Source-derived summary

Murray Cotterill (June 27, 1913 – February 23, 1995) was a Canadian trade union activist and organizer for the Co-operative Commonwealth Federation (CCF).

In the 1930s, Cotterill was one of the organisers of the Co-operative Commonwealth Youth Movement. In the 1940s he was a CCF municipal candidate in Toronto and, in 1942, ran for the leadership of the Ontario CCF, losing to Ted Jolliffe. He was also an aide to Charles Millard in organizing the Steel Workers Organizing Committee and was active in rooting out Communists in the fledgling Steelworkers union and was the union's public relations director for many years. Cotterill was also president of the Toronto Labour Council of the Canadian Congress of Labour (one of two labour councils in the city) in the late 1940s. He worked as a labour relations specialist for the Canadian Congress of Labour and its successor the Canadian Labour Congress and was for a time in the 1940s and 1950s the director of the CCL's national Political Action Committee, a position he used to encourage closer ties between the labour movement and the CCF. Cotterill was also the leading force in the OFL's Political Action Committee which helped create an informal alliance between the CCF and the labour movement that later led to the formation of the New Democratic Party as a formal CLC-CCF project.

In the 1963 provincial election he was the NDP's candidate in the suburban Toronto riding of Lakeshore losing to Progressive Conservative Alan Eagleson.

In late 1963, Cotterill was involved with what were described as "secret" negotiations with John Wintermeyer, outgoing leader of the Ontario Liberal Party and various federal Liberals in pursuit of co-operation between the two parties and even their eventual fusion. Cotterill was reportedly offered the vice-presidency of the Ontario Liberal Party but declined. The talks ended due to the opposition of Ontario NDP leader Donald C. MacDonald.

Editorial summary

This brief starts where responsible research should: with the source description of “Murray Cotterill” as canadian politician. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA useful biographical orientation record, particularly for establishing names, roles and a first chronology. The current lead gives the account dated anchors—1913, 1995, 1942, 1963—that can be checked directly. The linked authority record independently contributes the date 1913-06-27. The account is most persuasive where Murray, Cotterill and Canadian can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the people & ideas register because the source frames it as canadian politician. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

The entry’s evidential value lies in the named roles, institutions and publications that can be tested against primary documentation. The source revision retrieved here is dated Aug 24, 2026. The linked authority identifier is Q6939178. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1913, 1995, 1942 and 1963.

Critical limits

A concise life account rarely captures disputed attribution, private networks or the changing language used to describe a career. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
