The NAAD System uses the Statistics Canada – Standard Geographical Classification 2006 (Updated May 2010) from Statistic Canada (LINK). This standard allows multilevel fields for alert location and an alert can have a single or any combination from these location levels:
Province/Territory > Census Division > Census Subdivision.
According to this standard an alert issued for Quebec will have an SGC code “24” and if issued for a location within Quebec it will always start with an SGC code of “24…”. It depends how an LMD is receiving the alerts, if they have a tool available then it can be used to filter the alerts for location code “24” or codes starting as “24… ”.
Within the alert CAP file this code can be found in the following fields (an alert can have multiple geocode fields for multiple locations):
