I'm a Canadian citizen, my wife was waiting for sponsorship during covid, my 2 kids were born outside and got automatic citizenship while in foreign country because of me being citizen. My wife and kids finally came to canada in November. 2021, .my question is how does CCB will be calculated? From the day they were born in different country or the day my wife became PR, started living in canada with kids? Meanwhile I'm citizen and been working in Canada paying taxes. Please explain briefly, as I'm confused.
