how do I make my USA-born children citizen of Canada from Canadian citizen parents not born in Canada?

Posted October 19th, 2010 by immigratecanada and filed in Immigration to Canada

Both my wife and I obtained about 14 years ago our canadian citizenship through naturalization. Our children from 2 to 6 are born in the USA where we live.
How can they become citizen of Canada?
thank you for your help.
