Vancouver Mayor Gregor Robertson not seeking re-election this fall

Vancouver Mayor Gregor Robertson says he's not seeking re-election this fall after three terms in office.

Robertson says he reflected on his future in politics over the holidays and decided it's time to step aside to make space for new leaders.

He was first elected mayor in 2008 and by the time he completes his term this October, he'll have served the longest consecutive run as a mayor in the city's history.

In a Facebook post, Robertson touted his efforts to combat homelessness, build partnerships with Indigenous people and fight climate change, adding he'll continue to support his party in the upcoming election campaign.

His Vision Vancouver party recently lost a council seat during a fall byelection, with voters supporting the opposition Non-Partisan Association's Hector Bremner.

Robertson is known for leading the city as it hosted the 2010 Olympics, implementing a "greenest city" agenda, and for bringing in an empty homes tax to combat soaring housing costs.
