HMCS Somers Isles was a temporary training facility and stone frigate for the Royal Canadian Navy (RCN) in Bermuda from 1944 to 1945 during the Second World War.
Beginning in mid-1944, work-up training for naval ships stationed on the East Coast of Canada took place in Bermudian waters as it allowed for training year-round compared to the RCN's previous work-up site, St. Margaret's Bay and Pictou, Nova Scotia.
It was originally built for the use of the Royal Navy, and was named for the prison hulks moored there by the Admiralty to house convict labourers.
The existing location, in St. Margaret's Bay and Pictou, Nova Scotia where the heavy weather in winter affected training.
