Day was appointed to the Senate of Canada from New Brunswick in 2001. He has been active on issues of Veterans Affairs Canada and media concentration. He is scheduled to retire as a Senator on January 24, 2020 upon reaching the mandatory retirement age of 75. On January 29, 2014, Liberal Party leaderJustin Trudeau announced all Liberal Senators, including Day, were removed from the Liberal caucus, and would continue sitting as Independents. According to Senate Opposition leader James Cowan, the Senators will still refer to themselves as Liberals even if they are no longer members of the parliamentary Liberal caucus. Day was elected leader of the Senate Liberal Caucus on June 15, 2016. With the Senate Liberal Caucus facing losing official parliamentary caucus status in 2020 with a third of its caucus facing mandatory retirements on their turning age 75, Day announced that the Senate Liberal Caucus had been dissolved and a new Progressive Senate Group formed in its wake, with the entire membership joining the new group, including Day, who was announced as the interim leader of the new group. With Day's mandatory retirement in January 2020, on December 12, 2019, Nova Scotia senator Jane Cordy tweeted that her colleagues in the Progressive Senate Group had selected her as the new leader, ostensibly effective that same date. Additionally, she subsequently announced later that day Senator Terry Mercer would be moving into the whip/caucus chair role, that Senator would be become the new deputy leader, and that the interim monikers were being removed at the same time. On the eve of his pending retirement from the Senate, Day tweeted, "On the eve of my retirement from the @SenateCA, I would like to share my farewell remarks. It has been an honour to serve my fellow New Brunswickers and all Canadians. Watch my speech here: #SenCA #cdnpoli #nbpoli." He retired from the Senate on January 24, 2020, upon reaching the mandatory retirement age of 75.
