Can You Avoid Student Debt By Moving to Canada?

I was hoping someone could provide me with resources or advice about avoiding my student debt repayment since I have permanently relocated to Canada. I have read conflicting information online about whether collection agencies have made financial arrangements with Canadian banks to automatically withdraw delinquent funds. I have also had a very hard time finding lawyers or financial advisors with expertise on this question. I do not plan on returning to the U.S. What would be the potential consequences if I stopped paying back my loan?
