The Trump hotel in Toronto is one of 14 Trump properties impacted by a security breach involving guest information, including payment card data.
Hackers were able to compromised the systems of Sabre Hospitality Solutions, a reservation booking service used by Trump Hotels, but did not affect the Trump Hotels' systems.
Hackers gained access to credit cards and other information from guests at 14 Trump organization properties in 2016 and had unfettered access to the information for months, the organization reported Tuesday.
In some cases, hackers also gained access to guest names, email, phone numbers, addresses, and other information, although the company reported that Social Security numbers and passports were not accessed.
Just last September, Trump's hotels agreed to settle the penalties worth $50,000 aftera series of alleged security breaches compromised payment information to the tune of 70,000 cards, which was said to be accessed in May 2014.
While being hacked is nothing new to Trump Hotels, it is far from the only hotel group affected in the latest breach.
While this incident may fall primarily on the company behind the reservations systems, Trump Hotel guests are not new to data breaches.
The hack is the third time a months-long security snafu has affected guests of the chain of luxury hotels.
The statement continued: "We are working with Sabre to address this issue".
Trump International Hotels Management later agreed to pay up $50,000 to settle with NY state over the data breaches, which resulted in the theft of 70,000 credit card numbers and 300 Social Security numbers.
'Then you look at Trump's hotels, and they're obviously a highly symbolic target'. What is known, however, is that more and more hospitality chains are now announcing that customers have been impacted and the breach of their consumers' personal financial information is damaging to both the customers and to the brands they've come to trust.
ProPublica and Gizmodo found that a number of Trump properties, including the Mar-a-Lago resort in Palm Beach, Florida - where the president regularly spends his weekends, and he has hosted foreign heads of state - had less-than-secure wireless networks.
