Arthur Wentworth Roebuck, QC ,(February 28,1878 –November 17,1971) was a Canadian politician and labour lawyer.
Roebuck was born in Hamilton,Ontario in 1878 and grew up on a farm in Wellington County,near Guelph. He worked as a reporter for the Toronto Daily Star and in 1905 became owner/editor of the Temiskaming Herald in New Liskeard and the Cobalt Citizen. He sold them in 1915 when he left to study law,graduating from Osgoode Hall after three years. In 1918 he married Inez Perry and together they raised one daughter. 
Roebuck ran a Liberal candidate in Temiskaming in the 1911 Ontario general election| and the 1914 Ontario general election| but failed to get elected. He also ran in the 1917 federal election. He was involved with the United Farmers of Ontario and its successor,the Progressive Party,in the 1920s before rejoining the Liberals.  He finally won a seat in the Legislative Assembly of Ontario in the 1934 provincial election that brought the Ontario Liberal Party led by Mitchell Hepburn to power. 
Roebuck was a senior figure in the Hepburn government serving as Attorney-General of Ontario from 1934 to 1937 as well as Minister of Labour from 1934 until 1935. A progressive,Roebuck promoted the rights of Jews against the anti-Semitism that was still prevalent in 1930s Ontario,and defended the rights of trade unions. He broke with Hepburn over the government's handling of the 1937 United Auto Workers strike against General Motors in Oshawa,and resigned in protest with fellow minister David Croll. Roebuck remained as the Liberal Member of the Legislative Assembly for the Toronto riding of Bellwoods until 1940.
He attempted to return to provincial politics running for the leadership of the Ontario Liberal Party at its 1943 leadership convention to succeed Hepburn,but finished second to Harry Nixon.
Roebuck ran for a seat in the House of Commons of Canada in the 1917 federal election as a Laurier Liberal,but was defeated.
Re-entering federal politics,Roebuck was elected Liberal Member of Parliament for the Toronto riding of Trinity in the 1940 federal election after successfully challenging sitting Liberal MP Hugh Plaxton for the party's nomination. 
In 1945,he was appointed to the Senate of Canada by Prime Minister William Lyon Mackenzie King,and remained in the Upper House until his death. At the outset of his appointment,he worked with the Canadian Jewish Congress and Rabbi Avraham Aharon Price to have young,Jewish refugees released from internment camps to study in Toronto.
He was an important figure in the civil liberties movement in Canada following the war. Following the Igor Gouzenko Affair,Roebuck opposed the government's suspension of the individual rights of individuals accused of espionage,and criticized the use of the Royal Commission on Espionage's transcripts in court. Later,he participated in the defence of Israel Halperin,one of the accused spies,and chaired the Senate Committee on Human Rights and Fundamental Freedoms in 1950,advocating the creation of a Canadian Bill of Rights.
Roebuck opposed Pierre Elliott Trudeau's Senate reform proposal in 1969. 
There are Arthur Wentworth Roebuck fonds at the Archives of Ontario  and Library and Archives Canada. 
Mitchell Frederick Hepburn was the 11th premier of Ontario,from 1934 to 1942. He was the youngest premier in Ontario history,becoming premier at age 37. He was the only Ontario Liberal Party leader in the 20th century to lead his party to two majorities.
There have been various groups in Canada that have nominated candidates under the label Labour Party or Independent Labour Party,or other variations from the 1870s until the 1960s. These were usually local or provincial groups using the Labour Party or Independent Labour Party name,backed by local labour councils made up of many union locals in a particular city,or individual trade unions. There was an attempt to create a national Canadian Labour Party in the late 1910s and in the 1920s,but these were only partly successful.

Liberal-Progressive was a label used by a number of candidates in Canadian elections between 1925 and 1953. In federal and Ontario politics,there was no Liberal-Progressive party:it was an alliance between two parties. In Manitoba,a party existed with this name.
