The Green Party of Vancouver will run Pete Fry in the October 14 civic by-election.
Fry will seek to fill the city council seat left vacant after Vision Vancouver's Geoff Meggs stepped down to become the chief of staff for B.C. premier John Horgan.
Fry, who is the son of longtime federal MP Hedy Fry, said he wants to focus on creating affordable housing and "throttling" luxury developments, while supporting Green Party leader Adriane Carr in council meetings.
"It's just the way the city is being run. I think it's time for a change and I think people are quite sick of Vision Vancouver and the way things have been going and I hope to bring that change," said Fry, who previously ran for council in 2014.
"This is an opportunity to actually really show what we can do by having two greens on council, because you need that second vote to pass motions."
The two largest parties in Vancouver, Vision Vancouver and the NPA, have yet to select their candidates.
