Received an email from CIC that :
IMM 5669 (for Principal Applicant): The Schedule A (IMM 5669) is missing a handwritten signature. Although the current form states that an electronic signature is acceptable, due to legislation changes as of May 22nd, 2018, a handwritten signature is required for this form. Please provide a newly completed Schedule A (IMM 5669) and ensure that you sign the form by hand once printed.
Note: For question 6 in the Schedule A, if you have not worked in the past 10 years (e.g. you’re retired), you must provide details of your personal history since the age of 18.
I have 2 options, send updated form by mail or e-mail which I will email the scanned form.
