The posters feature a picture of the van and claim that a man named Garry, his wife Jennifer and another man named Trevor are out to give back to the community.
In addition, the posters suggest the trio offer "a number of other services to women," though what those services might be aren't specified.
Const. Jason Michalyshen with the Winnipeg police say if anyone in the public has information to share on the supposed service, they should call police.
He says officers have reached out to the Winnipeg Regional Health Authority, which runs its own mobile public health service, but the two are in no way connected.
