The Vancouver Island Health Authority filed a complaint after a person claiming to be a nurse posted the ad on the website UsedVictoria earlier this week, offering a vial of H1N1 vaccine to the highest bidder.
Website administrators refused to co-operate with the investigation, but police say a 32-year-old man turned himself in and apologized for tying up police resources.
No charges were laid but police cautioned the public that such online websites have "limited quality control" and don't check the validity of the ads posted on their sites.
Health Canada and the Competition Bureau have issued a warning about scams linked to the H1N1 virus, and urged Canadians not to buy products claiming to fight or prevent swine flu.
The ad has been removed but the UsedVictoria site is still offering an "immune boost inhaler kit" to help prevent the virus.
