Ok, so the CIC web-site says:
You may not be eligible to be a sponsor if you:
•failed to provide financial support you agreed to when you signed a sponsorship agreement to sponsor another relative in the past
•defaulted on a court-ordered support order, such as alimony or child support
•receive government financial assistance for reasons other than a disability
. . . etc, etc
Perhaps key emphasis on the word "may", not sure how long this will impact your eligibility. I'll defer to another member with more hands=on experience with that.
