The answer is as follows:
a) In the event of a pollution incident such as the one off the coast of Spain, the Canadian Coast Guard (CCG) would activate the national response team (NRT), and mobilize all government and industry resources to the impacted area. Should further resources be required, the CCG would call upon its international partners. This response would be conducted in accordance with national, regional and area marine oil spill contingency plans.
b) The CCG, Department of Fisheries and Oceans (DFO), is the lead federal agency responsible for Canada's oil spill preparedness and response and thus, would lead a response to such an incident.
c) Other government departments may provide assistance to DFO in the event of a pollution incident. These include Environment Canada, who may provide scientific and environmental advice related to shoreline and on-water cleanup operations; Transport Canada, who may provide advice related to the operations and safety of vessels; and the Department of National Defence, who may be called upon to provide personnel or specific logistical assistance.
d) Canada's marine oil spill preparedness and response regime is built upon an essential partnership between government and industry. Canada has four commercial response organizations certified by the CCG to each provide a 10,000 tonnes response capability. In addition, CCG has an inventory of approximately $74 million worth of pollution response equipment located across the country for offshore spills, spills in the Arctic (waters north of 60° latitude) and as a safety net for the industry's capacity. Furthermore, Canada, along with 66 other nations, is signatory to the international convention on oil pollution preparedness, response and co-operation (OPRC). As such, Canada may call upon the other 66 signatories for assistance. In the event of a pollution incident occurring in the contiguous waters between Canada and the U.S., a joint response would be conducted in accordance with the joint marine pollution contingency plan. Canada has a similar agreement with Denmark for the contiguous waters between Canada and Greenland.
