A year later, in August 2002, he took employment with the
Prime Minister's Office as
Jean Chrétien's director of communications, often acting as the Prime Minister's spokesman. On December 10, 2003, two days before retiring from office, Chrétien appointed Munson to the
Senate of Canada where he served as the Whip of the Senate Liberal Caucus from 2008 to 2016. Munson represents the province of Ontario in the Senate with his official designation including the region known as Ottawa-Rideau Canal. Munson has not claimed a Senate housing allowance since it started in 2010 to post its expenses on the Internet. His primary residence is in the
National Capital Region. On January 29, 2014, Liberal Party leader
Justin Trudeau announced all Liberal Senators, including Munson, were removed from the Liberal caucus, and would continue sitting as Independents. The Senators refer to themselves as the
Senate Liberal Caucus even though they are no longer members of the parliamentary Liberal caucus. 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, Senator
Joseph 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 this senator. Munson retired from the Senate on July 14, 2021, his 75th birthday. ==References==
