Where and how to renew 3-star HK ID card issued in 1989 in HongKong?

My name is Chan, Yuk-Lan. I am born in Hong Kong. Now living in Montreal. I have a 3-star HK ID card issued in 1989. I want to renew it. Could I do it at the Chinese Consulate in Montreal? Could I apply HK ID card for my children also at this consulate? They are not born in HongKong though. Thank you.
