Father has old citizenship card (credit card size) issued in 2002 and will apply e-certificate. The fee shown is $75. On CIT0001E form first two options need to be selected. 1) I need to replace my citizenship card. 2) I need to pass down my Canadian citizenship to my child born abroad. When we check applicable fee on IRCC website drop-down list it is confusing. It shows $530+$100 ($630) for each citizenship application abroad (in Pakistan) for person above 18 years. Since the children ages are 26, 28, 33, 35 will the fee be $630 per child for citizenship certificate or just $75 each as they're already Canadian from one parent. Thanks for help.
It's important to be clear that they are not applying for 'citizenship' but a certificate of citizenship, so $75 each. (Difference is that they are citizens by descent - i.e. from birth - so they are not applying for a grant of citizenship. They're applying to prove that they are citizens. )
I don't know how easily this links to the payment system (i.e. whether it will show the right amount).
But note: each of the children (adults) should be filling out one of these forms, separately. (If the father wants to replace his citizenship certificate - card style - with the new electronic one, that's fine - another separate app).
They should each (except for father) be selecting the option "I never had a citizenship certificate and I was born outside Canada to a Canadian parent who was born in Canada or naturalized in Canada before I was born; I wasn’t adopted by my Canadian parent"
The father should indeed choose 'I need to replace ... '.
The selection 'I want to pass down my Cdn citizenship to child born abroad' is for parents applying on behalf of minors.
You may want to check in the citizenship sub-forum here- I'm pretty sure this is correct but do check.
Separate q/comment: do you know how soon/how quickly each of the children want/need to get the Canadian passport? If they want to apply soonest they should keep a copy of this application. After that they can check with high commission if it's possible (and under what circumstances) to get temporary passport - keep in mind they may refuse to do so unless travel reasons are urgent or with other restrictions.
