I loaned a friend approx. $35,000 over a period from Jan 2005 to 2006. She and her husband signed an IOU to me to pay back this money. I have been waiting for them to start paying back but a series of financial set backs and excuses I have yet to be paid even a payment. Can I still sue them to pay back or is it to late

Where? It varies by State and Country.

In Ontario, Canada

The Statute is two years from the last loan or payment.
