A beauty queen was left devastated a day after winning the crown for Miss Universe Canada.

Denise Garrido won the crown for the competition but quickly had it stripped from her as officials admitted that they made a mathematical mistake while counting their votes.

The winner is actually Riza Santos, from Calgary, Alberta, and Garrido actually landed in third place at Sunday's competition.

"During the validation of the computerized scoring results (which occurs the following day), a typo was discovered in the top five entries, which significantly impacted the final results of the competition," pageant director Denis Davila said, according to ' the Toronto Sun. "This is the first instance of this type of error in the 11 years that Beauties of Canada (BOC) has produced the Miss Universe Canada pageant. This is an unfortunate circumstance where a human error was made, and in such a situation, as difficult as it is, it is only right to correct the error."

The title has been transferred from Garrido, who is a biomedical sciences graduate, to Santos.

Davila has issued an apology to Garrido for the mishap.

Santos, 26, previously served in the armed forces as a teenager and enrolled in the Canadian Forces Army Reserv with 15 Field Ambulance.
