Warner Bros. has banned all promotional film screenings in Canada in response to what it says is lax anti-piracy legislation. The policy goes into effect with the studio’s upcoming release of Ocean’s Thirteen on June 8, at the start of the busy summer season, which will also see Warner release the highly anticipated Harry Potter and the Order of the Phoenix.

In a Monday release, the company claimed that nearly 70% of its titles have been camcorded in Canada in the last 18 months, making it ‘the main source for most of the world’s film piracy.’

‘We regret having to cancel our screenings in Canada but our studio must take steps to protect not only our branded assets but our commitment to our filmmakers and to theatres all around the world,’ said Dan Fellman, president of Warner Bros. Pictures domestic.

The ban does not include advance press screenings.
