Hello everyone...I am putting together my forms to sponsor my husband and came across this question like many of you. I eventually called a lawyer who informed me that I don't have to provide proof of income for the past 12 months as long as I fill out the form (Sponsor Questionnaire Imm 5540 question #7): Starting with your current employer, if applicable, give details of all employers you have worked with over the past five years...to be sure, I re-read the guide and called cic to confirm.
How to apply to sponsor
If you live in a province or territory other than Quebec or are living exclusively outside of Canada and intend to live in a province or territory other than Quebec upon your return, you must complete the following forms:
*the Application to Sponsor and Undertaking (Imm 1344A);
*the Sponsorship Evaluation (Imm 1344B; must also be signed by the person you want to sponsor). See instructions on how to complete the Sponsorhip Agreement for more details;
*the Sponsorship Evaluation (Imm 5481);
if the person you are sponsoring is your spouse, common-law partner or conjugal partner and he or she has dependent children, you will have to complete the financial evaluation form instead. To obtain this form contact our call centre and ask for kit Imm 5482 or download it from our web site.
...
but if you check their site and look up Imm5482 and read the guide it tells you if you are a Quebec resident to not complete this form
I hope this helps someone, good luck to all!!!
