The question asked concerns emergency response to an oil spill for which the Department of Fisheries and Oceans (DFO) is the lead department. DFO is responsible for developing emergency procedures to deal with such disasters, through the Canadian Coast Guard (http://www.ccg-gcc.gc.ca/rser-ssie/er-ie/main_e.htm).
Transport Canada's role lies more with the prevention of such incidents through regulatory and inspection programs. Although we would not take the lead in a response to such a disaster, our expertise in ships and shipping matters makes us a critical resource department.
With respect to other departments, depending upon the size and location of such a spill, many agencies, departments and even other governments would be involved, as established in national and regional contingency plans. However, DFO is the lead department for these initiatives.
On the responsibility for ensuring that adequate resources are available, this also falls with the Department of Fisheries and Oceans. Their last report to Parliament on this issue should be of interest (http://www.ccg-gcc.gc.ca/rser-ssie/er-ie/rtp/main_e.htm).
