As part of Operation Caribbe, "Whitehorse" deployed to the eastern Pacific Ocean with sister ship, in February 2014. In June 2014, "Whitehorse" took part in the RIMPAC 2014 naval exercises off southern California. However, she was ordered to return home after allegations of misconduct, including sexual misconduct, occurred while docked in San Diego. "Whitehorse" is the first Canadian warship to be withdrawn from an exercise due to "reasons of conduct". The incident contributed to the imposition of tighter restrictions on the availability of alcohol on board Royal Canadian Navy warships which were announced in December 2014.
