I have also problem with Netfile to Quebec. I receive following error message:
Based on our information, your situation on December 31, 2012, is different from your situation in 2011. You must therefore enter the date of the change on line 13. This information is important as it is communicated to other government bodies (for example, to the Régie des rentes du Québec to determine the child assistance payment, and to the Ministère de l'Éducation, du Loisir et du Sport to calculate loans and bursaries for students).
I provided all the info regading the change during the interview phase but I don't see this info reflected in the result file (PDF). Support doesn't answer my emails. What can i do?
