Canadian music publishers are pushing for a levy to be made against ISPs there for downloading music over the Internet.

In a case currently before the Canadian Supreme Court, the Society of Composers, Authors and Music Publishers of Canada (SOCAN) is demanding an extension to the country's copyright laws to include foreign Web sites that offer music for download to Canadians: "I believe that those who benefit from selling access to music should compensate the creators," David Basskin, president of the Canadian Musical Reproduction Rights Agency told Associated Press.

Canada already operates a tariff on the sale of recordable CDs and blank cassettes to compensate artists. These have pulled in $20.5 million so far.

The Canadian Association of Internet Providers and several digital rights groups are opposing SOCAN's demands.

A ruling is expected within 6-12 months.
