Canada
The joint US/Canadian ADIZ, which is almost exclusively over water, serves as a national defense boundary for aerial incursions. Any aircraft that wishes to fly in or through the boundary must file either a Defense Visual Flight Rules (DVFR) flight plan or an Instrument Flight Rules (IFR) flight plan before crossing the ADIZ. The aircraft must have an operational radar transponder and maintain two-way radio contact while approaching and crossing the North American ADIZ.
