The Government of Canada has announced that the CP140 Aurora will be replaced by the P-8A Poseidon.  It is expected that a new fleet of 16 aircraft will be fully operational by 2032.   The following opinion piece written by Ernie Cable posits that Canada made the right choice when choosing the Boeing P-8A, developed from the BOEING 737-NG (New Generation) airliner.
