Changes to the "Canada Shipping Act" in 1961 and the formation of the Canadian Coast Guard in 1962 saw the Department of Transport, which had responsibility for the CCG from 1962-1995, given responsibility for maritime search and rescue in support of the Minister of National Defence's mandate. As a result, the Minister of Transport designated "marine rescue controllers" who were CCG personnel that would work within the RCAF's rescue co-ordination centres. The RCCs were renamed joint rescue coordination centres (JRCCs) to denote the dual role of aeronautical and maritime search and rescue, as well as their joint operation by RCAF and CCG personnel.
