Typo (Error) in Family Information Form

[rea11]

Hi there,

I'm planning to apply for my parents visitor visa. I'm a Canadian citizen.
While going through the old forms, I realized that there was a typo in date of birth for one of my siblings.

My brother's date of birth is year 1990 but on the form I entered by mistake 1992.

Now, I want to apply for my parents visitor visa and want to get this corrected. How can I get this typo corrected. Can anyone please advise.

Thank you
