Operation North Pacific Guard, a joint Canadian-US initiative, saw a Canadian Coast Guard ship, Sir Wilfred Laurier, patrol the North Pacific to enforce international fishing rules. The two-month operation covered 20,000 kilometres, inspecting 15 international vessels for illegal activities like shark finning, undeclared catches, and unmarked boats. It also enforced the new ban on Pacific salmon retention. Despite facing logistical challenges, the operation succeeded in documenting marine pollution and uncovering cases of illegal fishing, with a significant seizure of undersized Pacific saury. The Sir Wilfred Laurier's refit to use a greener fuel blend and its role in scientific research underscore its multifaceted capabilities in enforcement, environmental monitoring, and scientific exploration.
