Canadian events

Canadian interpretations
Canadian rules
▪ Languages
▪ Issuer rights

The Most Critical Alerts…
• are the main interest of the political leaders
• are defined as “Broadcast Intrusive” within the Public Alerting
• Distributors are to apply intrusive measures in getting the message
out (pushing with bells and whistles)
• The Intrusive setting will be handled with the use of a <parameter>
tag in the NPAS layer of the CAP files
• NPAS to aggregate, validate, modify where necessary, and act as a
dispatch centre for the distributors within the NPAS community

Met. Service of Canada (MSC)…
• has built an implementation of CAP-CP as a guide to all other
Canadian efforts in public alerting
• Over 32000 MSC CAP-CP messages produced since June 2008
• So far…6 different “Feeds” (message conduits) created to
demonstrate message targeting…
Targeting by Location (city, location)
Targeting by Urgency (immediate, future, etc..)
Targeting by Event Kind (tornado, blizzard)
• This MSC implementation is known as the CAP Canadian Profile
“Reference Implementation”
• We see it as a template for Canadian public alerting stakeholders to follow for
interpretation and guidance of CAP and CAP-CP.
