The alignment of the Canadian Air Defence Identification Zone (CADIZ) with Canada’s sovereign airspace and its approaches became effective today at 9:01 Coordinated Universal Time (UTC) through the publication of revised coordinates in aviation publications.

“Canada remains committed to supporting the North American Aerospace Defense Command. The alignment of the Canadian Air Defence Identification Zone with our sovereign airspace and its approaches is another expression of our responsibility for the Arctic. It is also a significant milestone in implementing yet another initiative from our Defence Policy, Strong, Secure, Engaged.”

The Honourable Harjit S. Sajjan, Minister of National Defence

• Air Defence Identification Zones (ADIZ) are tools used by states to monitor and identify aircraft approaching their sovereign airspace and assess possible threats to national security. It is a common practice in the international community.

• The Canadian Air Defence Identification Zone (CADIZ) is now aligned with Canada’s sovereign airspace and its approaches. The CADIZ alignment covers the entire Canadian Arctic archipelago.

• The Canadian Armed Forces, along with Transport Canada and Nav Canada, have worked together to implement the change smoothly with minimal impact to the aviation community, through notices in appropriate aviation publications affecting transit into Canada’s sovereign airspace.
