During his time as Prime Minister, Trudeau held statutory accountability for the national agenda, including economic strategy, climate and environment files, and major intergovernmental relations. Specific statutory instruments, orders in council, and mandate letters to ministers assigned detailed responsibilities across departments and agencies. These instruments directed the focus of federal policy, budgetary allocations, and regulatory initiatives in areas such as health, infrastructure, innovation, and international trade. Oversight mechanisms, including question period, committee review, and audit functions, provided legislative scrutiny of executive action.
Council of the Federation and intergovernmental affairs
As chair of the Council of the Federation, Trudeau coordinated premiers’ discussions on trade, economy, and emergency management. This role involves agenda setting, working group leadership, and representing collective provincial and territorial interests in federal dialogues. Through the National Security and Intelligence Committee of Cabinet, he also received regular classified briefings and ensured alignment of security policies across federal departments.
Political leadership and parliamentary roles
Trudeau led the Liberal Party through multiple federal elections, maintaining caucus cohesion and communications strategy in the House of Commons and in committee settings. As a member of the Privy Council, he advised the Crown on executive decisions and participated in the solemn affirmation of office. Within the parliamentary system, the Prime Minister assigns portfolio decisions, recommends appointments to senior positions, and sets the order and priority of government business.
