ESQUIMALT, B.C. - Two sailors suffered minor injuries after a Canadian submarine struck bottom during weekend training exercises off Vancouver Island.

HMCS Corner Brook was conducting submerging manoeuvres Saturday in the vicinity of Nootka Sound, off the west coast of Vancouver Island, at the time.

Pash said the 60-person crew immediately brought the ship to the surface to conduct safety checks.

Two sailors suffered bruises.

Pash said no fuel was released into the environment, and Corner Brook was returning Sunday to Canadian Forces Base Esquimalt, near Victoria.

He said the crew was participating in advanced officer training at the time.

"The type of training is actually amongst the most challenging conducted in submarines, focused on developing the skills of potential submarine commanding officers," Pash said in an interview Sunday.

The navy will investigate what happened.
