Toronto's crack-smoking Mayor Rob Ford is never done campaigning -- not only did he throw down big money to party with hot chicks in Hollywood after the Oscars last night ... he actually handed out Ford-themed commemorative magnets to his female admirers.

Actress/socialite Meredith Thomas tells TMZ, she and a friend ran into Ford at the post-Oscars bash at the W Hollywood -- where they found him chilling in his own private cabana by the pool.

Thomas says she asked Ford for a photo and he obliged -- then handed her and her friend a Rob Ford Mayor magnet and a business card. Thomas says Rob asked her to stick around, but she declined.

As for Ford's poolside cabana -- it didn't come cheap. We're told the average price for cabanas Sunday night was $2,500 a pop, including booze.

Magnets attract ... but they also repel.
