I don't think Ottawa is for digitization. As a member in this forum once said Ottawa now is the new Mississauga. Which is simply the fast track route instead of some visa offices. The legend has it that straight forward cases were sent to Mississauga in addition to Indian applications to reduce the pressure on Indian Visa offices given that Indian apps are the majority. If you look now at cases moved to Ottawa it still follows the same pattern. Cases from USA, UK, New Zealand, Australia, Hong Kong, etc. and India.
