If you believe you may have qualified for assistance in recent years but didn’t make application, Regular Premium Assistance may be provided retroactively to a maximum of six years from the date on which a request is received. If it appears you are eligible, you will need to provide photocopies of Notices of Assessment/Re-Assessment from the Canada Revenue Agency which show your net income for the relevant tax years. If you are married or living in a marriage-like relationship, photocopies of your spouse’s Notices of Assessment/Re-Assessment will also be required.
