The RIMPAC exercises are over for the 35 to 40 crew members of the Canadian ship HMCS Whitehorse.
Sailors from the ship were caught behaving badly, so they were ordered to leave the RIMPAC exercises in California and return to Canada.
One sailor was even reportedly arrested by San Diego police.
The United States Navy has launched an investigation into the incidents.
Vice Admiral Mark Norman, Commander of the Royal Canadian Navy issued the following statement:
"The men and women in our Royal Canadian Navy set a high standard of conduct when representing our country at home and abroad. While instances have arisen that have fallen short of these standards, the vast majority of our personnel serve with distinction and professionalism."
