Interim Leader (Canada)

An interim leader, in Canadian politics, is a party leader appointed by the party's legislative caucus or the party's executive to temporarily act as leader when a gap occurs between the resignation or death of a party leader and the election of their formal successor. Usually a party leader retains the leadership until a successor is formally chosen — however, in some situations this is not possible, and an interim leader is thus appointed by the party's caucus or the party executive. An interim leader may also be appointed while a leader is on a leave of absence due to poor health or some other reason, and then relinquish the position upon the leader's return.

An interim leader has all the rights and responsibilities of an elected party leader, with the exception that the person does not have the discretion to choose the timing of their departure — an interim leader serves only until the party organizes and holds a leadership convention. By virtue of lacking a mandate from the party membership, however, an interim leader is not generally seen as possessing the authority to truly put his or her own ideological and organizational stamp on the party, and is thus effectively limited to a caretaker role in most cases.

There have been a number of instances where instead of a competitive leadership race between multiple candidates, the leadership convention directly ratified the interim leader as the party's new permanent leader, but a convention must still take place in some form.

By convention, if a competitive leadership race between sitting members of the party's caucus is taking place, the interim leader should normally be a caucus member who is not standing as a candidate in the leadership race, so they do not gain unfair advantage in the contest. Only in rare cases, such as when a minor party's interim leader is also its only caucus member in the legislature or when no other caucus colleagues are competing for the leadership positions, will an interim leader stand as a candidate for permanent leadership.

An interim leader may, if necessary, lead the party into an election, but by Canadian custom, an election is usually not called while one of the parties is in a leadership race.

Practice

In most circumstances, a leader who has decided to step down gives extended notice, and a leadership convention is organized to choose their successor. The outgoing leader remains in the position for the duration of the leadership campaign, and then hands over power to the successor shortly after the convention.

However, sudden vacancies may occur for a variety of reasons.

Death in office

Wilfrid Laurier died in 1919, while holding the leadership of the Liberal Party. Daniel Duncan McKenzie was selected as the party's interim leader, serving until William Lyon Mackenzie King was selected as the party's leader later in the year.

Jack Layton initially took a leave of absence from the leadership of the New Democratic Party in 2011 for cancer treatment, and Nycole Turmel was named the interim leader of the party; Layton died before his intended date of return to office, and Turmel continued as interim leader pending the results of the 2012 leadership election.

Scandal

Glen Clark was forced to resign the leadership of the British Columbia New Democratic Party, and the premiership, after a criminal investigation against him was announced. He was succeeded by Dan Miller, who served until Ujjal Dosanjh won the resulting leadership convention.

Creation of a new party

In 2000, after the Reform Party was folded into the new Canadian Alliance, Deborah Grey served as the party's interim leader until the party's first leadership convention selected Stockwell Day. Similarly, after the Canadian Alliance and the Progressive Conservatives merged in 2003, Senator John Lynch-Staunton was named interim leader of the new Conservative Party until the first leadership convention selected Stephen Harper.

Internal dissension

In 1983, Joe Clark received only 66.9 per cent support in an internal leadership review process conducted by the Progressive Conservative Party. Feeling that he did not have sufficiently strong support within the party, he thus scheduled a leadership convention. Initially, he remained the party's leader in the meantime — however, as he was also standing as a candidate in the leadership process, he eventually stepped down and Erik Nielsen was installed as the party's interim leader.

In early 2002, Stockwell Day's leadership of the Canadian Alliance came under criticism due to party infighting. Like Clark, he thus announced a new leadership campaign in which he would reoffer as a candidate, and John Reynolds became the party's interim leader.

Leader defeated in an election

In several cases, a party's leader has been defeated in his or her own riding in an election, and has resigned soon afterward. A resignation is not necessarily required in such a scenario, as other leaders in the same situation have retained the leadership until they were able to run in a by-election. However, for personal or political reasons some leaders have opted to immediately resign the leadership instead.

Andy Brandt became interim leader of the Ontario Progressive Conservative Party following the party's defeat in the 1987 provincial election, in which leader Larry Grossman lost his own seat. He served until 1990, when he was succeeded by Mike Harris following a leadership convention.

Jean Charest became interim leader of the federal Progressive Conservatives following the party's defeat in the 1993 election, in which Kim Campbell lost her own seat. At the next leadership convention in 1995, Charest was acclaimed to the full leadership of the party. Additionally, having subsequently become leader of the Quebec Liberal Party, Charest resigned as leader following the party's defeat in the 2012 provincial election, in which he lost his seat. As a result, Jean-Marc Fournier was named interim leader.

Joy MacPhail served as interim leader of the New Democratic Party of British Columbia from 2001 to 2003, following the party's defeat in the 2001 provincial election, in which Ujjal Dosanjh lost his seat. She served until Carole James was selected as the party's new leader in 2003.

John Tory was defeated in the 2007 Ontario election, in which he ran in a different seat than the one where he was an incumbent. He stayed on as leader, despite facing some internal criticism — notably, a leadership review in 2008 gave him just 66.9 per cent support,"Conservative Leader John Tory to remain after 67 per cent in leadership vote"
— Canadian Press, February 23, 2008. the very same result which Joe Clark had deemed ''not'' sufficient to justify staying on as leader of the federal Progressive Conservatives in 1983. Bob Runciman served as interim parliamentary leader, but Tory retained the actual leadership of the party. Tory eventually resigned in 2009, after losing a by-election in Haliburton—Kawartha Lakes—Brock, and Runciman became the party's interim leader.

Bob Rae was named interim leader of the Liberal Party following the 2011 election, in which his party's previous leader, Michael Ignatieff, was defeated in his own riding.

Internal disorganization

In one case, Ontario Liberal Party interim leader W.E.N. Sinclair led his party through two consecutive elections in 1926 and 1929. He was interim leader from 1923 to 1930 since, due to the party's state of disorganization, there was no leadership convention held in that period to choose a successor to Wellington Hay. When a convention was finally held, Sinclair drew little support and withdrew before balloting began. He was succeeded by future Premier Mitchell Hepburn.

Leader accepts another position

Sometimes an outgoing leader decides to resign immediately in order to ensure party unity, because they have accepted an appointment or chosen to stand as a candidate for (or been elected to) another position.

Following the resignation of Daniel Johnson as leader of the Quebec Liberal Party in 1998, the prospect of Jean Charest becoming the party's new leader began to attract widespread public support. When Charest subsequently decided to stand as a candidate, he resigned as leader of the federal Progressive Conservatives, and Elsie Wayne became the party's interim leader.

Similarly, Thomas Kennedy served as interim leader of the Progressive Conservative Party of Ontario from 1948 to 1949, after George Drew resigned to contest the leadership of the federal Progressive Conservatives.

Leave of absence

From November 1954 to February 1955 William Earl Rowe acted as interim Leader of the Opposition when Progressive Conservative leader George A. Drew was in poor health following an attack of meningitis. Drew returned but later fell ill again, and Rowe again became as interim leader of the opposition in August 1956. Drew resigned in September and Rowe became interim party and opposition leader until December, when John Diefenbaker was elected party leader.

An interim leader, Nycole Turmel was appointed to lead the NDP on July 28, 2011, while Jack Layton was on a medical leave of absence to fight cancer. She continued in the position following Layton's death on August 22, 2011.

Political circumstances

Following the 2008–2009 Canadian parliamentary dispute, Stéphane Dion's continued leadership of the federal Liberals was felt to be an impediment to the party's popular support, but with a situation where the party had to be almost immediately prepared to either take over the government or face an election, many party members felt that the party did not have the time to go through a conventional leadership race. After some internal debate, leadership candidates Dominic LeBlanc and Bob Rae withdrew from the race, and the only remaining candidate, Michael Ignatieff, was immediately named interim leader. His leadership was formally ratified at a party convention in May 2009.

Personal circumstances

Pam Barrett resigned the leadership of the Alberta New Democrats in 2000, but for health reasons she opted not to retain the leadership until her successor could be chosen, instead announcing that her resignation was effective immediately. Raj Pannu was named interim leader, and was then acclaimed leader at the subsequent convention. Brian Mason, who succeeded Pannu to the leadership in 2004, also took the position of interim leader before securing the full leadership at convention.

Danny Williams resigned the leadership of the Progressive Conservative Party of Newfoundland and Labrador, similarly choosing to step down immediately rather than serving until a leadership convention, and Deputy Premier Kathy Dunderdale was elevated to the interim leadership of the party and to the premiership.

Interim parliamentary leaders

In certain circumstances, a party may also have an interim parliamentary leader who is ''not'' officially the party's leader, particularly when the party leader is not a sitting member of the legislature. Herb Gray served as parliamentary leader of the Liberals following the selection of Jean Chrétien as leader in 1990, until Chrétien could run in a by-election to enter the House of Commons. Similarly, Bob Runciman served as parliamentary leader of the Ontario Progressive Conservative Party following the 2007 election, in which party leader John Tory lost his seat in the legislature. He became the party's full interim leader in 2009 after Tory was defeated in an attempt to re-enter the Legislative Assembly in a by-election.

Bill Graham served as interim parliamentary leader of the Liberals in early 2006, while outgoing party leader Paul Martin was still sitting as an MP and retained the formal leadership of the party. After this situation created some media confusion over which man would lead the party into an election if one were to occur, Martin stepped down as party leader in March, and Graham assumed the full interim leadership until Stéphane Dion was selected as leader in December.

Louis Plamondon became interim parliamentary leader of the Bloc Québécois on June 2, 2011, at the beginning of the first session of the 41st Canadian Parliament, following the 2011 federal election and the defeat and resignation of BQ leader Gilles Duceppe, while Vivian Barbot succeeded Duceppe as interim president of the BQ.

Major James Coldwell became parliamentary leader of the Co-operative Commonwealth Federation in October 1940, following the stroke and incapacitation of party leader J. S. Woodsworth, who retained the title of "honorary president" (leader). Coldwell was officially elected leader in July 1942, several months following Woodsworth's death. After Coldwell lost his seat in the 1958 federal election, Hazen Argue became the party's parliamentary leader, before being elected as party leader in 1960. The CCF's successors, the New Democratic Party would twice name David Lewis as interim parliamentary leader on two occasions after the party's inaugural leader, Tommy Douglas failed to win a seat in parliament in 1962 and 1968 respectively. After Lewis lost his own seat at the 1974 election, Ed Broadbent became parliamentary leader of the party until his election as permanent leader the following year.
