Reward offered for identifying who paid for pro-Bremner ads

A reward has been offered for information about the people behind the veiled entity that is running an ad campaign in support of Vancouver mayoral candidate Hector Bremner.
The mystery group rented space on roadside billboards for ads that feature Bremner’s photo and a re-worded version of his campaign slogan. The mystery group claimed in its ads to be Vancouverites for Affordable Housing, but that existing group of grassroots housing advocates says it has nothing to do
