The MAPL system is designed primarily to increase exposure of Canadian musical performers, lyricists and composers to Canadian audiences. It also strives to strengthen the Canadian music industry, including the creative and production components.

To qualify as Canadian content, a musical selection must generally fulfil at least two of the following conditions:

• M (music): the music is composed entirely by a Canadian
• A (artist): the music is, or the lyrics are, performed principally by a Canadian
• P (performance): the musical selection consists of a live performance that is
  • recorded wholly in Canada, or
  • performed wholly in Canada and broadcast live in Canada
• L (lyrics): the lyrics are written entirely by a Canadian

I think it could be added to MBS-8393 as an attribute.
