During this time, Allmand, who was the chair of the Parliamentary Friends of Tibet, hosted the 14th Dalai Lama's first visit to Canada in 1990. In 1995, he gained notoriety for voting against Minister of Finance Paul Martin's budget, as he was opposed to spending cuts that were deeper than promised during the 1993 election and because it did not cancel the Goods and Services Tax. As a result, Prime Minister Jean Chrétien removed him from his position as chair of the House of Commons Standing Committee on Justice, a position he held from January 17, 1994 to February 2, 1996, although he remained in the Liberal caucus. Allmand said that Martin's budget cuts "broke traditional Liberal principles" and his willingness to vote against his own party's majority government emboldened other Liberal MPs to follow suit, such as John Nunziata and Dennis Mills. He retired before the 1997 election after Chrétien appointed him president of the Montreal-based International Centre for Human Rights and Democratic Development (later renamed Rights and Democracy) to replace Ed Broadbent, its first president. Allmand served as the president of the International Centre for Human Rights and Democratic Development from 1997 to 2002. During the 3rd Summit of the Americas, held in Quebec City in 2001, Allmand encouraged social activists boycotting the event to speak with governmental actors in order to collaboratively develop better policy. During his time at the centre, Allmand supported the work done on the International Declaration on the Rights of Indigenous People. In the leadup to the signing of the Good Friday Agreement, Allmand was an active participant in the negotiations via the Coalition for Peace in Ireland. During the negotiations, Allmand met Rosemary Nolan, whom he married in 2002. He also served as the international president of Parliamentarians for Global Action. In 2004, Allmand was elected President of the World Federalist Movement–Canada, a position he held until his terminal illness led to his replacement in August 2016 by Walter Dorn. Allmand also served as a director of the Newman Centre of Montreal and CANADEM. In 2004, Allmand taught at McGill University as a visiting scholar at the Institute of Canadian Studies. In 2005, Allmand served as counsel for the International Civil Liberties Monitoring Group during the Commission of Inquiry into the Actions of Canadian Officials in Relation to Maher Arar, and argued that Canada's national security agencies, especially the Royal Canadian Mounted Police, chose security over rights and were largely unaccountable when they did so. In November 2005, Allmand was elected to the Montreal city council seat as a member of the Union Montréal party to represent Loyola, in the Côte-des-Neiges–Notre-Dame-de-Grâce borough.
