Thank you Roger and Shibuya for your replies. Thanks for the help.
Hi,
I tried to reply your PM but your inbox is full below is the answer to your query.
If you already submitted the full documents then re-fill these forms and send to to CHC ASAP with a cover letter mentioning the typo mistake but if you havent send the form to visa office yet and only send to CIC then at the time of sending the full docs to visa office send with the correct information and mention it in your cover letter.'
Cheers
Saki
