On Tuesday, the senator's office passed along a "Certificate of Renunciation of Canadian Citizenship" that was issued last month by the Canadian government.

"This is to certify that the person named above has formally renounced Canadian citizenship and pursuant to the Citizenship Act will cease to be a citizen," the certificate reads above Cruz's full name, Rafael Edward Cruz. 

The certificate is dated May 14. The senator received the certificate through the mail Tuesday. The Dallas Morning News first reported the news. 

Cruz held dual citizenship because he was born in Alberta, Canada, to an American mother in 1970. Any person born to an American citizen is automatically granted U.S. citizenship, even if they are born outside the country.

However, Cruz was also granted citizenship in Canada, a fact he did not realize until the Dallas Morning News pointed it out last year. He immediately vowed to renounce the dual citizenship last August. 

"Nothing against Canada, but I’m an American by birth and as a U.S. senator I believe I should be only an American,” Cruz said at the time

Questions have been raised about whether he would be able to run for president, since he was born in Canada. He has expressed interest in a run and visited a number of early nominating states. Most legal scholars agree that the constitutional requirement that a president be natural born include Cruz's circumstances. 

Cruz retained council in December to file the paperwork, but in January some wondered why the reportedly quick process was taking so long. It has been 10 months since The Dallas Morning News first reported on his dual citizenship.
