He was born in Calgary. His mother was a US citizen and his father was from Cuba. His father was sent to Canada for a short time by his job. The question is what is a natural born citizen, something the courts have never answered. He was given a Canadian birth certificate and citizenship. He's since renounced that citizenship saying he didn't know he even had it since they left Canada when he was very young.
Its important to note that his circumstances are almost identical to Obama's. His mother was a US citizen and he was born in a foreign country (assuming Obama was really born in Kenya). If Cruz is eligible for the presidency because of his mother's citizenship, then so is Obama.
