Capt. Peter Ryan, with JRCC, said the call for help came in around 4 a.m. Sunday.
The four crew of the F.V. Gentle Lady climbed into a life raft after running into trouble off the coast of Nova Scotia, said Ryan.
JRCC coordinated the rescue with another nearby fishing vessel, the Ocean Concord.
The rescued crew are all safe and are currently steaming towards Louisbourg aboard the Ocean Concord and will be transferred to a Canadian Coast Guard Vessel.
The rescue centre were about to send a Cormorant helicopter and a Hercules plane out to the site but those were cancelled, thanks to help form the Ocean Concord.
