Vancouver’s upcoming city council byelection has its first candidate.

Environmental lawyer and transportation activist Lucy Maloney announced Tuesday she was throwing her hat in the ring for OneCity Vancouver.

The city is holding a byelection on April 7 to fill two vacant council seats.

OneCity Coun. Christine Boyle resigned her seat after being elected to the B.C. legislature in the 2024 provincial election, and Vancouver Green Coun. Adriane Carr announced her own resignation earlier this month.

In unveiling her candidacy Tuesday, she took aim at the city’s mayor.

“Ken Sim barely shows up for work, in fact, he’s missed a third of votes at council,” she said.

“When he does bother to show up it’s to make decisions that damage our city, like tearing down temporary modular housing, like abolishing Vancouver’s renter office, and failing to redesign dangerous intersections to make them safe.”

Maloney counts one of Sim’s former allies, independent Park Commissioner and former ABC Vancouver member Scott Jensen, among her supporters. Jensen and two other ABC commissioners broke with Sim over his plans to eliminate the Vancouver Park Board.

OneCity is the first civic party to unveil a candidate for the byelection. The Vancouver Greens, OneCity and COPE have said they will each run just one candidate each to reduce the chance of splitting the progressive vote.

Former councillor and mayoral candidate Colleen Hardwick’s TEAM for a Livable Vancouver says it will run two candidates.

ABC Vancouver, which holds a majority on council which will not be affected by the results of the byelection, is expected to run two candidates.
