Nav Canada has decided to install flight control centres and to close control towers in some regions.

4. Operators referred to in paragraph 3 shall make appropriate arrangements to ensure that data exchanges can be established between their aircraft having data link capability and all ATS units which may control the flights they operate in the airspace referred to in Article 1(3), with due regard to possible coverage limitations inherent in the communication technology used.

The approach has involved a comprehensive re-assessment of the ways in which we use airspace. That means looking at the way that the airspace is divided up, at the ways in which aircraft are allocated routes, at the ways in which flights are monitored once they have begun and also at existing and potential procedures and legislation.
