VICTORIA -- The Green party will not run a candidate against NDP Leader Jagmeet Singh in the riding of Burnaby South.
Green Leader Elizabeth May says the decision is an extension of a "leader's courtesy," a long-standing Canadian parliamentary tradition that facilitates a newly elected party leader's entry to the House of Commons in an unopposed byelection.
She says in a statement the Greens believe it is right to step aside to allow the leader of "an important part of the political spectrum" to serve in Parliament.
Singh announced his candidacy for the federal riding after New Democrat MP Kennedy Stewart indicated he was stepping aside to run for mayor of Vancouver.
The Liberal and Conservative parties have not announced candidates in the riding, but the Liberals have said they will contest the byelection.
May received the leader's courtesy in 2008 when then-Liberal leader Stephane Dion chose not to run a candidate against her in Central Nova. She extended the same gesture to Dion.
In 2002, the Liberals and Conservatives stepped aside for Stephen Harper when he ran in a byelection held shortly after he became leader of the Canadian Alliance.
No date has been set for a byelection.
Singh sat in Ontario's legislature and served as the provincial NDP's deputy leader before he replaced Tom Mulcair as the federal leader.
