I would send using email and attach LOE explaining the reason.Hi there,
I've received a letter from IRCC and asked to update IMM5669 for my father due to some typos and send back via email or mail. While I was doing IMM5669 form, I also found out some other mistakes on the form for both my parents (so two separate IMM5669). Can I correct them both and send back to IRCC using the email option? Or I just correct and send what they asked me to correct and use webform to correct the rest? Thanks
