Minister of National Defence

As Minister of Defence, Collenette oversaw the reorganization, restructuring and re-engineering of the department as part of the federal government's deficit cutting. During this time the Canadian Forces were involved in challenging assignments in the Balkans, Haiti and Somalia.^{[citation needed]}

During his tenure, Collenette was at the centre of the controversy over the establishment of a public inquiry into the Somalia Affair investigating war crimes committed by Canadian Soldiers during deployment in 1992 by the Mulroney Progressive Conservatives. The Chrétien government later decided to curtail the inquiry.^{[citation needed]}

In October 1996, Collenette resigned from cabinet citing a letter that he had written on behalf of a constituent. An access to information request revealed Collenette broke ethical guidelines by writing the letter to the Immigration and Refugee Board.^[2] Collenette cited this violation as his official reason for resigning from cabinet but his resignation also served to remove him from the ongoing Somalia Affair controversy.^[2][3]

Minister of Transport

After a few months on the back benches, he was re-admitted to Cabinet in July 1997 and was appointed Minister of Transport. In this portfolio his most important decisions were those that led to the merging of Canadian Airlines and Air Canada, the divestment of CN Rail operations in Northern Manitoba to the favour of Omnitrax, and the pseudo-commercialisation of Port Authorities under the Canada Marine Act.^{[citation needed]} He also successfully argued in the late 1990s for the first substantial increase in funding for Via Rail since cuts in 1981, 1990 and 1994.

On 11 September 2001, the Federal Aviation Administration (FAA) closed down U.S. airspace after a series of terrorist attacks on the World Trade Center and the Pentagon. Collenette acted swiftly and shut down Canadian airspace in order to take in diverted U.S.-bound international flights, launching Transport Canada's Operation Yellow Ribbon. Ultimately, 255 flights carrying 44,519 passengers were diverted to 15 Canadian airports^{[citation needed]}. In the time that has followed, Collenette has applauded the way Canadians responded to the crisis. He, Chrétien, U.S. Ambassador to Canada Paul Cellucci, and other provincial and local officials presided over Canada's memorial service to mark the first anniversary of 9/11 at Gander International Airport in Newfoundland and Labrador. There, he helped Chrétien unveil a plaque, commemorating the acts of kindness seen for the diverted passengers not just in Gander, but across the country.

Regional Minister Responsible for the Greater Toronto Area

As regional Minister for the Greater Toronto Area 1997–2003, Mr. Collenette oversaw federal infrastructure funding that resulted in the largest single expansion of cultural institutions in Canadian history at the Royal Ontario Museum, the Art Gallery of Ontario, the Four Seasons Centre for the Performing Arts, the National Ballet School, the Royal Conservatory of Music, the Roy Thompson Hall and the Gardiner Museum of Ceramic Art. He also initiated the second tranche of GTA infrastructure funding for $1 billion towards major GO Transit improvements, including the reopening of CN Bradford to Barrie line. Mr. Collenette promoted the concept of a rail link between Pearson Airport and downtown Toronto and under his leadership, planning, acquisition of property and a Solicitation of Interest the project was implemented. The highly successful link was subsequently built by Metrolinx and opened in 2016.

Collenette also designated the Oak Ridges Moraine portion of the Pickering Airport lands administered by Transport Canada, as open greenspace in perpetuity. These lands eventually became part of the Rouge National Urban Park, opened in 2015.

Retirement

Chrétien was pressured into resigning as prime minister and party leader by supporters of former finance minister Paul Martin. As Collenette was considered a staunch Chrétien loyalist it was not surprising that he was dropped from cabinet when Martin became prime minister in December 2003. Collenette initially planned to stay on as a backbench MP, however he was then informed that his riding nomination would not be guaranteed. On 29 January 2004, Collenette announced his retirement from politics and went on to work in academia and as a consultant in the private sector.

City of Ottawa Transportation Task Force Committee

On 19 January 2007, Ottawa Mayor Larry O'Brien named Collenette as the head of a volunteer Transportation Task Force Committee in which in a six-month period it reviewed the transportation issues across the city. It produced a report which suggested light-rail service expansion throughout the city of Ottawa, including an east–west route in a downtown tunnel, and several communities in Eastern Ontario as well as portions of the Outaouais region in Western Quebec. The Ottawa LRT opened in 2019. His report also suggested one to two new interprovincial bridge crossings between Gatineau and Ottawa over the next 30 years.^[5][6]
