Incorrect information in siblings birth certificate

[dontaelike]

Hi,

I am applying for express entry and mentioning all the information related to my siblings as required (doing it via a law firm). My sibling is also planning to apply a few years down the line, in his birth certificate my fathers date of birth is incorrect and we are unable to change it (this information is requested in Schedule A and also it will be requested when they asks if he has a sibling in Canada)

Will this be a problem for him or me later when he applies for PR if he plans to do so?

Thanks,
