The Ontario government is looking for “creative” new ways to get the attention of Craigslist after the American company ignored repeated requests to remove prostitution ads from its Canadian websites, Attorney General Chris Bentley said Thursday.

Bentley first wrote to Craigslist CEO Jim Buckmaster in September, just after the San Francisco-based company bowed to pressure from several U.S. attorney generals and removed the prostitution ads from its sites south of the border.

Since then, Manitoba, Saskatchewan, Alberta and the federal government have also written the online classified ad service to ask that the prostitution ads be removed in Canada.

So far, Craigslist has done nothing other than to request a meeting with Ontario officials, allowing hundreds of ads for hookers to be posted on its Canadian sites every day.
