Now with respect to the Punjabi brothers over at Pomer and Boccia, 4110 Steeles Avenue West in Toronto: Before you pay anything or try to make any settlements with them, it's well worth noting the following:
You live in Ontario and so I'm including links on "How to Reply to a Small Claims Court Judgment When You Are in Default" and also the "Guide to Getting Results After a Judgment." See the section on wage garnishments. Because of your student loan for (gasp!) $70K, you'll likely need to ask the Court for a hearing to modify any wage garnishments filed against you. See the "Wage Act" link for garnishment rules and appeals.
But before this, there's the matter of the default judgment itself. You obviously didn't reply within 20 days and you're right in concluding that since the defaut judgment was obtained almost exactly 2 years after your last payment, they must have filed a Statement of Claim quite a bit before that period was up. There is a 2 year limitation period but it refers to the time when the creditor knew or should have known the account had gone into default and when they file the Statement of Clain (Form 7A) in Court. Even though you're out of luck on the S.O.L. period, all is not necessarily lost.
If you could have shown the Court that you were improperly served, you could file a Motion (Forms 15A, 15B) to Set Aside the Default Judgment because you didn't learn about it until the garnishment notice arrived. However, this requires that you demonstate that none of the documents arrived at your last known address. Did the plaintiff file any returned documents or letters with the court etc?
Even if you can convince the Court that you were not at fault for not being properly served, you still have to give the judge a good reason as to what your defence would have been had you been able to respond. That's why the web guide says that you have to file a Statement of Defence (Form 9A) with the court also. Or at least give the judge a half decent outline of some reasonable defense.
What to use? Well, a lawyer will tell you that one valid defence is to claim the actual amount owing was a lot less than what was awarded in the original default judgement after prejudgment interest is factored in. The problem is that this will probably fail since the judge will likely have the copies of all the credit card statements contained in your file before him.
What to do? Well, all is still not lost. Explain your desparate situation to the judge. It's important what type of impression you create, trust me. Because the judge can do almost anything he wants, he may, at this point, set aside or greatly modify (in your favour) the garnishment that was obtained and make a separate order for payment. It's impossible to say since every case and every judge is different.
Of course, if even this fails and the judge dismisses your motion outright, you can still request a hearing (after you leave the court) at a later date on your wage garnishment to be reduced. It's impossible, as I said, to give a definite answer as to what will happen, but I can tell you, if a person presents a good image (as opposed to someone who gives the impression that he is only trying to screw the Court around), they will get terms far gentler than they would get with any collection agency. I saw one lady that owed the same credit card amount as you get off with spreading payments over 30 years with no interest! That's not bad! And that was when all the above steps had failed for her! Try getting that with those collection agencies Pomer and Boccia.
By the way, those guys at Pomer and Boccia are gross liars just like all other collectors, so if you deal with them, go in with a polygraph under your arm.
