Is a child born in Canada with both parents Canadians who were adopted at one year by a USA couple a Canadian citizen?

Good question. At one time the USA supported Dual Citizenship but not anymore. I was born in West Germany by American parents and have this designation. I would speak to the Canadian consulate and ask about this. I would think that a child born in Canada would be a Canadian citizen irregardless of the fact they were adopted. Same goes for illegal aliens in the US. They may be here illegally yet if their child is born in the states becomes an automatic US citizen.
