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.

—Irving Layton (b. 1912)
“Though the words Canada East on the map stretch over many rivers and lakes and unexplored wildernesses, the actual Canada, which might be the colored portion of the map, is but a little clearing on the banks of the river, which one of those syllables would more than cover.”

“I fear that I have not got much to say about Canada, not having seen much; what I got by going to Canada was a cold.”
