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.

Famous quotes containing the word canada:
“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.”
—Henry David Thoreau (1817–1862)
“What makes the United States government, on the whole, more tolerable—I mean for us lucky white men—is the fact that there is so much less of government with us.... But in Canada you are reminded of the government every day. It parades itself before you. It is not content to be the servant, but will be the master; and every day it goes out to the Plains of Abraham or to the Champs de Mars and exhibits itself and toots.”
—Henry David Thoreau (1817–1862)
“I see Canada as a country torn between a very northern, rather extraordinary, mystical spirit which it fears and its desire to present itself to the world as a Scotch banker.”
—Robertson Davies (b. 1913)
