This story appears here as we are often asked the question, "Do ghosts haunt the shipwreck of their ships?" According to the following report which I found at About.Com and of course, Fredrick Stonehouse's book, Haunted Lakes, it seems that this might indeed be the case.
Although nearer to the states than Canada, The Emperor is in the great lakes... literally. She sank taking twelve men to a cold and watery death in Lake Superior in 1947. The ship is/was a large steel ore steamer and is a favourite haunt of divers... and of possible ghosts.
One diver reported on swimming into a crew cabin to find the apparition of a sailor laying peacefully on his bunk. The 'ghost' seemed to look blankly at the diver, according to Stonehouse, before the diver had seen enough and quickly returned to the surface.
On other occasions, divers have reported hearing the engine sounds of the ship despite the boilers and works being underwater for many years. Another reported hearing a metallic voice saying the word "Die!" not once, but twice! One poor diver even came upon what can only be described as the ghost of possible one of the engine crew. Once making "eye" contact, (the exact quote from the book is "The eyes were dark pools of nothing, really just black holes, but still they asked the silent questions, 'Why me? Where are my friends? Why am I alone?'") the spectre seemed to go back about checking the equipment in the engine room seemingly unaware of the covering of dirt and muck brought on to it by the lake.
