Lord Dufferin involved himself as much as was permissible in Canadian politics, even going so far as to advise ministers to abandon policies which he thought mistaken. He followed proceedings in the Parliament with interest, although as the Queen's representative he was barred from entering the House of Commons. He established an Office of the Governor General in a wing of the Parliament buildings, and Lady Dufferin attended many debates and reported back to him. In 1873, the Pacific scandal arose when the Conservative government of John A. Macdonald was accused by the Liberal opposition of financial impropriety in relation to the construction of the Canadian Pacific Railway. Dufferin prorogued parliament, and established an enquiry which found against the Government, and Macdonald fell from power.
