Capt. Peter Ryan says the fire broke out at 10:52 a.m. on the warship's return trip to Halifax after a six week mission in the Caribbean.
The fire happened in waters near the Carolinas.
Ryan says sailors were able to put out the flames using fire extinguishers.
He says all 36 crew members are unharmed and the ship doesn't require any assistance.
Ryan says while all fires are serious, this was not comparable to the recent fire on HMCS Protecteur that burned for several hours.
HMCS Kingston and Glace Bay, also part of the mission, are still scheduled to arrive in Halifax on Wednesday.
Ryan says they're looking into what caused the fire.
