[1] and forms the nucleus of Canadian Coast Guard Station Sambro (CCG Station Sambro) which maintains a crew of four personnel on duty 24 hours per day (two shifts) who are expected to be underway within 30 minutes of being tasked on a search and rescue (SAR) mission by Joint Rescue Coordination Centre Halifax.

[1] On March 21, 2001, CCGS Sambro, CCGS Earl Grey, CFAV Firebird, HMCS Moncton, HMCS Goose Bay, CCGS Sir William Alexander and the commercial oceangoing salvage tug Ryan Leet tried to render assistance to the container ship Kitano which had caught fire off Chebucto Head, Nova Scotia.

CCGS Sambro was the first SAR asset to respond to reports of a commercial airliner crash at the mouth of St. Margaret's Bay on the evening of September 2, 1998.

There were no survivors among the 229 people on board Swissair Flight 111 and CCGS Sambro returned to normal SAR standby after other CCG and Canadian Forces assets took over search and recovery operations.

On September 17, 2008, Fireboat 08-448B capsized in Halifax harbour, while undergoing her acceptance trials and crew familiarization.
