1, 2013 was 6 years, but if the contracts were from Ontario and defaulted on after Jan.1, 2004, the 2 year limitation period would apply. However, if you moved to BC before a debt was stats barred, the 6-old year rule could apply if the creditor decided to launch an action there since the transition rules on discovery after June 1, 2013 wouldn't apply. At the very least, you want to ensure you know the legal status of every debt before leaving the province.
Notwithstanding that, your situation illustrates a good point which I've brought up many times. It might appear counter intuitive, especially when you're down and out, but you want to ensure that your creditors always know where to reach you. Why? Because many times, they'll get a default judgment by mailing the statement of claim to your last known address. Then the judgment will be there forever accumulating post judgment interest at the credit card or loan rate until the day you die. Obviously, one single judgment could be enough to force you into bankruptcy at some point. On the other hand, like the song says, "if you have nothing, you have nothing to lose", so you can only come out ahead by letting everyone know where you are.
To check if there are any judgments or actions filed against you, contact the small claims court in the jurisdiction where you lived or initially took out the debts and see if any actions or judgments are listed under your name. That's the best and surest way. You can also call each individual creditor, or you can pull BOTH of your credit reports. But you'll need an address and it's never certain every creditor who could potentially sue you reports to the bureau.
There are 2 additional aspects about the limitation period expiry solution as opposed to bankruptcy. Morally, you will always owe the debts unless they are lawfully discharged in bankruptcy; and practical, because of there is no limitation period under the creditor's right of offset. If the latter is chosen, you would be wise to never put any money into ANY account of an institution which you owed money to, or you might find it cleared out without notice any time in the future.
If you open up a regular checking or savings account, the bank will almost certainly only do a soft inquiry, if any at all, which no one other than you can see.
