It's official. Ted Cruz is no longer Canadian. Not even a little.

The Texas senator, who was born in Canada and had dual citizenship with the U.S., has officially renounced his Canadian dual citizenship , a spokesperson for Cruz confirmed today.

Cruz's office provided ABC News with a copy of the Canadian Renunciation Letter, which says he formally renounced his Canadian citizenship on May 14, 2014. The letter, which is signed by a Canadian minister (unclear who), was opened at Cruz's home in Houston today.

The letter simply reads, "the person named above has formally renounced Canadian citizenship and pursuant to the Citizenship Act will cease to be a citizen." The date listed on the letter was May 14.

Cruz, who is floated as a potential presidential contender in 2016, discovered he held dual Canadian and U.S. citizenship last year when it was first reported by the Dallas Morning News, and questions were raised about his eligibility to run for president. Cruz said last August that he would renounce his Canadian citizenship.

"Nothing against Canada, but I'm an American by birth and, as a U.S. senator, I believe I should be only an American," the Texas Republican said in a statement in August.
