Fred Bass is a former city councillor, environmentalist and a preventive medicine physician in Vancouver, British Columbia, Canada.

He earned a master's degree in epidemiology at the Harvard School of Public Health and a Doctor of Science at Johns Hopkins, writing a thesis on medical care use attributable to cigarette smoking.

"[3] Known for having a quirky side, his initiatives included hiring a plane to fly an anti-tobacco banner at a fireworks event that was sponsored by Benson & Hedges,[5] and organizing a race with live turkeys in Robson Square to publicize a cold-turkey campaign.

Bass, concerned about global warming, entered electoral politics in 1996 as a candidate for Vancouver's civic Green Party under the leadership of Stuart Parker but was defeated by a wide margin.

Bass was outspoken in his opposition to the expansion of gambling and to excessive expenditures for rapid transit by a faction of his party under the leadership of Mayor Larry Campbell.

Bass and councillors Tim Louis, David Cadman, Anne Roberts and Ellen Woodsworth remained in COPE.

In late 2006 he announced his aspiration to run for mayor in the next Vancouver civic election because of his concerns for respect, global warming, homelessness and lack of affordable housing.

[3] In May 2012, Bass was one of several protesters arrested in White Rock, BC for blocking a train that was carrying American coal destined for shipment to Asia.

[11][4] In 2019, Bass began to facilitate public workshops on "eco-resilience", which he describes as the capacity for individuals, households, communities, and ecosystems to respond to the stresses of environmental collapse.
